Pour Over Coffee Ratio Calculator

Brewing coffee is both an art and a science. For many coffee enthusiasts, the pour-over method is the gold standard for achieving a clean, flavorful cup. However, the biggest challenge lies in maintaining the perfect coffee-to-water ratio. Using too much coffee can make your brew bitter, while too little may leave it watery and weak.

That’s where the Pour Over Coffee Ratio Calculator comes in. This easy-to-use tool helps you determine the ideal amount of coffee and water for your chosen brewing method. Whether you’re a beginner learning the basics or an expert experimenting with ratios, this calculator ensures consistency and precision in every cup.

How to Use the Pour Over Coffee Ratio Calculator

Using the calculator is straightforward and beginner-friendly. Here’s a step-by-step guide:

1. Select Your Brew Method
   Choose your brewing style (V60, Chemex, Kalita, Melitta, AeroPress, or a custom method). Each has slight variations in brewing techniques and ratios.
2. Pick a Ratio
   Select a preset water-to-coffee ratio (15:1 for strong, 16:1 for medium, 17:1 for standard, or 18:1 for light). You can also enter a custom ratio if you prefer.
3. Enter Brew Size or Coffee Amount
   • If measuring by water amount, input the total volume of water you plan to use.
   • If measuring by coffee amount, input the grams of coffee you want to brew with.
4. Click Calculate
   The calculator will process your inputs and display the precise coffee or water required, along with an approximate yield.
5. Check Your Results
   You’ll see the ideal brew method, ratio used, water required, coffee required, and the estimated yield in milliliters, ounces, and cups.
6. Optional Actions
   • Copy results to save your recipe.
   • Share results with a friend or on social media.
   • Reset if you want to start over.

Example: Brewing with a V60

Imagine you want to brew a medium-strength cup using a V60 with 300ml of water:

• Select V60 as the brew method.
• Choose 16:1 (medium) ratio.
• Enter 300ml water as the brew size.
• Click Calculate.

The calculator will display:

• Coffee Required: ~18.8g (0.66 oz)
• Water Required: 300ml (10.1 oz)
• Yield: ~262ml (8.9 oz, about 1.1 cups)

This ensures your coffee is balanced—neither too strong nor too weak.
