Geometry from Onyx

Onyx · Colombia + Ethiopia - Washed

Grind: #10-14 espresso · Water: 205°F · Onyx recommends 20:45 at 24-26 seconds

Fruit, tea like.

First pull of Onyx coffee. Expectations are high. High profile coffee roaster from Arkansas.

  • First pull at 14 poured through at 18 seconds. This was a sour pull I tossed. 36g
  • Second was 11, came out at 25 seconds. 36g
  • Third was 10 at 30 seconds. 36g

Still sour. See, Onyx recommends a 20:45 ratio which is much longer than I was pulling.
