San Francisco encompasses a land area of about 46.9 square miles (121 km²) on the northern end of the San Francisco Peninsula, which makes it the smallest county in the state. It has a density of about 18,187 people per square mile (7,022 people per km²), making it the most densely settled large city (population greater than 200,000) in the state of California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego and San Jose, and the 13th-most populous city in the United States—with a Census-estimated 2014 population of 852,469. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.6 million.

21st Amendment Brewery

21st Amendment Brewery is a restaurant and brewery located in the South Park neighborhood of San Francisco, California, two blocks from AT&T Park. The brewery's name refers to the 21st Amendment to the U.S. Constitution, which ended Prohibition.

History

The brewery was founded in 2000 by Nico Freccia and Shaun O’Sullivan. O’Sullivan had previously worked as an assistant brewer at Triple Rock Brewery & Alehouse in Berkeley.

The San Francisco Business Times wrote that it "made a name for itself as a local brewery and restaurant where SoMa techies could lunch and Giants fans could gather before a game." It has been voted "Best Brewpub", "Best Burger" and "Best Happy Hour" by the San Francisco Press.

Prior to 2015, 21st Amendment's retail beers were canned in Cold Spring, Minnesota. In 2012, 21st Amendment planned to case 45,000 barrels of beer, up from 28,000 in 2011. In 2014, plans were announced to open a production facility and tasting room in San Leandro, California. That year, the company was the fiftieth top selling craft brewery in the US.
