How to Make Cold Brew Coffee

How to make homemade cold brew coffee

Cold brew is coffee made with ground coffee beans steeped in cold water that gives the beverage its distinctive rich velvety taste which makes it the perfect refreshment for those long summer days when regular coffees are too hot to handle.

What is cold brew coffee?

Cold brew coffee has become popular in the past 10 years or so but has been around for many centuries.

According to some sources, the first evidence of cold brew coffee comes from Japan during the 1600s. However, other records point that cold brew coffee may have originated from traveling Dutch traders who used it during their cruises as a way to preserve coffee and later introduced the method to Japan.

Cold brew coffee is prepared by steeping coffee grounds in room temperature or cold water for an extended period of time, resulting in a delicious beverage that is completely different from simply pouring hot coffee over ice. The lack of heat prevents many compounds in the coffee from fully dissolving, creating a smoother and naturally sweeter profile with lower acidity and little bitterness.

Compared to traditional iced coffee, cold brew typically has a richer body, enhanced smoothness, and more delicate chocolate, fruity, or floral notes depending on the beans used. Because it is brewed slowly without heat, the extraction process highlights sweetness while reducing harsh bitterness.

Cold brew coffee: step-by-step recipe

Making cold brew coffee at home requires only a few ingredients and very little equipment. The process is simple and relies on time rather than heat to extract flavor from the coffee grounds.

Ingredients

Coarse ground coffee beans (100 g / 10 tablespoons)
Cold filtered water (1 liter / 34 ounces)
Ice cubes
Milk or plant-based alternatives, optional
Sweetener of choice, optional

For the best results, use freshly ground medium or dark roast coffee beans with a coarse texture similar to breadcrumbs. A coarse grind helps avoid over-extraction and creates a cleaner, smoother final cup.

Filtered water is also highly recommended because water quality directly affects the aroma and overall taste of the coffee.

How to prepare Cold brew

Follow these simple steps to prepare homemade cold brew coffee:

Ground your coffee beans so that they have a texture similar to breadcrumbs using a De’Longhi grinder.
Add the ground coffee to a large jar, French press, or dedicated cold brew container.
Slowly pour the cold filtered water over the coffee grounds and stir gently to ensure all the coffee is evenly saturated.
Cover the container and let the coffee steep for about 12-24 hours at room temperature or in the refrigerator. The longer the steeping time, the stronger and more concentrated the flavor will become.
Filter the coffee through a fine mesh sieve, paper filter, or cheesecloth to remove the grounds and obtain a smooth concentrate.
Dilute the concentrated coffee essence with water, milk, or ice according to your preferred taste and serve chilled.
Enjoy the cold caffeine freshness.

Making cold brew at home becomes even easier with the right equipment. De’Longhi manual espresso machines, such as La Specialista series, allow you to prepare smooth and refreshing cold brew beverages in just a few minutes instead of waiting overnight, combining convenience, consistency, and café-style results for an effortless at-home coffee experience.

How to serve it

Cold brew coffee can be enjoyed in many different ways depending on your taste preferences:

Serve it over ice for a refreshing everyday drink, or add milk, oat milk, vanilla syrup, caramel, or sweet cream for a richer coffeehouse-style beverage.
For a more intense flavor, use coffee ice cubes made from frozen brewed coffee to avoid diluting the drink.
Cold brew also works perfectly as a base for flavored cold foams, summer coffee cocktails, or blended coffee drinks.

Variants and characteristics

One of the reasons cold brew coffee remains so popular is its adaptability. Once you master the basic recipe, you can experiment with different coffee origins, roast profiles, and flavor combinations to create personalized drinks at home.

Popular cold brew variations include:

Vanilla sweet cream cold brew
Salted caramel cold brew
Mocha cold brew with chocolate syrup
Coconut cold brew with plant-based milk
Nitro cold brew for an even creamier texture
Protein cold brew smoothies for breakfast

You can also experiment with lighter roasts for brighter fruity notes or darker roasts for deeper chocolate and nut flavors.

Frequently asked questions about cold brew coffee

Is cold brew coffee stronger than regular coffee?

Cold brew concentrate can contain more caffeine than regular brewed coffee depending on the coffee-to-water ratio and steeping time. However, it is usually diluted before serving, making the final caffeine content similar to other coffee beverages.

How long should cold brew steep?

Most cold brew recipes require between 12 and 24 hours of steeping time. Shorter steeping times create a lighter and milder flavor, while longer extractions produce stronger and more concentrated coffee.

How long does homemade cold brew last?

When stored in an airtight container in the refrigerator, homemade cold brew can maintain its flavor for up to one week.

What type of coffee beans are best for cold brew?

Medium and dark roast coffee beans are commonly preferred for cold brew because they create smooth chocolate, caramel, and nutty flavor notes. However, lighter roasts can also work well if you prefer brighter fruity or floral aromas.
