Best Coffee for Cold Brew: Beans, Ratios & Recipe
Cold brew does not need one special roast. Choose a coffee you like, then use the right ratio for a ready-to-drink batch or a concentrate and adjust the finished glass to your taste.

The best coffee for cold brew is one you want to drink cold. There is no required dark roast or secret bag. Choose a flavor direction, then decide whether you want a ready-to-drink batch or a concentrate you will dilute.
What coffee works for cold brew?
A coarse grind helps with filtering after a long steep. Roast is a preference, not a rule: a deeper coffee can stay noticeable with milk, while a coffee with brighter listed notes may be more interesting served black. Start with a coffee you already like before buying something solely because the package says cold brew.
For a deeper, spice-and-citrus direction, The Mandheling is an active medium-dark Sumatran coffee with black tea, brown spice and citrus notes. Its current grind options include Coarse for cold brew. Those notes are descriptions of the plain coffee, not ingredients added to it.
Two cold-brew ratios to start with
Ready to drink: 60 g coarsely ground coffee with 900 g cold drinking water, a 1:15 starting ratio. Filter after steeping, then serve as is or over a little ice.
Concentrate: 100 g coarsely ground coffee with 500 g water, a 1:5 starting ratio. Filter it, then begin with roughly one part concentrate to one part water or milk in the glass and adjust to taste. This is a stronger base intended for dilution, not the same serving as the ready-to-drink version.
- Combine grounds and water in a clean covered vessel. Stir until all grounds are wet.
- Steep covered in the refrigerator for about 12–18 hours as a starting window. Taste and adjust the next batch for your coffee and grind.
- Filter thoroughly with a fine strainer and, if needed, a paper filter. Keep the finished coffee covered and refrigerated.
How do you fix a cold brew that is too strong?
First taste it before adding anything. If you made concentrate, dilute a serving rather than discarding the batch. If a ready-to-drink brew seems heavy, add a little water or milk in the glass. Ice will also dilute it as it melts. Write down the final ratio you liked so you can begin closer to it next time.
If the next batch tastes harsh or muddy, look at grind and steep time before changing roast. A finer grind can leave more sediment and make filtering harder. Keep the vessel and filter clean, brew manageable amounts, and do not assume a homemade batch has a guaranteed storage life.
Cold brew is not iced coffee
Cold brew steeps in cool water over hours. Iced coffee is brewed hot and cooled for serving over ice. Both can be good, but the same beans can taste different prepared those two ways. The method does not, by itself, tell you the caffeine in a finished glass; coffee amount and dilution change the serving.
If you have extra beans between batches, our coffee storage guide keeps the routine simple. For a flavored variation, see the pumpkin-spice cold-brew recipe.
