Coffee technology how to make a cup of strong coffee

Choosing good coffee is the first step in making good coffee. The temperature of water and the contact time of coffee powder during correct storage, grinding, brewing and brewing are all important factors affecting coffee quality. How to make delicious and mellow coffee must be matched by a series of factors:

Coffee beans: want to brew a cup of mellow coffee, in addition to brewing skills, the most important thing is to buy good quality coffee beans. When buying, you should also pay attention to whether the color and particle size of the beans are uniform. Good coffee beans are not only shiny in appearance, but also have a strong aroma without being mixed with peculiar smell.

Degree of grinding: to do the correct grinding according to the coffee machine used, grinding can be divided into three stages: rough grinding (percolator), medium grinding (drip coffee), and fine grinding (espresso machine). While coarse ground coffee is suitable for filter coffee pot (traditional American brewer), medium ground coffee is suitable for follicle type, flannel filter type, siphon type coffee pot, and fine grinding is most suitable for coffee distiller (also known as water drop coffee maker). And I would like to remind you that the shorter the brewing time, the more detailed the grinding particles should be. Because the smaller the particles, the larger the area of contact with hot water, so the brewing time is shorter. And too fine grinding will make the coffee more bitter, but also easier to block the coffee machine; too rough grinding, it will make less flavor coffee.

Fresh and warm water: 97% of the coffee is water, and only good water can brew the original aroma and richness of the coffee. It is best to use filtered water to make coffee. Do not boil the coffee, because boiling water will make the coffee bitter, but also pay attention to the temperature of the water should be slightly lower than 96 degrees Celsius.

The coffee had better not be reheated. When cooking, you should pay attention to only the amount needed for each cooking, and it is best to drink it when it is just cooked. The best drinking temperature for coffee is 85 degrees Celsius.
