Qianjie-introduction to the production of cold extract coffee

Cold brew cold extract coffee, to put it simply, is to soak the coffee powder in water in various forms, refrigerate and rest, and then filter the extract. It can be said to be twin with another kind of brother ice drop coffee (dutch coffee), but it is different. Ice droplets are coffee liquid gathered by slowly filtering the coffee powder with ice-melting ice water.

Because the tannin content of coffee extracted by ice water is greatly reduced, yes, it is the tannin in red wine. As we all know, the higher the content of tannin, the more astringent the taste. Cold extracted coffee tannins dissolve very little, but the aroma molecules in coffee can be retained, such as flower and fruit aroma.

After soaking for a long time, the coffee will also undergo a slight fermentation process, so the taste will be sweet and smooth. In addition, this type of coffee contains 20% less caffeine than regular coffee. People who are sensitive to caffeine can also drink cold extract or ice drops if they want to reduce the effect of coffee on you. Due to equipment and technical requirements, you need to order ice droplets in the cafe. But cold extract, everyone can do it at home.

Because there is no heat treatment, the smoky and roasted flavor of coffee is not easy to extract. Unlike hand flushing, water temperature, time, flow rate and grinding degree of powder are all variables, the control variables of cold extraction are few, and the taste is more stable. As long as the beans are of good quality, the novice is not easy to miss. In the case of refrigerated and sealed, cold-extracted coffee can be kept for three weeks and can be mixed with water, ice and milk. So many cafes will sell homemade bottles of cold extract, the sale is very attractive.

Cold brew is soaked coffee, as the name suggests, you need a container that can be soaked (as large as possible) and a tool that can be filtered.

The choice of coffee powder: coffee powder should be roughly grinded, thicker than hand punching, close to the coarseness of french press. Unsure friends can compare coarse granulated sugar, which is thicker than coarse granulated sugar. If you buy powder directly, you can buy coffee powder for French presses.

The ratio of gouache to flour: 1. It is recommended that it be thicker, mix it with water or make other flavors when drinking, and condense it and put it in the refrigerator to save space.

1. Grind the coffee into a kettle and pour it into drinking water (room temperature).

two。 Stir to make sure the coffee powder is soaked in water.

3. If the compartment of your refrigerator is high enough, you can close the lid, but don't press down the filter layer. If the refrigerator layer is not high enough, you can wrap it in plastic wrap and put it in the refrigerator.

4. Refrigerate for 12 hours, remove and press down the filter, enjoy directly, or refrigerate in a sealed container.

The filter net of the French kettle is relatively fine, and the coffee made is relatively clean.

Knowledge: the choice of cold extracted coffee beans is recommended. Coffee beans can be selected according to their favorite flavor.
