This episode developed thanks to Nick, who thought it would be a good time to revisit a bit of my history in coffee to reconnect with long-time listeners, and to share a bit more about myself with new listeners. We started this podcast about 6 years ago, and if you've been through all 72 episodes, you probably have a good idea about my coffee philosophies. But I also know that not everyone enjoys, or maybe even has the time to go back and start at the very beginning of a podcast. So we thought it would be a good opportunity to give you a bit of my coffee origin story, and a manifesto of sorts, all under one roof.

Some of the questions in this episode: What typically happens to the water, along with cascara and whatever else is part of a fermentation, after the fermentation has been completed? Cascara is sometimes processed into a secondary product, cascara tea. Are there other secondary products that are made? As a roaster, what should we put on our bags to better point towards the farm? What's the consensus on adding flavor descriptors to bags? Do or don't? How can I store coffee cherry for 2–3 days without creating high damage?

On today's episode I will be updating you on the coffee we made this harvest season and speaking of the importance of blends. If you’ve listened to even 1 other episode of this podcast, you’ll know that I'm usually trying to discourage the coffee industry from blindly adopting wine culture. Usually I share my thoughts that adopting a wine model benefits consumers more than producers and further accentuates inequality between the coffee buyers and coffee producers. Usually I believe the wine mode does more harm than good. But here is a rare occasion where I think coffee could truly benefit from the wine model. In this episode I talk about: Identity shift from a wine person to a coffee person Why coffee could benefit from adopting the wine vintage model How I approach blending coffee lots in the season Is Coffee Hunter an outdated term? My risky coffee sales strategy Inquiries about coffee samples or future Fermentation Training Camps: info.luxiacoffee@gmail.com Support the show on Patreon to join our live Discord hangouts, and get access to research papers, transcripts and videos.

This episode also comes on the heels of our recent trip to London. Our very first stop was the Nagare coffee shop in Shoreditch in North London. Nick and I do what we usually do when we step into a coffee shop and order the pour overs. They had 2 different coffees on the menu for a pour over so we got one of each and sat back at our cute little table in a cozy cafe, and it was only when we looked down at our empty Kinto ceramic cups that we finally realized we had paid 18£ ($23 dollars!) for 2 small cups of black coffee. I experienced sticker shock because we have been living on farms in Colombia and Guatemala for the last 4 years and we are very out of touch with big city prices. I knew London was going to be expensive but I was not emotionally prepared to spend $11/cup on our daily coffee. Nick and I needed more coffee that morning but if we got 2 more cups at Nagare, we would be close to $50 and we hadn’t even had breakfast yet. In my head, a voice was saying, dang $11 is an expensive cup of coffee. And then immediately another voice said, hold on.... "don’t we want the price of a cup of coffee to rise?" Aren't low coffee prices a big part of the problem with our supply chain? The conversation about the price of a cup of coffee is one I have often. What should coffee cost? Who gets to set the price? How does price reflect value? The conversation about price and value is often at the forefront of my mind because there is such a disparity between what a coffee producer gets paid for growing and processing the coffee and what a consumer pays for a cup of coffee made from their raw material.

Today I bring you a conversation with an extraordinary producer: Rani from Java Halu in Indonesia. I do not use this word lightly. Rani is a truly exceptional person and my new coffee crush. I met her because she was the only woman who attended FTC Indonesia in June. Each previous FTC has been minimum 50% female, this is very important to me because so many coffee spaces are still very male dominated. During our plan for FTC Indonesia, I handed over many of the logistics to the Bandung Coffee Exchange team. It was only after 23 tickets were sold that I looked at the roaster and saw 22 males and 1 female. I thought this might make Rani a bit shy but I couldn’t have been more wrong. In this episode we talk about: How her past influences her present how she developed her business acumen turning waste into new money civet coffee without civets the contradiction of “specialty wet-hulled” coffee why women are important to the sucess of her business the importance of getting research out of the lab and into the farms RESOURCES Inquiries about coffee samples or future Fermentation Training Camps: info.luxiacoffee@gmail.com Support the show on Patreon to join our live Discord hangouts, and get access to research papers, transcripts and videos.

The conversation with Tom Owen is wide ranging, but one main theme we talk about is coffee travel and tourism. How the host and guest dynamics play out including the unintentional burden we may be placing on coffee producers when we visit them.

