Cool summer taste the taste of ice drop coffee
Steps to use:
1. A common ice drop coffee pot is divided into three basic units: the upper pot, the middle pot and the lower pot, in which the ice water mixture is placed in the upper pot and the coffee powder cup is in the middle pot. First close the water control valve at the bottom of the upper pot and pour pure cold water or ice water mixture into the upper pot.
two。 Place the clean pot under the middle pot to receive the extracted coffee liquid.
3. Put a piece of filter paper on the flat pad under the coffee powder cup, place the right amount of ground coffee powder in it, gently pat to smooth the coffee powder, and then place a piece of filter paper flat on it.
4. Open the water control valve at the lower end of the upper pot to adjust the speed of water dripping. Generally speaking, if we limit the speed to 40-50 drops per minute, it will take 5 to 8 hours to get 1000 ml ice drops of coffee. My habit of making iced coffee at home is to start before going to bed at night and finish it when I get up the next morning.
5. When the water in the upper pot runs out, we can take down the next pot and enjoy the coffee.
6. If you want the ice drop coffee to show the best flavor, you can bottle the extracted ice drop coffee and store it in the refrigerator. The coffee flavor is in the best condition from 3 to 7 days, showing a complex and elegant flavor like wine brewing. No wonder it has won the reputation of "ice drop wine brewed coffee", and its longest drinking period can be close to half a month.
