General knowledge of brewing coffee about the water and temperature of brewing coffee

With regard to the water and water temperature of 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 an obvious effect, and the price is not cheap, so uncle beans suggest 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.

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. I advise you not to 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.
