Barebottle Brewing Co. is a San Francisco-based craft brewery founded in 2016 by Cornell Business School classmates Lester Koga, Michael Seitz, and Ben Sterling, who transitioned from award-winning homebrewers to professional brewers. The brewery is renowned for its innovative, crowd-sourced approach, regularly collaborating with local homebrewing communities to develop new beers through competitions where winning recipes are brewed and served in their taprooms. With locations in Bernal Heights, Salesforce Park, Santa Clara, and Menlo Park, Barebottle offers a diverse range of beers, wines, and even house-roasted coffee, all inspired by the flavors and culture of the Bay Area .
