The quality of coffee is judged by the sense of taste, which is called coffee cup test. The person who evaluates it is called a coffee quality appraiser. Similar to wine tasting, when testing a cup, make the coffee flow back and forth in your mouth and make full use of your sense of taste and smell to feel the coffee.

2015-12-16 Italian style coffee brewing way attention main points details introduction EspresWhen hot water is injected, the speed of filtration will be different, so the extraction time will also change. The difference in extraction time will lead to a difference in coffee flavor. The filtration speed varies with the area of the hole on the filter cup. The smaller the area is, the slower the filtration speed is. This type of filter cup will stay in the filter cup first because the injected hot water will first stay in the filter cup, and then filter at a certain speed, and the extraction will stop.

The main components of the thermal reaction are monosaccharides and sucrose, chlorogenic acid, free amino acids, and fenugreek amide. Both aravinose and calactose in the polysaccharides are transferred, and the basic vulcanization contains hydroxylated amino acid.

In 2011, the annual growth rate of China's coffee market reached the highest level of 19.6% in nearly a decade since 2005. Since then, the annual growth rate of China's coffee market has gradually decreased. The annual growth rate has gradually declined since 2011.

2014-10-09 Coffee knowledge coffee technology coffee roasting baking chemical reactionBefore we discuss the gouache ratio of coffee, let's briefly understand the following two concepts. It has also been mentioned earlier that the formation of coffee is that water brings out the soluble substance in the coffee powder, so it becomes coffee, and changing the amount of soluble matter can adjust the taste of coffee. I. the extraction rate of coffee refers to the soluble substance dissolved in the quantitative coffee powder.

The flow of milk is a little smaller, slowly increase the amount of milk. Slowly increase the flow, when there is a white spot, shake slightly left and right, remember that the flow rate of milk does not become smaller, in order to maintain a certain momentum. When the leaf shape appears, pull back slowly, the range of shaking becomes smaller slowly, and the flow rate of milk is also appropriate.
