| Brewing Method | Ratio (Coffee:Water) | Example | Strength |
|---|---|---|---|
| Espresso | 1:2 | 18g → 36g (36ml) | Very Strong |
| Moka Pot | 1:10 | 30g → 300ml | Strong |
| AeroPress | 1:15 | 17g → 255ml | Medium-Strong |
| Drip Coffee | 1:16 | 25g → 400ml | Medium |
| Pour Over | 1:16 to 1:17 | 20g → 320-340ml | Medium |
| French Press | 1:15 to 1:17 | 30g → 450-510ml | Medium |
| Cold Brew | 1:8 (concentrate) | 100g → 800ml | Concentrate |
The "Golden Ratio" for coffee is 1:16 to 1:18 (1 gram of coffee to 16-18 grams/ml of water). This is considered the ideal balance for drip coffee and pour-over methods, producing a well-extracted, balanced cup.
Espresso (1:2) and Moka Pot (1:10) use higher coffee-to-water ratios because pressure extracts more efficiently. Less water is needed to achieve full flavor.
French Press (1:15) and Cold Brew (1:8) need longer contact time. Ratios are adjusted to prevent over or under-extraction.
Drip (1:16) and Pour Over (1:16-17) use the "golden ratio" for balanced extraction through paper filters.
Cold Brew (1:8) creates a concentrate that's diluted 1:1 with water or milk before drinking.
| 1 tablespoon | ≈ 5 grams |
| 1 coffee scoop | ≈ 7 grams |
| 2 tablespoons | ≈ 10 grams |
| 1/4 cup | ≈ 20 grams |
| 1/3 cup | ≈ 27 grams |
| 1 fluid ounce (oz) | ≈ 30 ml |
| 1 cup (US) | ≈ 240 ml |
| 1 mug | ≈ 350 ml |
| 1 liter | ≈ 33.8 oz |
| 1 gallon | ≈ 3.8 liters |
The ideal ratio for moka pot is 1:10 (1g coffee to 10ml water). For a 6-cup moka pot, use 30g of coffee with 300ml of water.
The "golden ratio" is 1:16 to 1:18, meaning 1 gram of coffee for every 16-18 grams (ml) of water. This produces a balanced, well-extracted cup for drip and pour-over methods.
For a standard 8oz (240ml) cup, use 2 tablespoons (10g) of ground coffee. This follows approximately the 1:16 golden ratio.
Water temperature doesn't change the ratio, but it affects extraction. Use 195-205°F (90-96°C) for most methods. The ratio stays the same regardless of temperature.
Dark roasts are more porous and extract faster, so you might use slightly less coffee (1:17 instead of 1:16). Light roasts can handle more coffee (1:15) for full extraction.
