Cold brew trades heat for time, steeping coarsely ground coffee in cold water for many hours instead of minutes. The result is a smooth, naturally sweet, low-acid concentrate that's as versatile served over ice as it is diluted with hot water.
Quick Answer
Cold brew coffee is made by steeping coarsely ground coffee in cold or room-temperature water for 12-24 hours, then straining to produce a concentrate, typically at a 1:8 ratio, that's diluted with water, milk, or ice before drinking.
What You'll Need
A large jar or dedicated cold brew maker, a coarse grind of coffee — coarser than French press — cold or room-temperature water, and a fine strainer or paper filter for the final straining step.
Step-by-Step Method
| Step | Instructions |
|---|---|
| 1. Combine | Combine coffee and water at roughly 1:8 ratio in a jar |
| 2. Stir | Stir gently to fully saturate the grounds |
| 3. Steep | Cover and steep at room temperature or in the fridge for 12-24 hours |
| 4. Strain | Strain through a fine mesh, then a paper filter for clarity |
| 5. Dilute | Dilute concentrate with water, milk, or ice to taste before drinking |
Why Cold Brew Tastes Different
Cold water extracts a different balance of compounds than hot water — fewer acids and oils, more smooth, naturally sweet character — which is why cold brew tastes noticeably less acidic and bitter than hot-brewed coffee, even from the same beans.
Storage
Cold brew concentrate keeps well refrigerated for up to two weeks in a sealed container, making it convenient to batch-brew for the week ahead.
Cold brew is forgiving on ratio but unforgiving on grind size — always use a coarse grind. Anything finer will produce excessive sediment and a muddy, gritty cup.

Frequently Asked Questions
How long should cold brew steep?
12-24 hours is standard, with longer steeps producing a stronger, more concentrated brew.
Does cold brew have more caffeine than hot coffee?
The concentrate is stronger, but once diluted to a normal serving strength, caffeine content is comparable to hot-brewed coffee.
Can I make cold brew with any roast level?
Yes, though medium roasts are a popular middle ground — cold brew naturally smooths out roast-driven bitterness regardless of roast level.
Why is my cold brew gritty?
Your grind is likely too fine, or you skipped the final paper-filter straining step.
How long does cold brew concentrate last?
Up to two weeks refrigerated in a sealed container.
Patience Pays Off
Cold brew takes planning instead of precision — once you've got the ratio and steep time dialed in, it's one of the easiest ways to keep smooth, low-acid coffee on hand all week.
