Imagine an unseen universe, one that exists literally beneath our notice. One that is only visible to human eyes when magnified by powerful instruments. Then, we see a veritable garden of diversity-communities of microbes living in cooperation and competition, much as we humans do in our macro-sized world.

"The book weaves in reflections on art, religion, culture, music, and more, so even if you’re not an epicure, there’s something for everyone."—Men's Journal

Bestselling author Sandor Katz—an “unlikely rock star of the American food scene” (New York Times), with over 500,000 books sold—gets personal about the deeper meanings of fermentation.

In 2012, Sandor Ellix Katz published The Art of Fermentation, which quickly became the bible for foodies around the world, a runaway bestseller, and a James Beard Book Award winner. Since then his work has gone on to inspire countless professionals and home cooks worldwide, bringing fermentation into the mainstream.

In Fermentation as Metaphor, stemming from his personal obsession with all things fermented, Katz meditates on his art and work, drawing connections between microbial communities and aspects of human culture: politics, religion, social and cultural movements, art, music, sexuality, identity, and even our individual thoughts and feelings. He informs his arguments with his vast knowledge of the fermentation process, which he describes as a slow, gentle, steady, yet unstoppable force for change.

Throughout this truly one-of-a-kind book, Katz showcases fifty mesmerizing, original images of otherworldly beings from an unseen universe—images of fermented foods and beverages that he has photographed using both a stereoscope and electron microscope—exalting microbial life from the level of “germs” to that of high art. When you see the raw beauty and complexity of microbial structures, Katz says, they will take you “far from absolute boundaries and rigid categories. They force us to reconceptualize. They make us ferment.”

Fermentation as Metaphor broadens and redefines our relationship with food and fermentation. It’s the perfect gift for serious foodies, fans of fermentation, and non-fiction readers alike.
