Coffee is a seasonal fruit and we source it directly from origin in freshly harvested lots. We practice small production methods that allow us to scrutinize and perfect our processes. Attaining a perfect roast is an intuition, a smell, a sound, a slight change in color— it’s about careful attention to detail that comes through in every cup.
Our company takes its name from the 'sightglass,' the viewing window on our vintage PROBAT coffee roaster that exposes the complex and delicate process of roasting coffee. We believe that 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 from the cup to the wider world.
Ultimately, we aim to deliver the highest quality achievable in all aspects of our business, whether that be sourcing the most beautiful and wondrous coffees attainable or employing the most mindful and quality-focused practices possible.

just behind a roll-up garage door housed in a sturdy 1914 built warehouse. People
and remarkably, even came back to taste more. Two years and many coffees later, the
warehouse would become our production roastery, a dynamic & unconventional coffee
gathering space, and our company headquarters.
