Cold Brew Coffee


Cold brew coffee is a coffee based beverage. Until recently, this beverage had been forgotten. It became common again in America and cafés across the world began to include it in their menus. You might have seen brown bottles in coffee shop refrigerators. The liquid inside is full of caffeinated coffee essence which is used to prepare cold coffee beverages.

Cold brew coffee has an old reputation and has been used for hundreds of years. One of the countries where cold brew has been around for centuries is Japan. The Japanese had a tradition of steeping powdered tea in cold water. Perhaps they tried this brown and finely ground power in cold water and were amazed by the thickness of the resulting liquid. This liquid was so thick and full of caffeine, that they named it coffee syrup. A small amount of this syrup could be mixed with large amount of water.

How to Make Cold Brew Coffee

In the cold brew method, coffee beans are not heated and they are not chemically processed. Consequently, their flavor and aroma is different relative to other coffee brewing methods. There are many devices to make a cold brew coffee such as: Mason jar, Toddy, French Press, Hario, Kyoto, and… However, here, we would like to explore one of the simpler methods of cold brew coffee:

First, you must grind the coffee beans to a large, coarse degree. Then, add the coffee grounds with a ratio of 1:8 with water to the Mason jar. Add coffee to the jar then cold water. Any container with a lid can be used in this method. Then, you completely stir the mixture of coffee and water. The container is then placed in the refrigerator for some time. The longer the container stays in the refrigerator, it will facilitate the extraction of the coffee essence. The amount of time coffee should remain in the refrigerator is between 14-24 hours.

Pour the contents of the container through a sieve in order to separate the coffee grounds from the coffee. Repeat this process twice in order to catch and separate as much of the coffee grounds as possible. The second time pour the coffee through a paper coffee filter. Repeat this process if necessary. If you filter the coffee several times and you still have coffee grounds in your coffee it is an indication that your coffee grind was smaller than necessary. Now, you can add flavors and other ingredients to the cold brew. Cover the container with a lit or fabric and in the refrigerator balance the flavor.
