Why Cold Brew Coffee Ratios Matter

Cold brew isn’t just iced coffee — it’s a unique brewing method that involves steeping coffee grounds in cold or room-temperature water for 12–24 hours. The result is a smoother, less acidic, and often more caffeinated coffee experience.

But here’s the catch: the ratio of coffee to water makes all the difference. Using the wrong cold brew ratio can leave you with a brew that’s too weak, overly strong, or simply off in flavor.

Brew Like a Pro With the Right Cold Brew Ratio

There are two key ratios to understand:

  • Brewing Ratio (Coffee:Water) – The ratio used to make your cold brew concentrate.
  • Dilution Ratio (Concentrate:Water) – The ratio used to turn concentrate into a drinkable cup.

Common cold brew coffee ratios include:

  • 1:4 or 1:5 – Strong concentrate, ideal for later dilution
  • 1:7 to 1:10 – Balanced and versatile
  • 1:12+ – Ready-to-drink strength, light and refreshing

Our cold brew ratio calculator helps you:

  • Choose the right strength for your taste
  • Calculate exactly how much coffee and water to use
  • Account for water absorption during steeping
  • Get guidance on steep time, grind size, and more
