Bootleg Biology is an open source yeast (and wild bugs) project whose goal is to create the world’s most diverse library of microbes for the creation of fermented foods and beverages.

All microbes are sourced and isolated from “bootleg” sources such as: backyards, orchards, kombucha, yogurt, honey, fruit, bottle dregs, and whatever else we can get our hands on.

The Bootleg Biology community includes experimental breweries and enthusiasts who contribute their yeast or house cultures to the project, with the shared goal of enriching everyone’s access to diverse microbes.  

Bootleg Biology is the first organization to pioneer the collection and cultivation of official yeast strains for U.S. cities and states as part of its Local Yeast Project, beginning with the original S. arlingtonesis.
