What is a Cold Brew Ratio Calculator?
A Cold Brew Ratio Calculator helps you determine the perfect amount of coffee grounds needed to make your desired volume of cold brew coffee. Cold brew uses a concentrated brewing method with a standard ratio of 1:4 (coffee to water), creating a smooth, less acidic coffee concentrate.
Formula
The formula for calculating coffee grounds needed is:
[\text{Coffee Grounds Needed} = \frac{\text{Total Cups of Coffee Desired}}{4}]
This represents the standard 1:4 coffee-to-water ratio commonly used for cold brew concentrate.
How to Use
- Enter the total cups of coffee you want to make
- Select your preferred unit (cups or milliliters)
- Click "Calculate" to see how much coffee grounds you need
Calculation Examples
Example 1: Making 8 Cups
- Total cups desired: 8 cups
- Coffee grounds needed: 8 ÷ 4 = 2 cups of grounds
Example 2: Making 3 Liters
- Total volume desired: 3 liters
- Coffee grounds needed: 3 ÷ 4 = 0.75 liters of grounds
Cold Brew Coffee Tips
Steeping Time: Cold brew typically steeps for 12-24 hours in the refrigerator. Longer steeping creates stronger concentrate.
Grind Size: Use coarse ground coffee for best results. Fine grounds can make the coffee bitter and harder to filter.
Concentrate vs Ready-to-Drink: The 1:4 ratio produces a concentrate. When serving, dilute with equal parts water or milk to taste.
Storage: Cold brew concentrate can be stored in the refrigerator for up to 2 weeks in an airtight container.
Why Cold Brew?
Cold brew coffee offers several advantages:
- Less Acidic: Cold water extraction produces up to 67% less acid than hot brewing
- Smooth Flavor: The slow process creates a naturally sweeter, smoother taste
- Convenience: Make a batch once and enjoy it throughout the week
- Versatility: Use as a base for iced coffee, lattes, or coffee cocktails
