How to Make Cold Brew Coffee

What is Cold Brew

Cold brew is coffee brewed with cold or room-temperature water over 12-24 hours. The low temperature extracts sweetness and body while leaving behind much of the acidity and bitterness. The result is a smooth, naturally sweet concentrate that can be served over ice or diluted.

Ratio: Concentrate vs Ready-to-Drink

Cold brew is usually made as a concentrate and diluted to taste. Here are both approaches.

Step-by-Step

1. 01Coarsely grind your coffee (coarser than French press — think raw sugar).
2. 02Combine coffee and room-temperature or cold filtered water in a jar, pitcher, or cold brew maker.
3. 03Stir to ensure all grounds are saturated.
4. 04Cover and refrigerate for 12-18 hours (or room temp for 12 hours).
5. 05Strain through a fine-mesh sieve, then through a paper filter or cheesecloth for clarity.
6. 06Store concentrate in the fridge for up to 2 weeks. Dilute with water, milk, or ice to serve.

Best Beans for Cold Brew

Medium to dark roasts with chocolate, caramel, and nutty profiles work best for cold brew. The long extraction amplifies sweetness and body while the cold water suppresses brightness. Avoid very light roasts — they can taste grassy or sour when cold-brewed. Brazilian, Guatemalan, and Colombian beans are excellent choices.
