Overview

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.

Sourcing

Sourcing green coffee is at the heart of what we do at Sightglass. It is meticulous and essential work. Processing methods, varieties, growing altitudes, climate, soil and farm conditions are a few of the many factors that shape and determine a coffee’s overall quality. Being present at origin allows us to see these factors first hand and ultimately, helps us determine the best expression of each coffee we work with.

Roasting

Roasting is the transformation of green coffee from a raw product into something that will be consumed. We view roasting as one piece of the larger collaboration between our farmers, sourcing partners, and finally baristas and home brewers. Our objective as a coffee roasting company is to recognize the intentions of the people who have contributed to producing our coffees and express these intentions through our work.
