On the water and temperature of brewing coffee

As for the water and water temperature of coffee brewing, because northern China belongs to alkaline water quality, the water alkali is relatively large, ordinary water purifiers and water softeners do not have obvious effects, and the price is high, so Uncle Bean recommends that everyone use purified water. The water temperature is about 92 degrees. After boiling water in summer, open the lid and turn off the fire. If conditions permit, stir a few times with a long spoon. A minute later, it's about this temperature. The water is hot and the coffee is burnt.

Here is a description of a relationship, I hope to be able to explain clearly. Minas Serrado, also moderately roasted, is made with pressure, finely ground, more powder, high water temperature, long soaking time, high coffee concentration and heavy taste. On the contrary, it tastes light. I suggest that you do not use these elements at the same time, then coffee must be strong enough!

So say 9-12 grams of coarse granulated coffee powder, 150-180 ml of water. Soak for 3-4 minutes at a temperature of about 92 ° C, then slowly press down the filter plug. The coffee is more standard.
