Brewing Methods and Their Ratios

Brewing Method	Coffee:Water Ratio	Notes
Ristretto	1:1.5	Concentrated espresso variant
Espresso	1:2 (use 1:3.6)*	Standard espresso shot
Lungo	1:3	Extended espresso shot
Cold Brew	9:40	12-24 hour steeping time
Moka Pot	1:10	Stovetop coffee maker
Aeropress	1:11	Single-cup brewing
French Press	1:12	Full-immersion brewing
V60	3:50	Pour-over method
Chemex	1:17	Pour-over with thicker filter

*Note: For espresso, use a 1:3.6 ratio to achieve a 1:2 final ratio due to water absorption by coffee grounds.

How to Use the Calculator

1. Select your brewing method
2. Enter your desired final coffee volume
3. The calculator will provide:
   • Amount of ground coffee needed
   • Amount of water required
   • Expected final volume

Understanding Coffee Measurements

• 1 gram of coffee ≈ 1 ml in volume
• 1 coffee bean ≈ 0.13 grams
• Water loss varies by brewing method:
  • Espresso: ~80% absorption by grounds
  • Pour-over: ~20% retention
  • French press: ~10% retention

Tips for Perfect Coffee

1. Use Fresh Coffee

   • Grind just before brewing
   • Store beans in an airtight container

2. Water Temperature

   • Most methods: 195-205°F (90-96°C)
   • Cold brew: Room temperature or cold

3. Grind Size

   • Espresso: Fine
   • Pour-over: Medium-fine
   • French press: Coarse
   • Cold brew: Extra coarse

4. Measuring Tools

   • Use a digital scale for accuracy
   • Measure water by weight when possible
   • Consider investing in a gooseneck kettle for pour-over methods

Common Issues and Solutions

1. Too Strong

   • Increase water ratio
   • Check water temperature
   • Adjust grind size

2. Too Weak

   • Decrease water ratio
   • Ensure proper water temperature
   • Check grind size

3. Bitter Taste

   • Coarsen grind
   • Reduce brewing time
   • Check water temperature

4. Sour Taste

   • Finer grind
   • Increase brewing time
   • Verify water temperature
