Coarse-ground, low-acid, and built for the overnight steep.
Published October 3, 2026
Cold brew is one of the most forgiving brewing methods — but the coffee you use still matters. The cold extraction process works differently than hot brewing. It pulls different compounds from the bean, which is why cold brew tends to be smoother, less acidic, and naturally sweeter than hot coffee made from the same beans.
This guide covers what makes a coffee good for cold brew, the best roast levels and grind sizes, how to get the ratio right, and the best coffees to use.
Cold brew extracts differently than hot brewing. The cold water pulls fewer acids and more of the smooth, chocolatey, and sweet compounds from the bean. This means coffees that are naturally low-acid and full-bodied tend to shine in cold brew. Dark and medium-dark roasts are the most popular choice — they produce a rich, smooth concentrate. Medium roast works well too. Light roast cold brew is possible but produces a thinner, more acidic result.
Use a coarse grind — similar to what you'd use for a French press. A coarse grind prevents over-extraction during the long steep time and makes filtering easier. Fine or medium grinds will over-extract and produce a bitter, muddy cold brew.
A standard cold brew concentrate ratio is 1:4 (1 cup of coarsely ground coffee to 4 cups of cold water). For a ready-to-drink cold brew (not concentrate), use 1:8. Adjust to taste — cold brew is forgiving and you can dilute concentrate with water or milk after brewing.
Steep cold brew in the refrigerator for 12–24 hours. 12 hours produces a lighter result; 18–24 hours produces a stronger concentrate. Do not steep at room temperature for more than 12 hours — refrigerator steeping is safer and produces a cleaner flavor.
Cold brew concentrate (1:4 ratio) is diluted before drinking — typically 1:1 with water or milk. Ready-to-drink cold brew (1:8 ratio) can be consumed straight. Concentrate is more efficient to store and lets you control strength at serving time.
Whole bean coffee ground fresh immediately before brewing will produce the best cold brew. Pre-ground coffee works fine — just make sure it's a coarse grind. Avoid pre-ground coffee labeled for espresso or drip — it's too fine for cold brew.
