Cold extract coffee, English name is Cold Brew Coffee. It is a kind of coffee beans ground into medium and fine particles and then treated with cold water. Generally soak in ice water for at least 8-12 hours, and then filter the coffee grounds to get the coffee liquid. If you want to have a higher thickness of cold-extracted caffeine, you can also extend the extraction time to 13Mel for 24 hours.

Is cold coffee the same as iced coffee?

Many friends confuse cold coffee with iced coffee when they first come into contact with each other. The reason is that we understand that iced coffee is the traditional idea of using hot water extraction and then adding ice cubes or ice to change the coffee from a hot temperature to an iced coffee.

The biggest difference of cold-extracted coffee is the coffee liquid extracted at low temperature. From the beginning of the article, we can see that the process of low temperature extraction of coffee belongs to cold extraction. "low temperature" and "long extraction time" are the two main characteristics of cold extraction coffee.

Taste characteristics of Cold extracted Coffee

The process of low-temperature extraction can greatly reduce the acidity and bitterness, making the flavor more sweet and mellow, and the taste of the coffee will be fuller and cleaner. In addition to being able to taste directly after extraction, its clean feature is also often used in coffee shops to make special coffee drinks.

Flavor characteristics of Cold extracted Coffee

The flavor of cold-extracted coffee depends on the beans used in making cold-extracted coffee. A good coffee bean can show the unique coffee taste of a region / producing area. And if you want to drink these unique flavors, fresh baking and fresh grinding are very important!

At present, the coffee beans sold in Qianjie Coffee are issued within 5 days after baking, and the original beans are sent by default. Although there is a grinding service, the coffee will taste better only if it is freshly ground and extracted.

Using coffee beans from Africa, cold-extracted coffee usually shows fruit-like sweetness, honey-like sweetness and tea-like sweetness. For example, Qianjie Coffee sells "Sakui Sun Coffee beans in Sidamo production area of Ethiopia", "Fruit Tintin Cooperative Water washing Coffee beans in Yegashifi production area of Ethiopia" and "Asalia Water washing Coffee beans in Sika production area of Kenya". It is more suitable for friends who like to have a strong sour taste.

Using coffee beans from Central and South America, cold coffee usually shows soft acidity, nutty almonds and caramel sweetness. For example, Qianjie Coffee sells "Panamanian Flower Butterfly washed Coffee beans", "Costa Rican Tara Pearl Coffee beans" and "Guatemalan Flower God washed Coffee beans". Others will ferment like ripe fruit depending on the treatment, such as "Costa Rican Mozart coffee beans".

The flavor of coffee beans in Asia is usually low acidity and mellow, and some mellow substances (such as bitterness) are not easily released at low temperature extraction, so cold extracted coffee made from Asian coffee beans may not taste as good as high temperature extraction.

The way of making cold-extracted coffee

Grind the coffee beans to medium fineness / sugar thickness, then put them in a sealed, clean container and add water according to your favorite powder-to-water ratio. For something rich, soak at 1:10, and for a balanced one, soak at 1:13.

Stir the coffee powder after adding the water, let all the particles come into contact with the water, seal and put in the refrigerator for 10-12 hours. After it is done, the cold extracted coffee liquid can be filtered out with filter paper, put it into a clean, sealed container and drink it within 72 hours.
