International coffee tasters tell you the precautions for freshly ground coffee

How to make freshly ground coffee is the best? Can I have milk in my coffee? At the site of the establishment of the Chongqing Coffee Alliance held this afternoon, Zhang Ming, the first person in Chongqing to be qualified as a Q-Grade international coffee tasting expert and cup tester, popularized the general knowledge of coffee to the audience.

With the increasing demand for coffee, more and more citizens begin to make their own freshly ground coffee. For the choice of coffee beans, Zhang Ming suggests that it is best to choose freshly baked coffee beans, Zhang said. This is because roasted coffee beans usually begin to give off their own flavor the next day, reaching a peak on the seventh day, and then the flavor will gradually disappear. If it takes more than half a month, the flavor will be almost gone.

Zhang Ming said that before blending, the coffee beans are moderately ground so that the coffee powder and fine granulated sugar are about the same size. Secondly, the control of water temperature largely determines how "fragrant" the coffee is. The best water temperature is 90 ℃, because if the temperature is higher, it will "burn" the coffee, such as amino acids, aromatic hydrocarbons and other substances, if lower than 82 ℃, it is difficult to fully extract the coffee. Finally, for the concentration, it varies from person to person, and can be flushed according to the weight ratio of coffee powder and water from 1:10 to 1:18.

In addition, most people like to add milk to their coffee, which, in Zhang Ming's view, is not an appropriate approach. Zhang Ming explained to the audience that mixing milk and coffee for a long time would cause damage to the liver because the mixture would produce an unstable and indigestible emulsion. Therefore, it is best to drink black coffee, if it is too bitter, you can add honey or weakly alkaline probiotic sugar. In addition, many people think that it is easy to get angry if they drink too much coffee, which is actually a misunderstanding. Zhang Ming said that black coffee can protect the liver and stomach, and is very beneficial to diuresis and can speed up the circulation in the body. Therefore, instead of getting angry, drinking coffee can reduce the fire.

It is understood that at present, Chongqing Coffee Alliance has more than 50 members. Jia Ming, the founder of the alliance, said that the Coffee Alliance holds thematic activities, including tasting, in the cafes of its members every month, hoping to bring more people a good time through coffee.
