a roast is a pressure reading.
We do not chase a profile. We listen for a moment in the bean's surface tension where sweetness sets and acid stays bright. We log it. We repeat it.
Every batch is roasted in 3-kg flights, drum temperature monitored to 0.1 °C, airflow plotted against bean mass loss. The result is a pressure reading: a number, a curve, a memory.
- 01 green is rested 21 days minimum after arrival.
- 02 first crack is the surface; second crack is the abyss.
- 03 we cup blind, on the eighth day post-roast.
- 04 a profile only ships once it scores above 86.

Cupping the new Yirgacheffe arrival
Eighth-day blind cup. The lot held its bergamot through cooling and lifted at 24 °C. We logged 87.5.

A note on grinder burr geometry
Conical against flat: an old argument. We measured particle distribution at 600 µm across both. Conical pulled 11% more sweetness on this Huila.

Buoyancy: brewing for sea-level vs. mountain
Atmospheric pressure changes extraction more than any of our roast variables. Three altitudes, one bean.

Why we don't use kraft bags
Light is the enemy of staling, but oxygen is louder. We chose foil + valve. We chose the abyss.
