Welcome to the Wild Fermentation Portal!

Fermentation makes foods more nutritious, as well as delicious.

Microscopic organisms – our ancestors and allies – transform food and extend its usefulness. Fermentation is found in many forms throughout human cultures. Medical and scientific studies confirm what folklore has always understood: Fermented foods help people stay healthy.

Many of your favorite foods and drinks are probably fermented. For instance: Bread, Cheese, Wine, Beer, Mead, Cider, Chocolate, Coffee, Tea, Pickles, Sauerkraut, Kimchi, Miso, Tempeh, Soy Sauce, Vinegar, Yogurt, Kefir, Kombucha, and so much more….

I call myself a fermentation revivalist. I am a self-taught experimentalist. My obsession with all things fermented led me to teaching and writing about how to ferment foods and beverages, as well as the phenomenon of fermentation more broadly.

I am the author of six books:

The Art of Fermentation, which received a James Beard award and has been widely translated, was selected by The New York Times as one of “The 25 Most Influential Cookbooks From the Last 100 Years.” My books, along with the hundreds of fermentation workshops I have taught around the world, have helped to catalyze a broad revival of the fermentation arts.

This site is maintained by Sandor Ellix Katz, aka Sandorkraut. I have been fermenting since 1993. In order to share the fermentation wisdom I had learned and demystify home fermentation, I wrote a book called Wild Fermentation, published in 2003 by Chelsea Green. Since the book's publication, I have taught hundreds of fermentation workshops across North America and beyond, taking on a role I describe as a "fermentation revivalist." Newsweek called Wild Fermentation "the fermenting bible." Inspired by people I met talking about fermentation, I wrote a book about diverse activist projects to reclaim food, called The Revolution Will Not Be Microwaved (Chelsea Green, 2006). In 2012, with a decade more experience behind me, the unique opportunity to hear countless stories about fermentation practices, and answering thousands of troubleshooting questions, I shared an in-depth exploration of the topic, The Art of Fermentation. All three books are available for sale on this website, but the larger purpose of this website is to connect interested people with the abundant resources for learning about different fermentation practices that exist on the World Wide Web.
