Four Barrel Coffee

Four Barrel Coffee, founded in San Francisco's Mission District in 2008, built its identity around a specific kind of stubbornness: the company says it relies on 'highly trained people, not computers' to roast, on what it calls 'a hulking beast of a vintage German roaster' from 1957. That equipment choice runs through the rest of the operation -- Four Barrel says it directly sources almost all of its coffee, spending months of every year traveling to origin in Latin America, Indonesia and East Africa to build relationships with the farmers and mill workers who grow and process it, rather than buying through intermediaries. The company has grown from its original Valencia Street roastery to operate two cafes plus a stake in The Mill, a well-known Divisadero Street bakery-café partnership. Community investment extends past the supply chain, too: Four Barrel has backed a 900-person co-op school project in Ethiopia, one of the countries it sources beans from. The roasting philosophy stays consistent across all of it -- cleanness, sweetness, acidity and complexity in the cup, chased by hand rather than by preset roast curves, on a machine old enough that keeping it running is itself part of the craft the company sells alongside the coffee.
