Sightglass coffee roasters believe knowing the story behind your coffee—where it was grown, how it was processed, and who handled it along the way—is a powerful link between the cup and the wider world. Sightglass adopts a perfectionist attitude when it comes to the meticulous analysis and development of their product. They have taken a holistic approach in direct sourcing seasonal coffees, roasting to perfection out of San Francisco, California, since 2009.