In 2009, Vava Angwenyi started VAVA COFFEE – a Benefit Corporation (B-corp) with a Social enterprise model that exports, roasts and consults on coffee value chains, the organization aims to contribute to better future prospects for coffee communities and the industry as a whole. The company ensures sustainable livelihoods for the people and communities in which it works. Vava is also the co-founder and director of business development & fundraising at GENTE DEL FUTURO (People of the Future). GDF formed in 2017 is an organization born out of a partnership between African Plantations Kilimanjaro, Vava Coffee and Oro Molido three private sector players within the coffee sector to tackle two of the main problems we face as an industry - Producer profitability and Next generation involvement. Gente Del Futuro’s focus is to amplify the voices of youth by creating economic empowerment, choices and sustainability for the coffee industry. The organization offers young people a unique and one of a kind learning opportunity by fusing coffee cultures and knowledge from three different growing origins : Tanzania, Kenya and Colombia. Vava holds a Masters degree-Msc in International Finance and Management from University of Groningen as well as Certificate in Global Asset Management from Warrington College of Business, UF and a BSC in Statistics & Actuarial Science from University of Western Ontario- Canada. Vava’s vision is to challenge the status quo and promote positive social disruption within the Coffee industry. This vision comes from an inborn passion for transformative change and a drive to promote the sustainable production of coffee at various origins by tracing the production of high quality coffee beans to the independent smallholder coffee farmer, who works day in and day out, against major obstacles and with meager resources to produce some of the world’s best tasting coffees, often without an understanding or appreciation of the final fruits of their labor. Vava is also a Q grader and was part of the 2015 IVLP program a prestigious State Department sponsored program. Vava Coffee has also been recognized over the years for its grassroots initiatives and contribution to smallholder farming communities and Youth in agriculture.

Next time you set about making your morning coffee, take a moment to peruse the info on your bag of beans. What do you notice? The variety of beans? Flavor notes? Technical details on where the coffee was grown? They're not so different from the sort of blurb you might find on the back of a wine bottle in many ways. And that’s intentional. Specialty coffee has taken a lot from the world of wine. But could the increasing overlaps be a problem for coffee farmers — or even dangerous? In this episode, Scott and Jools join forces with coffee processing specialist and former winemaker Lucia Solis from the Making Coffee podcast to dive deeper into where our coffee comes from and what (if anything) wine's got to do with it. Lucia talks to coffee producer Karla Boza from the Finca San Antonio Amatepec coffee farm in El Salvador and vintner Todd Kohn from the Wayfarer Vineyard in California to shed some light on the techniques behind picking, transporting and processing their precious produce. Take a sip on this (soon-to-be-a-good) vintage episode to pique your curiosity about how coffee and wine are made, and why it matters. — Follow Karla Boza’s farm and Todd’s winery on Instagram Tag our Instagram handles: James Harper / Filter Stories Jools Walker / Lady Velo Scott Bentley / Caffeine Magazine James' Podcasts History of Coffee (do not miss this series!)

As many of you know, we've started doing live hang out after the episodes on Discord a week after the podcast comes out. I find this valuable because I get to hear from listeners and we create our own podcast after the podcast together. In the most recent gathering I had Felipe, Jose and Lucas from Ep 38 on the discussion so listeners of the podcast could ask them questions directly. A few things stuck out to me from that conversation that I want to share here because what started as a fun hang out turned out to provide a key insight for coffee producers. In this episode we talk about: Tank Additions: Mango, lemons, cinnamon Wine additions: sugar and acid Transparency: what does it mean and who benefits Enzymes vs Microbes like yeast and bacteria How fermentation is like gravity Support the show on Patreon to join our live Discord hangouts.

Do you drink kombucha? Coming from California, kombucha is about as normal as orange juice. But I imagine it might not be as popular in other parts of the world. Kombucha is probably more popular in North America and Europe (coffee importing countries) and probably very rare in coffee producing countries. I can imagine a near future where buyers are drawn to or supportive of kombucha process without understanding what they may be asking producers to do. Or similarly, producers wanting to be ahead of the curve and differentiate their coffee in a new way borrowing methods from beer and wine. My hope is that this episode helps coffee producers experiment intelligently and with intention, to maximize positive results. If you’re a coffee buyer or consumer, I hope you’ll be curious and critical if you see these words pop up on a label.

