The production of cold-extracted coffee can be said to be the easiest of so many coffee extraction methods, and does not require any technical knowledge. It is a way that a coffee rookie can easily make super-good iced coffee.

The taste of cold coffee

Cold-extracted coffee tastes good because soaking in low-temperature water does not easily release unpalatable substances (such as bitterness, astringency, etc.), but at the same time it can fully extract good substances (such as sweet and sour flavor). Therefore, cold-extracted coffee is cleaner and fuller than other high-temperature brewed coffee.

If you insist on the disadvantages of cold-extracted coffee, it may just take a long time to make, usually soaking in the refrigerator for 8-12 hours. However, Qianjie Coffee thinks that good coffee is worth waiting for ~ everyone can soak it before going to bed at night, and then get up the next day to drink a cup of refreshing cold coffee!

Do you need to buy a cold extraction coffee maker / cup?

With the popularity of cold coffee, there are many coffee machines / cups on the market. If you don't want to buy extra filtering equipment, you are recommended to choose a cold extraction coffee cup.

But it's okay if you don't have to buy it. Qianjie Coffee makes cold-extracted coffee in a clean, oil-free, sealed container. After the extraction is completed, the coffee grounds can be separated by using a high-density filter net / coffee cup + filter paper.

What coffee beans do you recommend for cold coffee?

It is not easy to extract bitter substances from cold-extracted coffee, so it is not recommended to use deep-roasted coffee beans. Cold extraction coffee before the production of street coffee recommends the use of coffee bean flavor is more prominent, sour and sweet more obvious medium-light-medium roasted coffee beans.

For example, Qianjie Coffee currently sells "Ethiopian Sun Cherry Coffee beans", with full sweet and sour berries, soft fruit fermentation and black tea-like sweet; or "Panama Flower Butterfly Coffee beans", with bright citrus acidity, fresh white flowers, sweet honey and green tea-like sweet. Or "Honduran Shirley Coffee beans" with whisky as sweet as vanilla cream and a nutty caramel finish.

The proportion and step explanation of making gouache powder with cold extraction

The proportion of cold extracted coffee is 1:13. For example, 30g coffee powder, we need to soak in 390g cold water.

In terms of grinding degree, Qianjie Coffee recommends that you use coffee powder with fine granulated sugar (the screening rate of China No. 20 standard screen is 75%). If you do not have a grinder at home, you can note the cold extract coffee powder when placing an order. Of course, the aroma of ground coffee will speed up, so if conditions permit, it is recommended that you grind it.

To make cold coffee, choose a clean container that can be sealed, then pour the coffee powder and the right amount of water into it, stir so that the coffee powder is in full contact with the water, then seal and refrigerate for 8-12 hours.

After the extraction time is about the same, you can take it out and filter it with a filtering tool, then pour it back into a clean and sealed container and store it in the refrigerator. After filtering the coffee grounds, the cold extracted coffee can be preserved for about 5 days. Please remember to drink it as soon as possible.
