How to Brew Cold Brew Coffee at Home with a Bundle

Quick Answer

For a smooth, low-bitter cold brew at home, use a coarse grind, a 1:8 coffee-to-water ratio, steep for 12–24 hours at room temperature or in the fridge, then filter. A bundle of beans chosen for cold brewing saves guesswork and delivers consistent results.

Step-by-Step Cold Brew Instructions

1. 1. Grind and Measure: Weigh your coffee beans and grind them on the coarsest setting (like breadcrumbs). Use a 1:8 ratio by weight—for example, 100g coffee to 800g water. A common mistake is grinding too fine, which leads to over-extraction and bitter, muddy cold brew. If you don't have a scale, use 1 cup of coarse grounds to 4 cups of water, but weight is far more consistent.
2. 2. Combine and Steep: Place the grounds in a large jar or pitcher, add cool filtered water, and stir gently to saturate. Cover and let it steep at room temperature for 12–24 hours, or in the fridge for 18–24 hours. A checkpoint: steeping longer than 24 hours can make the brew taste woody or over-extracted, especially with very dark roasts. Start checking flavor at 12 hours; if it tastes weak, let it go longer.
3. 3. Filter and Store: Pour the steeped mixture through a fine-mesh sieve lined with a paper filter or a nut milk bag into a clean container. Press gently on the grounds—do not squeeze, as that forces bitter sediment through. Store the filtered concentrate in the fridge for up to 2 weeks. Common mistake: skipping the paper filter leaves a silty texture. Dilute the concentrate with equal parts water or milk before drinking, or adjust to taste.
