In the extremely hot weather, iced coffee has become the first choice of many people, and there are many ways to make iced coffee, such as iced coffee, iced coffee, iced American coffee, iced latte, etc., but what if you want to drink delicious and rich iced coffee at home? Today I will teach you how to make cold and cold coffee at home.

What is cold coffee?

Cold extract coffee is also a kind of coffee extracted with ice water. Like ice drop coffee, it takes a long time to make. But unlike ice drop coffee, ice drop coffee uses ice water to extract coffee flavor, while cold extract coffee uses ice water immersion to extract coffee flavor.

As it is not easy to extract macromolecular (bitter, mellow) flavor substances by soaking at low temperature, if medium and deep roasted coffee beans are used to make cold extracted coffee, the final product may lack a mellow taste. Therefore, for beans soaked in cold-extracted coffee, Qianjie coffee is recommended to use beans with outstanding flavor, or medium-to-medium roasted beans with sweet and sour feeling to make cold-extracted coffee.

For example, Qianjie Coffee's "Ethiopian Sidamo Fakui Coffee beans", medium and shallow roasting retains the unique and rich mixed berry acidity of the coffee. After being made into cold extract coffee, it will show the full sour and sweet compound berry juice, the fermented aroma of soft fruit wine and the taste of black tea.

In the "Honduran sherry beans" of Qianjie Coffee, for example, the barrel fermentation treatment with moderate roasting retains the aroma of the coffee and stimulates more caramel aromas. When made into cold extract coffee, it shows the aroma of sherry, the sweetness of vanilla cream and smooth taste, as well as the finish of nut chocolate.

Low temperature extraction for a long time can not only fully release the sweet and sour of coffee beans, but also control the release of bitter substances. compared with high temperature hand brewed coffee, cold extracted coffee will be fuller and cleaner.

How to simply make good cold coffee at home?

The production of cold-extracted coffee is very simple, and the tools for making cold-extracted coffee do not need to be too complicated. Only clean, sealed containers can be made.

The degree of grinding of cold-extracted coffee can be the same as that of hand-brewed coffee (the size of fine granulated sugar). Those who do not have a bean grinder at home can go to the coffee shop and ask the boss to grind them for you, or let the coffee beans be ground for you. At present, the coffee beans sold in Qianjie Coffee are issued 5 days after baking is completed, the default raw beans, packaging 100% fresh roasting. Partners in need can also note "cold extraction grinding powder" after placing an order.

In the production of cold extraction coffee will choose 40 grams of coffee powder, put 520ml of drinking water / ice water, the ratio of powder to water is 1:13. Then stir evenly, let the coffee powder in full contact with water, seal the bottle and put it into the cold layer of the refrigerator, then extract it at a low temperature for 8 to 12 hours.

As soon as the time is up, you can take out the coffee filter cup and put it on a filter paper / filter with high pore density to filter out the coffee liquid, and the cold extraction coffee will be finished. The utility model has the advantages of simple production, low technical requirements and high fault tolerance rate, so it is very easy to make good iced coffee.

Can cold-extracted coffee be extracted at room temperature? How long can you keep it?

Cold-extracted coffee is not recommended to be extracted at room temperature, and cold-extracted coffee is recommended to be extracted in the refrigerator freezer. The coffee liquid extracted and filtered can be refrigerated in the refrigerator for 72 hours.
