In summer, cold-extracted coffee has become the most direct communication topic for coffee lovers, and everyone is sharing their experiences in making cold-extracted coffee. Why has cold-extracted coffee become so popular in coffee circles these years? What's the difference between cold coffee and regular iced coffee? In front of this article, let's talk about this fascinating cold coffee. What is cold brewed / cold extracted coffee?

Cold-extracted coffee is a pure black coffee liquid made by direct contact between normal temperature / ice water and coffee powder at room temperature / low temperature. Due to the low temperature extraction, the flavor release of coffee powder is much slower than that at high temperature, so the total extraction time often takes 8-24 hours with the difference of room temperature / refrigerator temperature. The iced coffee with obvious aroma and high mellow thickness can be made without any skill and tedious brewing equipment. Soak in the evening and drink in the morning, which has become a good heart for many workers.

What is the difference between cold-extracted coffee soaked at room temperature and soaked at low temperature?

Cold extracted coffee at warm temperature is recommended to soak for no more than 8 hours, while cold extracted coffee at low temperature is recommended to soak for 12-24 hours.

The extraction time of cold-extracted coffee at room temperature will be different according to the room temperature. The coffee soaked at room temperature can show a mellow feeling immediately after extraction, but the disadvantage is that it is easy to soak out the woody flavor. The advantage of putting the refrigerator is that it can soak out a mellow feeling, at the same time, the wood taste is not easy to appear, the disadvantage is that the time is really long.!

What kind of coffee beans are suitable for cold extract coffee?

The liquid of cold extracted coffee is not as transparent as ice drop coffee, and a thin layer of oil will float on the surface, which will appear slightly thick and balanced in flavor and taste. Qianjie recommends using sweet and sour coffee beans / rich aroma beans to make cold extract coffee, such as Honduras Shirley coffee beans of front street coffee, Costa Rican Mozart coffee beans, Yega Xuefei sun red cherry coffee beans, Kenya coffee beans and so on are cost-effective coffee beans suitable for cold extraction.

The correct way of making Cold Coffee

Qianjie recommends making cold-extracted coffee in a refrigerator at a low temperature, especially in the south, where the room temperature is very high in summer. If you soak cold-extracted coffee at room temperature, it is difficult to control the soaking time properly.

Cold extraction coffee production parameters: 1:10 powder-water ratio, grinding degree for the Chinese standard No. 20 sieve (0.85mm hole) screening rate of 75%, soaked in ice water. When making cold extraction coffee, use 50 grams of coffee powder in front of the street, put 400 milliliters of filtered water and 100 grams of ice, stir well, and then seal the bottle and put it into the freezer. After low temperature extraction for 12 to 24 hours, the coffee grounds can be filtered out with a filtering apparatus after soaking and extraction.

The correct drinking method of Cold extracted Coffee

Qianjie recommends putting the extracted cold coffee in the refrigerator for 1 to 3 days before drinking, because the coffee liquid is fully melted and tastes better with the passage of time during the 36-hour overnight storage of 24 murmurs.

How long will the cold coffee last?

After being filtered, the cold coffee can be sealed in the refrigerator for 5 days. Although it is said that the longer the cold coffee is kept, the more mellow the flavor will be, but after all, the refrigerator environment is "complex" (especially in household refrigerators), so it is difficult to avoid the invasion of bacteria. So it is really not recommended to put it for a week or even a month before drinking.
