Individual coffee favorite ice drop coffee in summer

Ice-drop coffee is a very unique and well-received coffee making method, allegedly invented by the Dutch, requiring the use of a special ice-drop coffee pot, if you have enough patience, you can get a cup of high purity, unique flavor of good coffee. Because the acidic fat in coffee is not dissolved efficiently in cold water, the sour taste in the taste of iced coffee will be significantly weakened. In addition, the caffeine content is low under low temperature extraction, and the low temperature can also effectively reduce the aroma volatilization, which is very helpful for preserving the coffee aroma. Iced coffee is also known as "stomach coffee."

I seldom suggest that students 'coffee shops provide iced coffee in Beijing on weekdays, not because iced coffee is not good, but because iced coffee relies far more on water quality than hot extracted coffee, and Beijing water quality is really unsatisfactory. If the water purification device is not strong, the effect can be imagined.

Steps:1. An ice drop coffee pot of general construction is divided into three basic units: an upper pot, a middle pot and a lower pot, wherein the upper pot holds an ice water mixture and the middle pot is a coffee powder cup. First, close the water control valve at the lower end of the upper pot and pour pure cold water or ice water mixture into the upper pot.

2. Place the clean lower pot under the middle pot to receive the extracted coffee.

3. Place a filter paper under the coffee powder cup, place the appropriate amount of ground coffee powder in it, gently pat it a few times to make the coffee powder level, and then lay a filter paper on it.

4. Open the water control valve at the bottom of the upper pot to adjust the speed of water dripping. Generally, we control the speed to 40~50 drops/minute, so it takes 5 to 8 hours to obtain 1000 ml of iced coffee. My habit of making iced coffee drops at home is to start at night before going to bed and finish right after waking up the next morning.

5. When the upper pot runs out of water, we can take the lower pot down and enjoy our coffee.

6. If you want iced coffee to present the best flavor, you can bottle the extracted iced coffee and store it in the refrigerator. On the third to seventh days, the coffee flavor is in the best state, just like wine, showing complex and elegant flavor. No wonder it has won the reputation of "iced coffee", and its longest drinking period can be close to half a month. (This article is from Coffee)
