Coffee-to-water ratios, grind size and water temperature for seven brewing methods. All ratios by weight (grams) for consistency. Pin to the kitchen wall or keep with your coffee gear.
| Method | Ratio (coffee:water) | Example (300 ml cup) | Grind size | Water temp | Brew time |
|---|---|---|---|---|---|
| Espresso | 1:2 (by yield) | 18 g in → 36 g out | Extra fine | 92–96°C / 198–205°F | 25–30 s |
| Moka pot | 1:7 to 1:10 | Fill basket level | Fine (not espresso) | Cold water start | 5–8 min |
| AeroPress (espresso style) | 1:6 to 1:10 | 15 g + 90–150 ml | Fine to medium-fine | 80–96°C / 176–205°F | 1–2 min |
| AeroPress (filter style) | 1:12 to 1:16 | 19 g + 240 ml | Medium | 85–96°C / 185–205°F | 1.5–3 min |
| Pour over (V60, Kalita, Chemex) | 1:15 to 1:16 | 20 g + 300 ml | Medium | 92–96°C / 198–205°F | 3–4 min |
| French press | 1:15 to 1:17 | 20 g + 300 ml | Coarse | 93–96°C / 200–205°F | 4 min steep |
| Drip / filter machine (SCA) | 1:15 to 1:18 | 17 g + 300 ml | Medium | 90–96°C / 194–205°F | 5–8 min |
| Cold brew (concentrate) | 1:4 to 1:5 | 75 g + 300 ml | Coarse | Cold / room temp | 12–24 h |
| Cold brew (direct / ready to drink) | 1:8 | 38 g + 300 ml | Coarse | Cold / room temp | 12–24 h |
Espresso ratio is measured as input coffee to output liquid espresso (yield), not water used. The machine uses roughly 35–45 ml of water to produce 36 g of espresso. Water temp for moka pot: always start with cold water; it heats up during brewing.
| Grind size | Feel | Methods that use it |
|---|---|---|
| Extra fine | Like powdered sugar / flour | Espresso (commercial), Turkish coffee |
| Fine | Like table salt | Espresso (home), moka pot, AeroPress short |
| Medium-fine | Like fine sand | Pour over (V60), AeroPress filter |
| Medium | Like beach sand | Drip machine, Kalita Wave, Chemex, AeroPress |
| Coarse | Like raw sugar / sea salt | French press, cold brew, percolator |
| Extra coarse | Like coarse ground pepper | Cold brew (long steep), Cowboy coffee |
| Coffee (g) | Water (ml) | Water (ml) at 1:17 | Cup size |
|---|---|---|---|
| 10 g | 150 ml | 170 ml | Small / ristretto-style |
| 15 g | 225 ml | 255 ml | Standard single cup |
| 20 g | 300 ml | 340 ml | Large cup / travel mug |
| 30 g | 450 ml | 510 ml | Two cups / large press |
| 55 g | 825 ml | 935 ml | Full 1 L French press |
| 65 g | 975 ml | 1,105 ml | Full 1 L Chemex |
