21st Amendment Brewery & Restaurant opened in 2000, and began canning their beer by hand in 2006. The popularity of their beer in cans far outpaced their ability to keep making it on-site, and production was moved to the Cold Spring Brewery in Minnesota to meet demand. But that will soon be changing, as the San Francisco brewpub has announced that they will be building a new production brewery right here in the Bay Area, with plans for the new facility to open later this year.

The new brewery will be located in the East Bay, in San Leandro, at 2010 Williams Street. In addition to a production brewery, the new space will also include a restaurant and tasting room, as well. The new facility is 95,000 square feet and will accommodate an “initial brewing capacity of 100,000 barrels, scalable to over 250,000, making it among the largest breweries in the Bay Area.” Estimated volume for 2014 is over 70,000 barrels. The building used to house a Kellogg Cereal factory.

From the press release:

“Since we began packaging our beer six years ago with our Minnesota partner brewery, we have never been able to keep up with demand,” said co-founder Nico Freccia. “Building our own local brewery will allow us to continue to focus on improving quality and consistency, and to expand into new markets where our beer is in demand.”

“We look at this as an opportunity for us to bring the vision and beer home to the Bay Area where it all started when we opened our San Francisco brewpub in 2000,” added co-founder and Brewmaster Shaun O’Sullivan. “This will allow us to continue to deepen our SF Bay Area local roots and to keep having fun making great beer. Both Nico and I are excited about making more interesting beers with our unique packaging that craft beer drinkers have come to know and love. It’s every brewer’s dream to open their own brewery and this is truly a dream come true for us.”

In addition to a state-of-the-art craft brewing facility, the new location, where Pop-Tarts and Frosted Flakes were once produced, will feature a tasting room and retail area as well as the company’s world office headquarters. Phase two will commence in 2015 and will include a full restaurant/pub, beer garden, event and meeting rooms and more. The company expects to create 20 new jobs over the next nine months and a hundred jobs over five years.

“This project will be nothing short of the number one destination spot for craft beer aficionados and beer lovers near and far. With an interactive space that will enhance each guest’s experience as they adventure around the production brewery, the plans are to repurpose the historical cereal factory in a way that celebrates the building’s industrial character and blurs the boundaries between the production space and the hospitality space,” said lead designer David Darling, of San Francisco architects Aidlin Darling Design.

The new brewhouse will be a 100-barrel, four-vessel GEA/Huppmann, “with an initial capacity of eight brews per day.” The brewery will also include a new “state of the art KHS high speed volumetric can filling line that will be capable of filling up to 500 cans per minute.”
