Sightglass is an independent, sibling-owned coffee company in San Francisco. The company takes its name from the 'sightglass,' the viewing window on the vintage PROBAT coffee roaster that exposes the complex and delicate process of roasting coffee. Here you'll have house-roasted beans served along with baked goods in a bi-level, industrial space.
Sightglass began in 2009 with a small, rickety service cart in SoMa district. Equipped with a few Chemex pots and a leaky vintage 2-group espresso machine, Sightglass served coffee to the neighborhood just behind a roll-up garage door housed in a sturdy 1914 built warehouse. People came to visit them, and remarkably, even came back to taste more.
A few years and many coffees later, the entirety of the warehouse became the production roastery, a dynamic & unconventional coffee bar, a community gathering space, and the company headquarters.
