Two variables decide 90% of the result with a cuccumella: the grind and the coffee-to-water ratio. Get these right, and the rest follows on its own. This is the numbers page.
The grind: medium-coarse
The cuccumella works by gravity, so the grind needs to let water through without clogging. The rule:
- Right: medium-coarse, drip/filter-style. Grains you can clearly feel.
- Too fine (mistake #1): water struggles, drips painfully slowly, the cup comes out bitter and over-extracted.
- Too coarse: water passes through too quickly, coffee comes out weak and watery.
If you only have one reference point: coarser than espresso, similar to fine sea salt.
The coffee-to-water ratio
Starting point: 1:16 – 1:17 (1 gram of coffee for every 16–17 grams of water). This gives a balanced cup, full-bodied but not heavy. If you like it more intense, move toward 1:15; lighter, move toward 1:18.
Doses by size
| Size | Water | Coffee (~1:16) |
|---|---|---|
| 1 cup | 60 ml | ~4 g |
| 3 cups | 180 ml | ~11 g |
| 6 cups | 360 ml | ~22 g |
| 9 cups | 540 ml | ~33 g |
These are guidelines: weigh it the first few times, then go by eye once you’ve got the hang of it.
How to “dial in” your coffee
- Start at 1:16 with a medium-coarse grind.
- Bitter or dripping painfully slowly? Grind coarser.
- Weak or watery? Grind finer or increase the dose.
- Change one thing at a time, or you won’t know what actually worked.
