## How to Calculate Coffee-to-Water Ratio
### Standard Ratios
- **Drip / Pour-Over**: 1:16 (60 g per liter)
- **French Press**: 1:14 (70 g per liter)
- **AeroPress**: 1:12 (versatile, can be diluted)
- **Espresso**: 1:2 dose-to-yield (18 g in, 36 g out)
### Formula
**Coffee (g) = Water (mL) x Ratio per Liter / 1000 x Strength Factor**
One standard "cup" of coffee is 6 oz (177 mL). The SCA (Specialty Coffee Association) golden ratio is 55-65 g per liter.
### Grind Size Matters
The ratio assumes the correct grind for the method. Too fine = over-extraction (bitter). Too coarse = under-extraction (sour, thin).

Esempio Risolto
4 cups of drip coffee, standard strength.
- Water = 4 x 177 = 708 mL
- Coffee = 708 x 60 / 1000 = 42.5 g
- About 8.5 tablespoons of ground coffee
- Ratio = 1:16.7 water to coffee
