The method of brewing coffee introduces the design principle of coffee straw.

Degree of grinding

To do the correct grinding according to the coffee machine used, grinding can be roughly divided into three stages: rough grinding, medium grinding, and fine grinding.

Coarse ground coffee is suitable for filter coffee pot (traditional American brewer), medium ground coffee is suitable for follicular, flannel filter and siphon 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 water of good quality 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. Coffee beans

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