Today's episode is another in a series hearing from coffee producers from all parts of the world. I think one of the common traps we can get into is thinking and talking about "The" coffee farmer. Or "The Average Coffee Farmer." As if coffee farmers are a monolith. The average doesn’t exist. The people who grow and produce coffee are a very diverse group who do it for different reasons in very different conditions. It’s our nature, that when we learn something new, to compare it to what we already know, we learn by grouping and recognizing patterns and assigning categories. We take large amounts of information and shrink it, and distill it until it’s a small enough unit that we can attach a label. My hope with these episodes is to take a microscope to the group, get to know the individuals, how they think and what they think about.

Today’s questions all come from Dr. Mack in Bangkok, Thailand. Even though he is asking the question on behalf of coffee producers in Thailand, I wanted to answer them on the podcast because they are relevant to all of the newer coffee producing regions. Thailand didn’t export coffee until 1976! This is very recent and not a lot of time for coffee growers and producers to develop their craft and catch up with older coffee growing regions like Colombia, where I am living. Colombia was already exporting coffee in 1835. As new regions begin to grow coffee, the questions in this podcast will become more and more relevant. Dr. Mack's questions allow me to address a few things like: How to avoid fermentation during transportation from the farm to mill How to use yeast with rust resistant varieties How to do a honey or a natural process while avoiding mold growth (a common problem in humid tropical countries) Support the show on Patreon and get access to research papers.

Our sugar journey is almost complete as we round out the third installment in the Brix series. I hope the previous podcast episodes helped open your mind to some of the challenges we face in talking about sugar in the coffee industry. Today's episode focuses on ripeness and how counterintuitively sometimes measuring Brix can lead to lower quality coffee. And to help illustrate this point I'm sharing a lesson from one of my favorite industries: the cork industry. Specifically cork wine stoppers. In 2013 I was invited to visit Portugal as part of a Quality Control trip on behalf of the winery I worked for. In this episode we will talk about Brix and fruit maturity (ripeness), I will discuss the results of research done on a Brazilian coffee farm and we will see if there isn't a better instrument than a refractometer to help us look inside the coffee fruit and determine what will make a quality cup of coffee.

I hope the previous podcast episode helped open your mind to some of the challenges we face in talking about sugar in the coffee industry. In today's episode we are adding another element, another piece of the puzzle—the refractometer and the other instruments used to measure sugar. In today's episode we will see how a refractometer can give a high Brix reading even when there is zero sugar in the sample. Or, how it is possible to get negative Brix readings. I think understanding more about the the instruments we use, helps us understand the limitations of measuring Brix at all. Support the show on Patreon and get access to research papers.

Today you get to be a fly on the wall of a consulting session between myself and a coffee producer in Uganda. The Coffee Gardens is a newer project of coffee producers who have partnered with select coffee farmers in Eastern Uganda. They currently work directly with 300 small holder farmers. They have a micro-processing station in the foothills of Mount Elgon. This episode might be most relevant to a coffee producer, so if you know any, please pass this episode along to them. Especially if they are curious about using yeast to control their fermentations. Today we cover how to process undesirable cherries, we talk about the challenges in scaling up from a small trial to full scale lots. We also discuss yeast usage in very rural settings, is it even appropriate? At what volume should a producer consider using yeast? Even if you’re not a coffee producer I hope you will listen to the questions and concerns of a coffee producer and better understand their reality.

If you started the season with me in October you’ll remember that I started exploring the topic of what we lose when we take a plant from its native environment. Episode #25: A California Coffee Farm & Native vs. Local Yeasts looked at the relationship between coffee trees and the fermentation. Dr. Aimee Dudley’s research showed that the native microbes do not travel with the plant material and therefore all coffee fermentations outside of Ethiopia are non-native fermentations. Episode #26: Do Coffee Trees Talk? How Underground Fungi Affect Coffee Quality showed that when we take a plant from it’s native environment the microbes it needs to have strong immune response are also left behind. So we’ve touched on the above and below ground microbes that we leave behind. But is it only about microbes? Are microbes the most important thing we leave behind? I argue that it is not. As important as I think they are, I think there is something more valuable that is lost.

We usually hear about coffee from roasters or even people like me, who work with coffee producers but we are not producers ourselves. One of my podcast goals is to bring you directly to the source. Whether it's scientific research or hearing directly from coffee producers. Often we leave it to coffee professionals and educators to speak about coffee producers but it’s rare to hear directly from coffee producers about their motivations and challenges. And even when we do hear from them on their social media channels, there is a hidden pressure to present a rosy version of reality. Today’s conversation is with Mark from Finca Rosenheim in the Villa Rica region in Peru. This conversation is an honest look at some of the challenges producers rarely get to talk about. I asked Mark about organic certifications, climate challenges, coffee competitions, crop diversification, and what happens when markets can’t rebalance themselves.

