Batch 214 / Guji, Ethiopia / dropped at 11:42

Roasted to the second.

We roast in small batches on a 15 kg drum and log every curve. When a coffee tastes its best at 11 minutes 42 seconds, that is when it leaves the drum. Not a moment later.

On the shelf this week

Three coffees, each roasted the way it wants to taste.

We buy directly from the farms below and roast every Tuesday and Friday. Bags ship within 48 hours of roasting.

How a batch is roasted

Eleven minutes, forty-two seconds.

Every coffee gets its own profile. Here is what happens inside the drum, minute by minute.

  1. 0:00

    Charge

    Green beans drop into a drum preheated to 205 °C. Their temperature falls fast as the cold beans soak up heat.

  2. 1:28 to 4:50

    Drying

    Moisture leaves the bean and the color turns from green to straw yellow. The air smells like fresh bread.

  3. 4:50 to 9:31

    Browning

    Sugars and amino acids react and build sweetness and body. We lower the gas here so the flavor develops evenly.

  4. 9:31 to 11:42

    First crack

    The beans pop like popcorn. From here, every ten seconds changes the cup, so we taste-test and drop on the mark.

  5. +48 hours

    Rest and cup

    The coffee rests for two days, then we cup it blind. If it misses the profile, it does not ship.
