How to Calculate Cold Brew Ratio

Common Ratios (Coffee : Water by weight)

  • 1:6 - Concentrate. Dilute 1:1 with water, milk, or ice before serving. Bold, strong flavor.
  • 1:12 - Ready to drink. No dilution needed. Balanced strength.
  • 1:15 - Light and refreshing. Good for iced coffee on hot days.

    • Steeping

    Steep ground coffee in cold or room-temperature water for 12-24 hours. Most recipes recommend 16-18 hours. Longer steeping increases extraction but can also increase bitterness.

    Grind Size

    Use a coarse grind (similar to French press). Fine grinds will over-extract and make the cold brew harsh and gritty.

    Exemple Résolu

    1 liter of cold brew concentrate (1:6 ratio), 18-hour steep.

    1. Coffee = 1000 / 6 = 167 g (about 2 cups)
    2. Water = 1000 mL
    3. Steep for 18 hours in the refrigerator
    4. Strain and dilute 1:1 for 8 servings of 240 mL each.
