    Cold Brew Coffee Ratios

    Introduction

    Cold brew coffee is a favorite for its smooth, rich flavor and low acidity. But to make the perfect batch, you need to nail the right coffee-to-water ratio.

    This guide will help you master the art of cold brew ratios whether you’re measuring in cups, grams, or liters.

    Let’s get started!

    Cold Brew Coffee Ratios

    Cold brew coffee is beloved for its smooth, rich flavor and versatility, but the secret to a perfect batch lies in getting the coffee-to-water ratio just right. Understanding how to measure your ingredients—whether in cups, grams, or liters—can make all the difference.

    Cold Brew Ratio in Cups

    For those who prefer measuring in cups, the standard cold brew ratio is 1 cup of coarsely ground coffee beans to 4 cups of water. This ratio produces a strong, full-bodied cold brew concentrate that’s perfect for diluting with water, milk, or ice.

    If you prefer a milder flavor, you can adjust the ratio to 1/2 cup of coffee beans for every 8 cups of water. This creates a lighter brew that’s still delicious and refreshing.

    Pro Tip: Always use coarsely ground coffee to avoid over-extraction and a bitter taste.

    Cold Brew Ratio in Grams

    For precision, measuring in grams is the way to go. A popular ratio is 1:8—1 gram of coffee for every 8 grams of water. This creates a balanced concentrate that you can dilute to your liking. For example, to make a liter of cold brew, you’ll need 125 grams of coffee.

    If you’re a fan of stronger brews, you can tighten the ratio to 1:4.5 (1 gram of coffee to 4.5 grams of water). This will give you a bold, intense flavor that’s perfect for coffee enthusiasts.

    Cold Brew Coffee Ratio for 1 Liter

    Making cold brew in liters? The ideal ratio is 1:12—1 part coffee to 12 parts water. For 1 liter of cold brew, you’ll need 83 grams of coarsely ground coffee. This ratio ensures a smooth, well-balanced brew that’s not too strong or too weak.

    If you’re making a larger batch, say 3 liters, simply scale up to 250 grams of coffee. Combine the grounds with water, stir gently, and let it steep for 12–24 hours in the fridge. Strain and your cold brew is ready to enjoy!

    Key Tips for Perfect Cold Brew

    1. Grind Size: Use a coarse grind, similar to coarse sand, to prevent over-extraction and sediment in your final brew.
    2. Steeping Time: Let your cold brew steep for 12–24 hours. The longer it steeps, the stronger the flavor.
    3. Dilution: Adjust the strength by diluting your cold brew concentrate with water, milk, or ice to suit your taste.
