The most important thing to do when making the concentrate is to use the right ratio of ground coffee to water.

Cold Brew Concentrate vs Cold Brew Coffee

Essentially, regular cold brew is very similar to the concentrate. The only difference is that the concentrate is more potent and stronger than regular cold brew.

The two are made using a similar process that involves steeping coarse ground coffee in cold water for several hours and straining the mixture to get a ready brew.

The process is typically slower than that of making hot coffee. As a result, you’ll get a stronger and more flavorful brew due to the longer brewing time.

When making cold brew, you’ll use more coffee and less water than brewing hot coffee. Brewing with hot water removes some caffeine and flavors from the grounds.

Thus, cold brew is stronger than a regular hot brew. On the other hand, making the concentrate requires using more coffee and less water than cold brew coffee.

Thus, the concentrate is more potent than cold brew coffee. Also, the concentrate is more flavorful. Besides, it contains a higher caffeine content. That’s why you need to dilute it with water when serving.


Best Ratio for Making Cold Brew Concentrate

If you want to make a mid-level concentrate, especially if it’s your first time trying it out, combine 1.5 ounces of coarse grounds with 8 ounces of water. That’s an equivalent of ½ cup of coarse grounds and 1 cup of water.

If you prefer a more potent concentrate, combine 2 ounces of coarse grounds (2/3 cup) with 8 ounces of water (1 cup).

Recipe for Making Cold Brew Coffee Concentrate At Home

Required ingredients:

  • Coarse coffee grounds (4.5 ounces or 1 1/2 cups)
  • Cold water (24 ounces or 3 cups)
  • Ice cubes



Step 1- First, add coarse ground coffee into a glass jar.

Step 2- Pour cold water over the grounds.

Step 3- Next, stir the mixture to wet all the grounds evenly.

Step 4- Cover the container. Allow the mixture to steep at room temperature overnight or for at least 12 hours.

Step 5- Sieve the mixture. To do this, place a clean cheesecloth or kitchen towel on a sieve, preferably a fine-mesh type. Place the sieve over an empty container.

Pour the brew over the sieve to separate it from the grounds. Doing so will leave you with a cold brew concentrate.

You can refrigerate the concentrate in an airtight container.

With this recipe, you can make 4 cups of cold brew coffee from the concentrate. Thus, a ¼ of the concentrate in this recipe can be mixed.



You can prepare cold brew concentrate with coffee beans of your choice. It’s recommended to use freshly ground coffee for the best results.

You can grind coffee beans at home to stand higher chances of brewing with fresh grounds.

If you must buy pre-ground coffee, ensure they’re properly packaged and only buy the amount you can consume within a week.

Preferably, use coarse grounds to make the concentrate. The good thing is that making the concentrate at home allows you to customize it.

Thus, you can adjust the required ingredients depending on the amount and the strength you want.
