21st Amendment Brewery opened their brewpub in 2000. In 2006 they started canning beer. After a long search, 21st Amendment started “partner brewing” with Cold Spring Brewing in Minnesota in 2008. The relationship has benefitted both companies very well.
Shaun O’Sullivan moved to the San Francisco Bay Area in the late 1990s and got a job at the storied Triple Rock Brewery. He met Nico Freccia who was writing for Celebrator magazine. But when they later met again in brewing classes at University of California, Davis, they decided to become partners on their own brewery.

21st Amendment doubled production from 2011 to 2012. Based on 2013 numbers, 21st Amendment was the 50th largest craft brewery in the nation.
And they’re coming home. Their new, hundred thousand-square-foot brewery in San Leandro, California will soon begin production.
Operations will continue in Minnesota. The partnership has been helpful to both companies. Each has learned from the other and each has grown significantly through the partnership.
“We call it partner brewing,” says Shaun. “We don’t like using the word ‘contract.’ We do have people out there. We have a lot of samples that are sent back and forth. It’s a huge amount of information that goes back and forth.”
“We don’t try to hide behind what we’re doing or what we’re not doing.”
With nearly 15 years of experience, Nicco has suggestions for a brewer wanting to start a brewpub:
- Raise more money.
- Consider your floor plan carefully.
- Find someone with business sense.
- Don’t stress out; be proud of what you did.
“There is a concern that there’s a bubble that’s going to burst, which I think is crap.” [Tweet This]
P.S. I found who said, “You can’t improve the beer, you can only keep it the same or hurt it. So your goal is to keep it the same when you’re putting it into packaging.” It was Rich Weber, in episode 019. I think it got cut out in post-production, but it was documented in episode 021.
