Ratios are coffee to water by weight. A scale makes this easy and repeatable; tablespoons are approximate because grounds vary in density (about 5 g per level tablespoon).

How to brew it

  • Grind: coarse.
  • Water temperature: cold or room temperature.
  • Brew time: 12–18 hours (room temp) or 16–24 (fridge).
  • Brewed at drinking strength, so you can pour it straight over ice.

Fixing the taste

Bitter, harsh, dryGrind a little coarser or brew shorter; or use less coffee (higher ratio number).
Fine but flatUse fresher beans, roasted within the last month, ground right before brewing.
