Some things about Coffee extraction Summary of incomplete extraction of roasted coffee beans
The first coffee will not melt completely when thrown into the water. The maximum extraction rate of roasted coffee beans is 30% (substances that can be dissolved in water divided by the total weight of coffee). This seems to be nonsense: 1. Whether it's French pressure, Philharmonic pressure, all kinds of pressure, or espresso. The range of the best extraction rate is 18% Mui 21%. Insufficient extraction (less than 18%) indicates that the flavor of coffee is not fully soluble.

Coffee teaching class: explaining the main points of the theoretical knowledge of the golden cup rule of coffee.
Today we are going to discuss the "Gold Cup theory" of coffee. Some people do not like the gold cup theory, because the name seems to imply that as long as it meets this standard, it is "delicious coffee". In fact, I quite agree that coffee that is not in line with the golden cup theory is good, but it is a bit strange to say that we can ignore the golden cup theory at all. It may also be called "extract".

At this point, you need to increase the amount of powder (to get more concentrated dose) to enhance the concentrated flavor of the milk coffee. On the contrary, pure black coffee or small-dose milk coffee need to reduce the amount of powder. Milk coffee in many boutique cafes, strong

Global coffee demand grows at an average annual rate of 2.5% before 2020
The National Coffee Organization (OIC) predicts that global coffee demand is expected to grow at an average annual rate of 2.5% in the next six years, driven by strong demand from China, Russia and other countries. Demand will reach 175 million bags (60 kg each) in 2020, compared with 149.45 million bags in 2014. The agency said that this year's global production shortfall is 800000 bags, but for this situation.

The relationship between roasting degree and extraction rate when brewing coffee
The relationship between roasting degree and extraction rate when brewing coffee: the shallower the roasted coffee bean is, the harder the fiber is, and the harder it is to dissolve the flavor, so it is necessary to brew it with higher water temperature, longer time or finer grinding degree, so as to avoid insufficient extraction. On the contrary, deep-baked beans should be brewed in a lower water temperature, brewed in a shorter time or coarsely grinded, so as to avoid excessive extraction. Understand and put what you have learned into practice.

The correct Grinding method of Coffee Bean
The degree of grinding should be proportional to the extraction time. The roughness of coffee grinding will directly affect the extraction time and extraction rate. The finer the coffee is ground, the denser the powder layer is, the more coffee powder particles are in contact with hot water, the greater the extraction resistance, the easier it is to prolong the extraction time and improve the extraction rate, and it is easy to over-extract. On the contrary, the thicker the coffee is ground, the larger the gap in the powder layer is, and there are fewer.
