Water Ratio
The proportion of coffee to water, usually expressed as ratio like 1:15 (1g coffee to 15g water). Determines concentration and strength.
How It Affects Your Coffee
📊 Extraction
Less water = higher concentration but also slower extraction (less liquid to dissolve into).
👅 Taste
Higher ratio (1:18) = lighter, clearer. Lower ratio (1:12) = stronger, fuller, richer.
🎯 Difficulty
Easy - just measure. But choosing right ratio for use case requires experience.
💡 Pro Tips
- •Standard range: 1:15 to 1:17 for filter coffee (black)
- •Stronger concentrate: 1:10 to 1:13 for milk drinks (lattes, cappuccinos)
- •Weaker/larger volume: 1:17 to 1:20 for light, tea-like coffee
- •Calculate: For 250ml cup, at 1:15 ratio = 250÷15 = 17g coffee
- •Start at 1:15 (17g coffee to 255g water) and adjust based on preference
- •Lower ratios can mask under-extraction, higher ratios expose it
⚠️ Common Mistakes
- ✗Using espresso ratios (1:2) for filter coffee - you get syrup
- ✗Using filter ratios (1:16) for milk drinks - coffee gets lost in milk
- ✗Not weighing water - "1 cup" varies from 200-300ml
- ✗Thinking ratio determines extraction - it determines concentration, not extraction level
- ✗Using very high ratios (1:20+) and wondering why coffee tastes sour - you need more coffee
⚙️ Equipment-Specific Advice
☕ Aeropress
1:14 to 1:17. Lower ratios for concentrate/milk drinks. Higher for americano-style.
🥃 French Press
1:13 to 1:16. Lower end is traditional. Use scale to measure - French Press markers are inaccurate.
🫗 Pour Over
1:15 to 1:17. Higher ratios (more water) help achieve desired brew time with right grind.
