What is the ratio of cold extracted iced coffee powder to water? cold extracted cold brewed coffee making method recommended for cold extracted coffee beans

Many people will distinguish cold coffee from iced coffee because we understand that iced coffee is extracted with hot water and then iced or chilled to change the coffee from hot to iced coffee. The biggest difference of cold-extracted coffee is the cold water used throughout the process and the coffee liquid obtained by low-temperature extraction. Qianjie Coffee to share the knowledge of cold coffee!

What is cold coffee? Cold extracted coffee, known as Cold Brew Coffee in English, the ground coffee powder is directly soaked in cold water, usually takes more than 8 hours, and the chilled coffee liquid is filtered by utensils. When making cold-extracted coffee, we can adjust the flavor and concentration of coffee by changing the degree of grinding, soaking time and the ratio of powder to water.

Compared with hand-made and Italian high-temperature extraction, cold extraction weakens the release of bitter tannic acid, so the acidity and bitterness are not obvious, and the population is smooth taste and clean and clear flavor. The extraction temperature of cold extraction coffee is not as high as that of hot coffee, and it is not easy to extract miscellaneous and bitter taste, so the cold extraction method will faithfully reflect the treatment and roasting degree of coffee in the performance of flavor. Through cold extraction, the aromatic substances of coffee stay longer in cold water, and the low temperature shows a more natural aroma of flowers and fruits. Because the flavor of small molecules is easier to dissipate, although the cold-extracted coffee is stored in a low-temperature freezer, the flavor of small molecules such as flower fragrance becomes less obvious as it is stored for longer. Therefore, Qianjie suggests that the cold extract should be filtered and stored in an airtight container for no more than 5 days to avoid the loss of flavor and the growth of bacteria.

Preparation method of cold-extracted coffee

The method of making cold-extracted coffee is very simple. First of all, we need to prepare a bag of coffee beans during the appreciation period, an airtight container for coffee extract, and filter bags or paper and cups for filtering coffee grounds. The front street here is made of home-baked Honduran litchi orchid coffee beans, this coffee uses brandy barrel fermentation, with a strong aroma of fermented wine, sweetness is very obvious, reminiscent of honey and litchi, very suitable for making cold extract, ice drop coffee.

① weighed 40g litchi orchid coffee beans with an electronic scale and ground them into fine granulated sugar. The grinding degree of Qianjie will be adjusted by China 20 standard screen, and the pass rate of cold extraction is 75% 85%. The grinding scale is 9.5% 10.5.

② pours the ground coffee powder into a sealed bottle and Qianjie uses a powder-to-water ratio of 1:10, that is, 400g of room temperature water.

③ close the lid and shake it evenly. You can also use a blender to fully touch the powder and put it into the refrigerator for low temperature and slow extraction for 8 minutes for 12 hours.

When the ④ time is up, the coffee grounds are isolated and removed with filter paper (filter). The clear coffee liquid can be enjoyed immediately, or it can be refrigerated to wait for the flavor to be fermented and ripe, which will form a fuller fermented taste.

What coffee beans are recommended for cold extract coffee?

With regard to the choice of coffee beans, Qianjie believes that coffee beans with different processing methods or roasting degrees can be selected according to their preferences, as long as freshly roasted coffee beans are selected. 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.

The characteristics of cold extraction caffeine can highlight the aroma of wine, fruit fermentation and fruit aroma in the coffee. If you don't know which coffee beans to choose, you can refer to the coffee listed in front of the street.

After 3-4 days of low temperature storage and fermentation, the flavor of the wine is more obvious.

Why is there no cold coffee in the front street store? If you come to the shop of Qianjie Coffee, you will find that Qianjie only serves ice drop coffee, not cold coffee. The reason is that the front street repeatedly uses different beans to make ice drop coffee and cold extract coffee, the appearance of ice drop coffee will be more transparent and beautiful than cold extract coffee. And in the sense, ice drop coffee will also be cleaner and refreshing! Therefore, in both, Qianjie chose ice drop coffee. But cold coffee also has its advantages, such as the lower cost of utensils, the simple way of making it, and its unique taste.
