How do I choose coffee for a cold brew press?

Using a cold brew press is a fantastic way to make high-quality coffee at home. Because the press uses an immersion method—where the coffee grounds are fully submerged in water for an extended period—it is very forgiving. When choosing beans, you want to focus on roasts that offer a balanced, sweet, and rich profile. Medium to dark roasts are ideal because they have the body and depth to stand up to the long, cold extraction time.

Dark roasts are particularly popular for cold brew presses because they produce a bold, chocolatey, and low-acid cup. If you prefer something a bit more nuanced, a medium roast will offer a balance of sweetness and acidity, with subtle fruit or floral notes. Avoid very light roasts unless you are prepared for a longer steep time, as they can sometimes taste thin or overly acidic when brewed cold.

Grind size is the most important technical detail. You must use a coarse grind, similar to the texture of sea salt. If your grind is too fine, the press's mesh filter will not be able to catch all the fine particles, leading to a gritty, muddy cup. Furthermore, a fine grind will over-extract during the long steep, resulting in an unpleasantly bitter and astringent flavor. A coarse grind ensures a clean, smooth, and delicious concentrate.

In practice, start with a coffee that you enjoy as a hot brew. If you find the result too intense, you can dilute it with water or milk. If it's too weak, try a slightly longer steep time or a slightly higher coffee-to-water ratio. The beauty of the cold brew press is its simplicity; once you find the right bean and grind, you can easily replicate your perfect cup every time.
