Cold-extracted coffee is a method of extracting coffee. By soaking in cold water and low temperature for a long time, the sweet and sour substances in coffee beans can be released as much as possible, and at the same time, it can also prevent the release of unpleasant bitter and astringent taste, which can not only increase the alcohol thickness of coffee, but also maintain the overall cleanliness of coffee.

The reason why cold coffee is bitter / bad

Because coffee beans are seeds, the oil of the seeds will be richer than other parts of the plant, so no matter which variety of coffee beans, the deeper the roasting, the more the oil will show on the surface and taste of the beans.

According to the experience of Qianjie coffee production, the taste of shallow roasted coffee beans is usually lighter, partial to fruit juice, more sour, flower and fruit aroma up, and does not smell like the coffee in the impression; on the other hand, the taste of deep-roasted coffee beans is thicker, the aroma is heavier, and it smells closer to the "coffee flavor" in the impression.

If the cold extract coffee is bitter, it may be made from deep-roasted coffee beans with a high concentration. At this time, Qianjie coffee is recommended to add the right amount of cold water / ice to dilute.

If the shallow roasted coffee beans are used, it may be caused by soaking for too long. Generally, cold-extracted coffee is soaked for 8-12 hours. After soaking for too long, the coffee powder will release all the delicious flavor substances, and those bitter and astringent substances that do not agree to be released will also be released slowly. Therefore, after soaking for 12 hours, we must first filter the coffee grounds in the coffee and then seal them.

The correct way to make cold coffee

The characteristics of cold extraction caffeine can highlight the aroma of wine, fruit fermentation and fruit aroma in coffee. So the coffee beans used in cold extraction coffee, Qianjie Coffee recommends the use of medium-to medium-roasted coffee beans with rich fruit flavor, or coffee beans with outstanding aroma. For example, "Front Street Costa Rican Mozart coffee beans, with the aroma of dried grapes", "Front Street Ethiopian Rose Valley coffee beans, with rich mixed berry acidity", "Front Street Honduran sherry coffee beans, with the smell of whisky".

No matter which one you use with beans, the premise is to choose fresh baked ones. As the coffee after roasting after 4-7 days of bean cultivation period, will enter a best taste period, after this period of coffee aroma will accelerate volatilization, flavor taste will be greatly reduced. Qianjie in order to ensure that everyone drinks coffee flavor in the best period, will ship within 5 days of freshly roasted beans, so that everyone received the best aroma of coffee beans.

Qianjie Coffee tends to use medium-to-light roasted coffee beans when making cold coffee. All you need is a clean container that can be sealed. Prepare 40 grams of coffee powder, grind it into a fine grind (85% pass rate of sieve 20) into a container, then pour in 480 ml of cold water, stir with a stick and cover.

Put it in the refrigerator and refrigerate for about 12 hours. After filtering out the coffee grounds, the coffee liquid can be drunk immediately. You can also put the filtered coffee liquid into a bottle and refrigerate for 4 hours. The flavor and taste will be better.
