21st Amendment Brewery sits on 2nd Street in SoMa, two blocks from Oracle Park, and has been a San Francisco beer institution since Nico Freccia and Shaun O'Sullivan opened it in 2000. The brewpub reopened in 2026 after a renovation, timed to the return of Giants baseball.
The address is 563 2nd Street, in the South Beach corner of SoMa that fills with ballgame crowds in season. The name nods to the constitutional amendment that ended Prohibition, and the room keeps that tavern-pride streak: a long bar, big tables built for groups, and walls that carry the brewery's 25-year history in the city.
What to order is the beer that made the brand. Brew Free! or Die IPA is the flagship and the pour to start with, followed by Hell or High Watermelon, the summer wheat beer that put 21st Amendment on grocery shelves nationwide, or Back in Black, the black IPA. Pints run in the single digits, and the kitchen turns out the burgers and shareable plates that a ballpark brewpub lives on.
Brewbound covered the brewpub's reopening as a celebration of "the return of SF Giants baseball", and the beer trade outlet New School Beer reported in April 2026 that "21st Amendment Brewery is back in business" after the refresh. The original 2nd Street pub is where the company started before it added its larger San Leandro production brewery, which is the editorial fact that grounds the place.
The best time to go depends on the schedule. On a Giants home day the room fills early and runs loud through first pitch, which is the experience to seek out or avoid depending on taste. On a non-game weeknight it settles into a neighbourhood brewpub, with the bar open from 11:30am daily and last call later on Friday and Saturday.
The crowd is a SoMa mix of ballgame fans, downtown workers and beer drinkers who have followed the brand since the early 2000s. It suits a pre-game pint, a group dinner over flights, or anyone working through the city's craft-beer history, and it is a poor fit for a quiet date night on a game day.
The appeal is a founding-era San Francisco brewpub that still pours its own beer a short walk from the ballpark. For more of the city, see the best bars in San Francisco and the roundup of craft beer in San Francisco, or browse the wider craft beer pillar.