What is left behind when coffee moves to new locations. What is the trade off for innovation? This episode looks at what else we potentially leave behind when we introduce new plant material to non-native locations. The inspiration for this episode was a beautiful book by Peter Wohlleben called The Hidden Life of Trees. In it, Peter talks about native forests vs planted forests and the differences we (humans) are able to perceive. One of the example trees in Peter's book are oak trees. This was an interesting cross over for me because oak is very important for winemaking. Most of red wine is aged in oak barrels and many Chardonnay's too. This episode is filled with wine information on barrels, tastings and stories of my time in the wine industry. I enjoyed putting this episode together and I hope you enjoy listening to it.

This week I want to talk to you about where native coffee yeast come from. If you are concerned about coffee flavor manipulation by yeast, I hope by the end of the episode you have a broader understanding of where "native" yeast originally came from. To help illustrate the point, we start with non traditional coffee growing regions like Southern California. In the episode I will also be sharing research from Dr. Amiee Dudley. I met Dr. Aimee Dudley in 2017 during SCA EXPO in Seattle when we were on a Re:CO Panel together talking about yeast. I was offering the perspective of practical application of yeast, how coffee producers in situ could use it and Dr. Dudley was presenting her research on yeast genetics.

What happens when the best in the world can't tell if a wine comes from the Willamette Valley in Oregon or Burgundy, France? What happens when the experts can't tell if the bubbles are from Champagne or California. Does a place really have a taste? Can we find it in the glass? That is the premise of terroir, tasting the land, localizing the product. But often, when put "terroir" to the test it cannot be found. Today's episode starts with the story of the 1976 Judgement of Paris tasting, a famous part of wine history that pitted French terroir-driven wines against terroir-less California wines. The competition had a blind tasting for red wine and for white wines. The red wines were predominantly Cabernet Sauvignon and the white wines were the Chardonnay variety. We are also going to see what happens when Terroir is used as a basis for certifications. I'll share with you some of the limitations of the "geographic protectionism" and the Appellation d'Origine Contrôlée (AOC) system. Certifications are usually protective tools but sometimes they can work against the producers they are meant to protect. How can such a romantic and noble concept, tasting the land, respecting nature - work against producers?

Welcome to the next installment of terroir in coffee. This one little word contains a whole world of history and has an important role in the economic viability of certain agricultural products. After the last episode I heard from some of you who wished I had talked about soil minerals and plant nutrition from soil. Others also asked about the wine making regions like Bordeaux where Terroir is regulated by french law. I cover both of these concerns in todays episode before we get to discuss what I really wanted the episode to be about: microbes and morality. There is an unspoken understanding that products that express terroir are more moral than others. I wanted to give you an episode that focused on microbiology, that talked about the yeast and bacteria that contribute to a "taste of place" but I couldn't do it without including the human perception that products that express terroir, products that are "transparent" are superior. I think we need to be really careful because science doesn't support this view. Any moral component of terroir is a choice to see it through a religious and political lens. I want to challenge your views on "transparency" and "intrinsic quality".

I'm so excited for you to join me in this discussion about terroir. Terroir comes from latin, for terra - soil. Also translated as land, or “taste of the land”. Terroir is predominantly a wine concept, so why are we even talking about it in reference to coffee? If you’ve listened to other episodes, you’ll know that there are certain concepts that the coffee industry likes to borrow from the wine industry. We’ve talked about some of the really bad ones, like using wine or beer tanks to ferment coffee or how a Q grader is not like a sommelier . From the outside we see the concept used in wine to justify the high prices of a French wine, perhaps we associate it with valuing the land, a sense of place. We know it’s connected to soil, so maybe we assume that terroir also has to do with soil health. This makes terroir seem like it would be a positive concept to adopt. I see how tempting it is to think that coffee could benefit from adopting this way of speaking about coffee farms and how it can help sell the coffee beverages at higher prices. Also, it sounds so romantic, and the specialty coffee industry loves romance. But similar to my argument about “anaerobic fermentation” , terroir faces a similar problem- the word is vaguely understood at best, and then repeated and made familiar by sheer repetition, not by true understanding. Many of us have a hard time defining this word if we are asked. I have made this episode to give you a background into the origins of the word so that before we dive head first into regular use in the coffee industry, we have a better understanding of what it means. While most student of winemaking take terroir for granted, as a given, I was lucky that one of my UC Davis professors challenged the idea. The historical origins are from the book Terroir and Other Myths of Winegrowing by Mark A Matthews. I highly recommend this book for those wanting to go deeper after today's episode.

