“This was nice but also nothing special. I’m wonder if I developed this roast this little bit darker if it will become more flavorful.”

Cup quality across 7 attempts

Each point is a roast scored from tasting notes (1 = miss, 5 = dialed in). The series stops at the teal halo — once dialed in, later repeats aren’t scored the same way.

Where the good cups live

Roast level vs batch size. Color = profile family; larger dots = better cups. Notice how quality clusters once batch size moves to 100–120g.

What the data taught us

  1. 1This washed Honduras has been stubborn — early F-WSH 1000-1700 cups were bland, grassy, or sour without sweetness.
  2. 2Pushing level alone (2.0 → 3.0) reduced green but never unlocked a clear cup profile.
  3. 3Best so far: NCT Filter D at 3.0 / 120g (R-088) — “nice but nothing special”; R-098 at 3.2 is the darker experiment.
  4. 4Still dialing for sweetness/body rather than a finished origin-clarity win.
Roast goal: Aim for a balanced medium roast that develops the caramel sweetness and roasted almond body while preserving the subtle starfruit note. Avoid going too light where acidity might dominate without enough sweetness to balance, and avoid dark where the caramel becomes ashy and the delicate fruit is lost.
