Water dance curry fragrance-- Water quality and water temperature of brewed coffee how to boil coffee with pure water

On the problem of water and water temperature for brewing coffee: because the water quality in northern China is alkaline, the water alkali is relatively large, ordinary water purifiers and softeners do not have obvious effect, and the price is not cheap, so it is recommended that we use pure water. The water temperature is about 92 degrees. After boiling the water in summer, open the lid and turn off the fire. If possible, stir several times with a long spoon. A minute later, it was about the same temperature. The water temperature is high and the coffee is scorched.

"this condition is too harsh. What should I do with the water cooler?" The hot water temperature of the water dispenser is less than 90 degrees. With the same fineness of powder and the same soaking time, the coffee will be light and the extraction will be insufficient. It should be solved by prolonging the soaking time. Therefore, if you use the water from the water dispenser and use legal pressure to make coffee, the soaking time of coffee should not be less than 5 minutes.

Here to describe a relationship, I hope I can make it clear. Minas-Serrado, which is also moderately roasted, is made by pressure, fine grinding, high powder quantity, high water temperature, long soaking time, high coffee concentration and thick taste. On the contrary, the taste is light. It is suggested that we should not use all these elements at the same time, then the coffee must be very strong!

So 9-12 grams of coffee powder as fine as coarse sugar, 150-180 milliliters of water. Use a water temperature of about 92 degrees, soak for 3-4 minutes, then slowly press down the filter plug. The coffee made is relatively standard.

But I want to tell you that the quality of coffee must be identified by tasting. Everyone likes to use data to make it, but the data is just a reference. The taste varies from person to person. Although people find it difficult to tell whether coffee is good or bad by tasting it, it is the straightest and shortest way.