Have you ever wondered what would happen if you introduced foreign yeast and bacteria into a coffee farm? Or maybe you're curious if we can speed up a long fermentation by warming it up. How does post harvest processing affect the density of the seed? In today's podcast episode I’m answering listener questions like these and also sharing how I approach designing a fermentation. When I was planning this podcast I knew that I wanted it to be a community supported project and that I did not want to rely on advertisements or sponsors that can be annoying or distracting to the information I want to share. The Patreon supporters are a group of individuals who care about coffee education and support me and this project.

For those who know, it may not come as a surprise when I share how much I love tea. But professionally, today is the day I come out of the tea closet. I drink logarithmic levels of tea compared to coffee, and the more I confess that, the more other coffee professionals share with me that they too love specialty teas. Unfortunately I think coffee and tea are often lumped together in similar categories but they have very different histories and I think it’s worth trying to de-couple these beverages. Today's episode serves as an introduction the basics of specialty tea and will be the first of many episodes exploring the processing and history of this beverage. Our guide through the world of tea is my friend Aurora Prehn. She is a researcher of people and plants. Her undergraduate work was a double major in Anthropology and environmental studies. She worked at Rishi Tea and Botanicals as a tea educator. In 2018 she then left to do a masters in ethnobotany in Canterbury, England, which she finished last fall.

In today's Making Coffee Podcast episode, we're taking a deep dive into anaerobic fermentation and how language reflects values. Specialty coffee is a young industry. In the consumer space we have only recently started to differentiate between processing styles like natural, washed and honey and now we’re jumping off the deep end into the microbiology of these processing styles. I wanted to record this episode because many Green Buyers ask me what Coffee Producers mean when they label their coffee like this and Coffee Producers ask me what the Green Buyers mean when they ask them for an anaerobic process. Both parties expect the other one has the answers. Even if the words are poorly understood they are still copied, pasted and repeated so much that they become familiar through sheer repetition. We see them so much that we can sometimes convince ourselves that we know what everyone is talking about, or we assume that at least they must know what they are talking about. But in my observations, it seems like at this point everyone has their individual, personal, un-scientific definition. And this is a problem because when everyone defines the words differently, we undermine the point of language to communicate. To Support this Podcast and become a Patron CLICK HERE Support the show

Today's Making Coffee Podcast episode is a continuation of the theme of coffee pickers and their role in quality. In the previous episode I shared my surprisingly difficult experience trying to source red ripe coffee cherry. It was surprisingly difficult to pay the farmers more for a different quality than they were used to picking because of the established system, a system that developed over decades as a response to chronically low coffee prices. It's important for me to share this with you because I don’t believe enough of us who enjoy drinking coffee realize how fragile our coffee supply is. Coffee is such a staple in our daily lives that I believe we simultaneously revere it for making our mornings more enjoyable and take it for granted. For example, many businesses offer free coffee, free coffee refills or free coffee with food. If you look around hotels, restaurants and gatherings you can often find more than 1 “FREE Coffee” sign. We expect that there will always be coffee. It seems so abundant that there is a real disconnect between the effort it takes to get that cup into our hands and what we are willing to pay for that work. Many of us would be turned off by a $5 cup of coffee but have also likely paid $15 to $20 for a glass of wine. Additionally, it's a lot less common to expect free wine.

Today's episode is part 1 of a 2 part series talking about the people who pick our coffee. In episode 15 we went deeply into how a molecule of sucrose in the coffee cherry pulp becomes a flavor compound like banana or peach and gets into the coffee seed. Flavor is an accessible entry point for specialness. However, I don’t like talking about flavor and coffee too much. I don’t think coffee flavor is what’s going to help the industry move closer towards long term stability. I think it’s most often a distraction of the larger picture. My concern is the coffee farmers, the people at the source of the value chain. I think focusing on flavor distracts us from the larger threats to coffee, like climate change, pests and diseases and—what I want to talk about specifically today—availability of labor.

