EP-410 Rachel Li, Charles Denby, and Nick Harris of Berkeley Yeast

If you're a beer fan, it's likely you know about the core ingredients in every recipe: hops, malt, water, yeast. Even if you're not an enthusiast, you may have at least heard about a hop varietal every now and then. But it's that last item—the yeast—that is getting renewed and extraordinary scientific interest as companies forge into a new frontier of fermentation. In this episode, we're joined by the three founding members of Berkeley Yeast, all scientists who came together with the goal of pushing the microorganisms to new levels in order to create new flavors in beer. Whether it's recreating the taste of hops or adding nuances of fruit—the kind of yeast this company is making has the ability to not just alter our beer, but our perception of what's possible in the brewing process. One brewer from San Francisco's Cellarmaker Brewing once said that Berkeley Yeast is "messing around at a level that's just so far beyond what anyone else is doing," while another from Monterey's Alvarado Street Brewery said once that "It's mind-boggling how these flavors could be created with no fruit." Joining me to talk about it all are Rachel Li, Charles Denby, and Nick Harris, who launched their startup from origins at UC Berkeley and in recent years have rapidly become a trusted source for brewers around the country looking to push the boundaries of what their fermentations can do. We'll hear about how and why they started the company, the kinds of yeast they're creating, and most importantly, why now is the moment this is all happening and changing the minds of brewers. Because your taste buds are next.
