Four Barrel Coffee
Four Barrel is an independent, locally owned specialty coffee roastery. They operate a pair of cafes, and they're partners in The Mill. They directly source almost all of the coffee that they roast for themselves and their wholesale partners. Great coffee comes from third-generation farmers and mill-workers in Latin America, Indonesia, and East Africa, and that's where they go to find it, forging relationships that ensure quality of life for their producers, and high-quality coffee for their roastery in San Francisco. They want to improve the lives of people all up and down the coffee chain and they're old-fashioned... about roasting. They rely on highly trained people, not computers, to see through the intention of their roasting style, that highlights the intrinsic qualities of a coffee that drove them to buy it in the first place: cleanness, sweetness, acidity, complexity. They roast on a hulking beast of a vintage German roaster—one that was made to hold consistent heat and let air flow through in simple ways controlled by a human being.