Today's episode is very special because it was picked by the Making Coffee Podcast Patrons. I sent my patrons a poll on what they wanted to hear about next and the topic most people wanted to hear about was HOW fermentation impacts coffee flavor. How can the same yeast that makes bread rise also make my coffee taste like apricot or jasmine? Maybe you’ve thought that farmers added fruit to the coffee (and while this sometimes happens—it’s not the kind of flavor we are talking about today). Maybe you thought those flavor differences came from the different plant variety or that different countries of origin explains those differences. Those are important factors but that’s not the whole story. In this episode we will go deep into the biochemistry of how a yeast or bacteria can turn the glucose in the coffee fruit into various flavors ranging from lemongrass to mint to raspberries. There is also a question at the end about how baristas can communicate flavor in a simple way (without having to give a 30 minute science lecture) to their customers.

Join me in listening to this conversation with George Howell, where we cover topics such as Cup of Excellence, coffee pricing, processing styles, craftsmanship, additives in processing, kamikaze farmers, and much more. George was awarded the Lifetime Achievement award from the SCA in 1996, even before he helped found the Cup of Excellence program in 1999. He's accomplished a lot towards improving coffee quality and educating consumers on several fronts. What I admire most is that he continues to be an advocate for quality. He's been in the industry 46 years and I was surprised to learn that he continues to travel to maintain his relationships with coffee producers, and visits Antigua every year. Even though George has had a longer career in coffee than me, and we approach coffee from different points of view and with different backgrounds, I was surprised to learn how much we have in common regarding coffee processing.

Hello friends, Today I want to share an interview with Sofia Handtke from Mapache Coffee in El Salvador. I recorded this last November at the end of my time with them. That was my second season working with them and designing fermentation lots at their mill. Over the last 2 harvest seasons we've done about 40 different batches combining 4 strains of yeast, 3 cultivars and various lengths (# of hours in the tank) in an effort to create additional flavor options. I wanted to interview Sofia and Jan Carlo together but they have a small mill team and a lot of responsibilities so I caught them when I could. In the interview with Jan Carlo we spoke about how Mapache is embracing vertical integration, how he believes this current generation is more open to sharing information, and some of his struggles like disease pressures and how climate change has impacted his farming philosophy. You can catch my conversation with him HERE. In this conversation I ask Sofia to share her Q Grader experience and talk about her background in coffee. She believes that getting coffee producers and buyers using the same standard language is very important but unfortunately it’s still out of reach for many producers in Central and South America—this is a topic that deserves it’s own episode and it's in the works. She shares what it was like growing up in a coffee farm and how she and Jan Carlo are engaging their two teenage children to inspire them to see the coffee industry as a career option, unlike her parent’s generation, many of which had to abandon the industry because it was no longer a viable way to make a living.She shares some fantastic insights about coffee branding and marketing and the coffee gear she takes when she travels.

I'm at the halfway mark of this trip and I officially ran out of coffee. I mentioned before that a significant portion of my carry-on space was dedicated to roasted coffee. Bringing coffee from home would mean that towards the end I was drinking coffee that was about 2 months old. Generally, I don’t like to drink coffee that is over 2 months old. I don’t like stale coffee but what I’ve found is that many of us drink stale coffee. Maybe not on purpose but if you’re not actively paying attention to your coffee, I can assure you—you’re drinking stale coffee. And then we train ourselves to like it! As I mentioned in a previous episode, we prefer what is familiar. If we constantly drink stale coffee, we tend to prefer that profile. We think stale is normal. Freshness is elusive. Join me as I talk about freshness, staleness and buying coffee from producing countries. Support the show

Hello friends, In today’s podcast episode I get to do something a little different. Instead of giving you my thoughts on a particular coffee topic, I’m answering questions from 4 different listeners. Ideally I would like to have an episode for each question because they are rich with topics but many listeners have submitted questions through my website. The pile is growing quite large and I think it would be more helpful if I could keep answers brief to address a higher number of questions. Today's questions focus on fermentation, yeast, bacteria and temperature : I remain skeptical about the role and importance of fermentation on coffee quality and flavor. Would the amount of water added into the fermentation tank affect the concentration of fermentation by products found in the final product? Is fermentation temperature is largely responsible for flavor differences between submerged (in-water) and dry (out-of-water) coffee fermentations? I have always been curious as to whether it is primarily yeast or bacteria causing the fermentation inside the fruit? How would a taster know the difference between yeast and bacteria fermented coffee? Support the show

