Hannah Ruhamah Crum is the Founder of KombuchaKamp.com, Co-Founder of Kombucha Brewers International, and the acclaimed author of The Big Book of Kombucha, often hailed as “the Bible of Kombucha.” A lifelong fermentation educator and self-described Mother to Bazillions of Microbes, Hannah has been a guiding force in the modern kombucha movement for more than two decades.
Her website, KombuchaKamp.com, is the world’s leading source for DNA-sequenced, heirloom starter cultures, in-depth courses, and an encyclopedic library of fermentation wisdom trusted by hundreds of thousands of brewers worldwide… all in service of making the world healthier, one gut at a time.
Through her work with Kombucha Brewers International, the trade organization dedicated to advancing public awareness of kombucha, establishing rigorous commercial standards, and advocating for fair, science-based legislation through support of the KOMBUCHA Act, Hannah has been an indispensable ally to both commercial and home brewers alike. She continues to stand at the forefront of the movement as a global goodwill ambassador for the hundreds of thousands who brew, the millions who enjoy kombucha, and the gajillions of microbes she has helped bring into balance with human health.
Her upcoming book, Daily Ferments, invites readers to cultivate daily rituals and routines rooted in microbial mindfulness - bridging fermentation, nourishment, and holistic well-being in everyday life.
