How to Make Cold Brew Coffee at Home

Cold brew coffee is smooth, low in acid, and simple to make at home. You steep coarse grounds in cold water for hours, then strain. The result is a mellow concentrate you dilute to taste. No hot water and no special gear required.

This guide covers what cold brew is and how to make a batch. The guide also shows how cold brew differs from iced coffee. A big batch lasts most of the week.

What Is Cold Brew Coffee?

Cold brew coffee steeps ground beans in cold water for 12 to 24 hours. No heat means low acidity and a naturally sweet, smooth cup. The long soak pulls flavor slowly and gently.

Cold brew comes out as a strong concentrate, not a ready drink. Dilute one part concentrate with one part water or milk. Serve over ice for the classic version.

How to Make Cold Brew

Making this smooth iced brew at home takes five minutes of hands-on work. Use a coarse grind and a 1:8 ratio of coffee to water. Read our take on grinding your own coffee for the right coarseness.

Combine the grounds and water in a jar and stir to wet everything. Steep in the fridge for 12 to 24 hours, then strain through a filter or cloth. Longer steeps taste stronger, so adjust to your liking.

Cold Brew vs Iced Coffee

Cold brew and iced coffee are not the same drink. The cold-brew method steeps in cold water for hours, staying smooth and low in acid. Iced coffee brews hot, then chills over ice, keeping a brighter edge.

Each has a place, so try both and pick a favorite. See how to make iced coffee at home for the hot-brewed route. Prefer something quick? Read instant coffee vs cold brew.

How to Serve Cold Brew

Serve cold brew over plenty of ice, diluted to taste. Add milk, cream, or a splash of simple syrup for a sweeter cup. Keep the base unsweetened so you control every glass.

Store the concentrate in the fridge and use the batch within a week. Cold brew keeps best sealed and chilled, per FDA food-safety guidance. Fresh beans make the batch taste brightest.

Cold Brew Coffee Tips

A few habits make every batch better.

Grind Coarse

Grind coarse. Cold brew needs a coarse grind. Fine grounds turn the batch muddy and bitter.

Use a 1:8 Ratio

Use a 1:8 ratio. Start with one part coffee to eight parts water. Adjust stronger or weaker next time.

Steep 12 to 24 Hours

Steep 12 to 24 hours. Longer steeps taste bolder. Find your window and repeat.

Strain Twice

Strain twice. Filter once, then again if needed. Clean concentrate tastes smoother.

Store Cold

Store cold. Refrigerate the concentrate and use within a week. Cold storage keeps the batch fresh.