When most people hear that I’m going to Central America for work, they often say some variation of “how cool! you’re going to have such great coffee” which is true, but only because I haul most of if myself from The United States back to Central America in my suitcase. Consuming countries pay a higher price for good coffee - so by design the best coffee leaves the countries where it was produced. The coffee that remains is the stuff that wasn’t good enough to export and sell, so by design the locals drink the lower quality coffee. In this episode I share a story about drinking coffee with small-holder farmer that illuminated another part of the coffee quality problem. Support the show

In this episode, I had the chance to speak with Jan-Carlo Handtke of Mapache Coffee. Jan-Carlo shares important perspectives of what it's like to be a 5th generation producer today. When most people are leaving coffee, Jan-Carlo and his wife Sofia are doubling down, buying new farms and making significant investments in education and equipment. In this conversation we talk about the role of social media, selling coffee on the local market, and he also shares some of his struggles. We talk about coffee farm irrigation, his Q-grader story, shade trees, and so much more. Support the show

I want to start by thanking everyone who has reached out to me and sent questions/comments or just let me know that you enjoy listening. I started this podcast as my offering to chip away at the knowledge gap between coffee producers and consumers In today’s podcast episode we’re going to hear from 2 sides of the value chain in very different parts of the world. Brendan from Semilla Roasters in Canada gives the roaster perspective and later in the episode we hear from Vivek, a 4th generation coffee producer in India. He asks for advice because he’s unsure where to start. Can he learn to be a good cupper without having a Q grader license? To me, the gap is an issue because it determines power dynamics. The simple issue is: Producers who don’t cup their coffee don't have the power to improve their coffee. It’s an obvious statement but one that is frequently overlooked because it’s been the standard. Producers often rely on external parties to tell them this vital information. The buyer who is able to cup the coffees is the one who can determine the value. This alone is bad enough but I’ve seen it lead to a new disturbing trend. Since the buyers are generally more knowledgeable about the coffee’s quality and since they cup more than producers do, they are uniquely in a position to tell producers how to improve or change their coffee. Regardless of the good intentions, the buyer is dictating terms, the buyers is still the expert, the buyer has more knowledge, the buyer has more power. And I couldn’t leave this topic without talking about the word “ empower ” I was guilty of using this word to describe my work. It used to be part of my mission statement to “empower producers with unconventional practices”. I had that written on my profile and website. But as I discuss in this episode, that word now makes me feel uncomfortable and I’ve removed it from my website and avoid using it. After listening to today's episode, I hope you’ll consider avoiding it also.

I’m writing this from a hotel in the small town of Ataco, El Salvador. I’ve been away from home for 21 days out what will eventually be 120. It’s currently coffee harvest time in Central America this is the time of the year when I am traveling the most seeing clients at their mills and designing fermentation lots. This is an interesting industry because of the amount of travel required by many parties along the chain (farmers, producers, exporter, importers, roasters and cafes). All of these entities are usually located in different countries with different languages, time zones, cultures and customs. These far apart business need to work together and the best way to have a smooth business is to have strong relationships. The best way I can think of to have strong relationships is to travel and sit with each other face to face and get to know the other's culture. Unfortunately flying is a huge contributor of carbon emissions. I’ve struggled with the paradox since I started traveling heavily in 2014. At home, I am committed to reducing my environmental impact, I don’t have a car, I buy bulk foods in my own reusable containers, I compost all my food waste, Ive reduced my meat consumptions and I’ve stopped purchasing new clothes. Yet the amount of flying I do every year eclipses all the other efforts. Previous years I spent November to March alternating one week in Central America and one week at home. Sometimes even seeing 3 clients in 1 month and only being home for a handful of days. In addition to the environmental strain, there was a personal strain as well. That pace was difficult because It kept me constantly on the move and in airports, I was never home long enough to feel refreshed. There was a moment I felt like I might need to quit working in coffee because the travel was too demanding. To reduce my travel, this year I’m trying something different. Instead of going back and forth between Central America and the United States, I will stay in Central America all 4 months. My flying is dramatically reduced but not eliminated. Having such a dramatic carbon footprint is not in alignment with how I live the rest of my life, so I’m still working on how to reconcile that. Join me for today’s episode for more on this paradox and a harvest update. Support the show

