Understanding the coffee-to-water ratio is crucial for brewing an excellent cup of coffee. Each method has its ideal ratio that balances the extraction process, giving you a flavorful cup. Here's an overview of the ideal coffee-to-water ratios for each method:

  1. French Press:

    • Ratio: 1:12 to 1:15 (1 gram of coffee to 12–15 grams of water)
    • Details: French press requires coarsely ground coffee for optimal extraction. A 1:15 ratio is a common starting point, offering a balanced brew without being too strong or weak.
    • Example: For 30 grams of coffee, use 450 ml of water (at a 1:15 ratio).

  2. Pour-Over (e.g., V60 or Kalita Wave)

    • Ratio: 1:15 to 1:17 (1 gram of coffee to 15–17 grams of water)
    • Details: This method calls for a medium grind size, and the slower pour allows for nuanced flavors. The 1:16 ratio is a middle ground, but adjust to taste.
    • Example: For 20 grams of coffee, use 320 ml of water (at a 1:16 ratio).

  3. Aeropress

    • Ratio: 1:10 to 1:16 (1 gram of coffee to 10–16 grams of water)
    • Details: Aeropress is versatile, allowing for various grind sizes and brew times. A 1:16 ratio is a good starting point for a balanced cup.
    • Example: For 18 grams of coffee, use 270 ml of water (at a 1:15 ratio).

  4. Chemex

    • Ratio: 1:15 to 1:17 (1 gram of coffee to 15–17 grams of water)
    • Details: Chemex filters are thicker, which gives a cleaner cup with less sediment. Medium-coarse grind is preferred. Start with a 1:16 ratio, but adjust based on strength preferences.
    • Example: For 40 grams of coffee, use 640 ml of water (at a 1:16 ratio).

  5. Moka Pot

    • Ratio: 1:7 to 1:12 (1 gram of coffee to 7–12 grams of water)
    • Details: The Moka pot uses pressure to extract a rich, espresso-like coffee. A 1:10 ratio is common, offering a stronger flavor without over-extracting. The grind should be fine, but not as fine as for espresso.
    • Example: For 15 grams of coffee, use about 150 ml of water (at a 1:10 ratio).

Summary table:

Brewing Method Coffee-to-Water ratio Coffee grind size
French press 1:12 to 1:15 Coarse
Pour Over 1:15 to 1:17 Medium
Aeropress 1:10 to 1:16 Medium-fine
Chemex 1:15 to 1:17 Medium-coarse
Moka Pot 1:7 to 1:12 Medium-fine

These ratios are a starting point, and you can adjust them based on your taste preferences. The key is to experiment and find the ratio that gives you the perfect cup of coffee.
