About this episode
Since ancient times humans have harnessed the power of microbes to preserve food and enhance its flavours. Rich and complex food cultures have developed that use this power in a process called fermentation - making pickles, breads, wines and much, much more. Sheila Dillon joins Sandor Katz - author and 'fermentation revivalist' - to find out more about the wonders of fermentation as well as our very relationship with these microbes. Producer: Rich Ward.
