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

SizeWaterCoffee (~1:16)
1 cup60 ml~4 g
3 cups180 ml~11 g
6 cups360 ml~22 g
9 cups540 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.
