How do you make cold brew coffee?
To make cold brew coffee, combine coarsely ground coffee with cold water, let it steep for 12 to 24 hours, then strain the grounds. The result is a smooth, low-acid coffee concentrate that can be diluted with water or milk.
Cold brew coffee has become one of the most popular types of coffee to enjoy at home because of its rich flavor, low bitterness, and smooth flavor.
What Is Cold Brew Coffee?
Cold brew coffee is made by steeping coffee grounds in cold or room-temperature water for an extended period of time. Unlike hot brewing methods, it does not use heat, which results in a smoother, less acidic flavor profile.
Because of the slow extraction process, cold brew tends to highlight chocolatey and mellow notes while reducing sharp or bitter flavors.

Cold Brew Coffee Ratio
The coffee-to-water ratio is one of the most important parts of making cold brew.
A common ratio is about one cup of coarsely ground coffee to four cups of water when making a concentrate. This concentrate can later be diluted with equal parts water or milk before drinking.
If you prefer ready-to-drink cold brew, you can use a weaker ratio, such as one cup of coffee to eight cups of water.
Adjusting the ratio allows you to control the strength and flavor of the coffee.
Grind Size for Cold Brew
Grind size plays a major role in cold brew extraction.
A coarse grind is ideal because it prevents over-extraction and makes straining easier. If the grind is too fine, the coffee can become bitter and cloudy.
Using a burr grinder (a grinder that uses two revolving abrasive surfaces to grind coffee) helps achieve a consistent coarse grind, which improves the overall flavor of the final product.
Step-by-Step: How to Make Cold Brew Coffee
Start by adding coarsely ground coffee to a large jar or container. Pour cold or room-temperature water over the grounds and stir gently to ensure all the coffee is saturated.
Cover the container and let it steep at room temperature or in the refrigerator for 12 to 24 hours. A longer steep time will produce a stronger, more concentrated flavor.
After steeping, strain the mixture using a fine mesh sieve, cheesecloth, or coffee filter to remove the grounds. The remaining liquid is the cold brew concentrate.
Dilute the concentrate with water, milk, or a milk alternative to taste, then serve over ice.
How Long to Steep Cold Brew
Steeping time affects strength and flavor.
A shorter steep time of around 12 hours produces a lighter, smoother brew. A longer steep time of up to 24 hours results in a stronger, more intense concentrate.
Most people find that cold brew steeped for 16 to 18 hours provides the best balance of flavor and smoothness.
Why Cold Brew Tastes Less Acidic
Cold brew coffee is often described as less acidic than hot coffee.
This is because cold water extracts fewer acidic compounds from the coffee grounds. The result is a smoother taste that is easier on the stomach for some people.
However, cold brew still contains caffeine and natural coffee compounds, so it should still be consumed in moderation.
How to Store Cold Brew Coffee
Cold brew can be stored in the refrigerator for up to one week.
Keeping it in an airtight container helps preserve freshness and prevent it from absorbing odors from other foods.
Because it is often made as a concentrate, it can be diluted as needed throughout the week for quick and convenient coffee.
Tips for Better Cold Brew
Using freshly roasted coffee beans improves flavor and aroma. Filtered water also helps create a cleaner taste.
Experimenting with different beans can produce a range of flavors, from chocolatey and nutty to fruity and bright.
Straining the coffee thoroughly is important to avoid sediment and achieve a smooth finish.
Frequently Asked Questions
What is the best coffee for cold brew?
Medium to dark roast coffees are commonly used because they produce a smoother, richer flavor, though lighter roasts can add more brightness.
How much caffeine is in cold brew coffee?
Cold brew is often higher in caffeine when consumed as a concentrate, but the final amount depends on how much it is diluted.
Can you use regular ground coffee for cold brew?
You can, but a coarse grind is strongly recommended for best results and easier filtering.
Is cold brew stronger than regular coffee?
Cold brew concentrate is stronger, but when diluted, it is similar in strength to regular coffee.
Do you need special equipment to make cold brew?
No special equipment is required. A jar, water, coffee, and a way to strain are all you need.