You heard my experience getting my Q grader license on last weeks episode. Today’s podcast is a continuation of the Q grader discussion but focusing on its role with coffee producers. I mentioned that it’s tempting to use the wine Sommelier certification as a shorthand to describe the Q grader license because the Sommelier’s has been around much longer and its a more familiar term than Q grader. I’ve been guilty of using this shorthand in the past but its both lazy and inaccurate. I feel it's important to untangle these two tests because if we keep repeating it, eventually we will start to believe it. However tempting it is, these two certifications are different in a fundamental way. The sommelier certification is predominantly used by the service industry (restaurants, etc) and the Q grader license is used as a means of quality control for exporters, importers and roasters. The sommelier certification is consumer facing, it is not a means to improve wine production quality. There is very little overlap between a winemaker's world and a sommelier's world. In contrast the Q grader license has a significant overlap in the production and consumer worlds. I value the Q grader license and I'm glad to have a standardized method of coffee evaluation but there is one often overlooked detail that has nagged at me. Coffee producers are rarely Q graders, they are not the tasting experts, the buyers are. This means that everyone else in the value chain is more of an expert in tasting coffee than the people responsible for producing coffee. Most of us haven’t considered what it means when the consumer is more sophisticated than the producer. What kind of power dynamic is created when a specialty coffee buyer is more sophisticated than the person who is deciding the flavor profile of the coffee? I'm also curious about the system of cupping scores perpetuated with the Q grader system. Join me in today's episode as I imagine a world without coffee scores. Support the show

What is a Q Grader? In the coffee industry the Q Grader license is often compared to the sommelier exam in wine—this is a shorthand that can be useful to provide some vague ballpark approximation, but over the next 2 podcast episodes we will see how different these tests are. When I started to get serious about working in the coffee industry I was looking for ways to deepen my knowledge and the Q Grader license seemed like a good place to start. If I wanted to use fermentation techniques to improve coffee quality I would need to learn what the industry considered to be high quality. Because how can we agree on what is coffee quality, without speaking the same sensory language? To move the conversation of quality forward, I needed to differentiate between preference (coffees people like) and quality (agreed upon criteria that are independent of preference). I have definitely scored high quality coffees that were not in my preferred flavor profile—conversely just liking a coffee is not enough to qualify it as a good coffee. It needs to meet quality standards of acidity, structure, body, sweetness and balance. I believe it is important to be able to put our personal preferences in context when evaluating a coffee. Join me on today's episode as I share my experience with the Q Grader license.

I find the term " over fermentation " to be especially annoying. From a biology point of view this term is nonsense. When coffee professionals use this term it's understood to mean a defect, usually vinegar, "boozy" or like rotting fruit. Everyone agrees that it's a negative trait for a coffee to have. I think it's important to be able to identify this trait but I think this label has held fermentation back and made many (producers and roasters alike) shy away from a process that when controlled can enhance coffee quality. In this week's episode I answer a listener question about double fermentation and Brettanomyces that gives me an opportunity to untangle the concept from the name we've given it. "Double fermentation" is another common colloquial phrase mistaken for a scientific label. It gives the impression that there are two fermentations, but this is not what's happening biologically. I also talk about the Russian River Brewing Company in Windsor California. I visited earlier this year in July and got to see how they use Brettanomyces and try their Brett Beer. The coffee industry is borrowing from the Beer industry as well as the wine industry and beer yeasts are becoming more popular in mills across Central America. This is an exciting time for coffee microbiology but there are a few cautions I want to give about this particular yeast.

If you made it through last week's deep dive about how we talk about and label specialty coffee - you've earned your coffee-nerd badge! This week I want to pull back the lens and talk more broadly about quality and value. Instead of examining the rigidity of microbiology, this week's episode explores the subjective side of preference and what makes something "good". I tell you a little about my coffee tasting history and share the story of the best (and worst) cup of coffee I've ever had. Support the show

The first step in expanding the role of processing in the coffee quality conversation is how we label these coffees. I have noticed a lot of redundancy and confusion in how we describe the coffees. I've heard various forms of; fermented coffees, yeasted coffees, anaerobic fermentation, lactic process, acetic process. The labels we use set up the foundation, and I argue that when the labels are inaccurate the whole foundation is compromised. This area of fermentation in specialty coffee is just beginning and I think it's important to be as precise as possible as we move forward. In this episode I talk about why these names are incomplete at best and inaccurate at worst. I also answer the first listener question: "Is it possible to "capture" yeasts from our environment in our own farms and apply these to the fermentation to create our own profiles?" Support the show
