Inside a Coffee Roastery: From Green Beans to the Cupping Table

Before coffee is a drink, it’s a seed in a burlap sack. A working roastery is where that seed becomes the thing you taste — and it’s more lab than kitchen in there.

Green coffee storage

Green beans arrive by the sack and get sorted into bins by origin and lot. Unroasted coffee smells like grass and grain — nothing like what comes out of the roaster.

The roaster

The machine itself is deceptively simple — a rotating drum, a heat source, a cooling tray. The skill is in the curve: when to push heat, when to let it ride, when to drop the batch. Every decision shows up in the cup weeks later.

The lab

The long table is where production gets judged — rows of glasses, flights of samples, everything tasted blind against the last batch.

Spoons moving in unison. It’s the same cupping ritual you’d see at a festival, except here it’s not a show — it’s quality control. This is how a roastery keeps Tuesday’s batch honest.
