Reason: ice drop coffee was originally invented to prolong the shelf life of coffee and extract it with ice water. Ice drop coffee refers to the use of ice water at or below normal temperature for a long time, usually 6-8 hours, to filter the coffee.
Many people ask the editor what kind of beans should be used to make ice drops.
As we all know, it is better to choose single bean to make ice drop coffee, which can effectively remove bitterness and tannin, taste rich and smooth, not sour, and does not hurt the stomach. sometimes we also use more than two kinds of single bean to make ice drops. Ice-drop coffee is more fragrant and tastes more delicate and subtle than cold-extracted coffee. First of all, you have to have a curling kettle, which you can buy at a treasure, HARIO and TIAMO. The household price is around 200.
[cold coffee]
Cold brewed coffee is a perfect combination of stronger coffee flavor and less bitter taste after 12 hours of soaking overnight compared with ordinary hot coffee. This coffee, which sounds like a lot of work, is actually much easier to make than expected. Simply put, soak the coffee powder in cold water, soak it overnight in the refrigerator, and then filter it.
In fact, the principle is similar to that of ice-drop coffee. Cold-extracted coffee is extracted with cold water for a long time, dissolving only small molecules such as sour fruit, flowers, etc., which tastes strong and smooth, showing the best original taste of coffee.

02 | hand-made iced coffee
We know that the lower the temperature is, the slower the extraction rate of coffee is, and it takes longer to achieve the ideal extraction rate, but if the time is too long, the bad ingredients of coffee are easier to extract. Usually we use ice water. This relatively extreme but stable way to get a cup of iced coffee for a long time, what should we do if we want to extract an ideal cup of coffee with ice water in a short time?
Prolong steaming time and water quantity
With the help of manual mixing
The grinding is relatively fine.
Lengthen the extraction time as long as possible

04 | end
For novice rookies, make iced coffee by hand, recommend test method 1: simple, rough and easy to use.
Although the result of hand-made iced coffee in this experiment is better than that of hand-made iced coffee, it does not mean that hand-made iced coffee is not feasible, it still has a certain flavor performance, compared with cold coffee, it may need to be ground more finely than ordinary hand-made coffee, or the temperature of steaming water is higher, the only thing that cannot be saved is the coffee extracted with ice water. You still need to refrigerate it in the refrigerator or add two ice cubes before drinking, so as to save the lives of your friends in the hot summer.
