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: fine to medium.
- Water temperature: 175–205°F (80–96°C).
- Brew time: 1½–2 minutes.
- Add coffee and water, stir, steep about a minute, then press gently for 20–30 seconds. Lower temperatures make it sweeter.
Fixing the taste
| If it tastes… | Try this |
|---|---|
| Sour, thin, weak | Grind a little finer or brew longer; or use more coffee (lower ratio number). |
| Bitter, harsh, dry | Grind a little coarser or brew shorter; or use less coffee (higher ratio number). |
| Fine but flat | Use fresher beans, roasted within the last month, ground right before brewing. |
