How to Find the Perfect Coffee to Water Ratio
The coffee-to-water ratio is one of the most important factors in brewing great coffee. The Specialty Coffee Association recommends a 1:16 ratio (1 gram of coffee to 16 grams of water) as a starting point.
Different brew methods require different ratios:
- Drip Coffee: 1:16 to 1:18 — produces a clean, balanced cup
- French Press: 1:14 to 1:16 — fuller body, more oils
- Pour Over: 1:15 to 1:17 — bright and clean flavours
- Espresso: 1:2 to 1:3 — concentrated and intense
- AeroPress: 1:10 to 1:15 — versatile, depending on recipe
- Cold Brew: 1:8 to 1:10 — smooth and less acidic

Tips for Better Coffee

- Grind just before brewing: Pre-ground coffee loses flavour quickly.
- Use filtered water: Mineral content affects extraction.
- Water temperature: 90-96°C (195-205°F) is ideal for most brew methods.
