Sandor Ellix Katz

Fermentation guru Sandor Katz returns to Fresh Air for a lively discussion about cured meats, cheeses — and some fermented beverages (notably wine and beer).

Self-described "fermentation revivalist" Sandor Katz says "the creative space" between fresh and rotten is the root of most of humanity's prized delicacies. His new book, The Art of Fermentation, explores the ancient culinary art form.
