Coffee to Water Ratio
The Golden Ratio: 1 gram of coffee per 15–17 grams of water (1:15 to 1:17)
Each brew method has its own ideal ratio:
| Method | Ratio | Flavor Profile |
|---|---|---|
| Pour Over (V60) | 1:15 – 1:17 | Clean, bright, nuanced |
| French Press | 1:12 – 1:15 | Full-bodied, bold |
| Drip Machine | 1:15 – 1:18 | Balanced, everyday |
| AeroPress | 1:10 – 1:15 | Concentrated, versatile |
| Cold Brew | 1:4 – 1:8 | Concentrate for dilution |
| Espresso | 1:2 – 1:3 | Intense, syrupy |
The Specialty Coffee Association (SCA) recommends a ratio of 1:18 for filter coffee.
