Coffee grinding tips

Grind before cooking, leave the coffee mellow

In addition to falling in love with the pleasant atmosphere that wantonly occupies the house, the most important thing is that they understand that grinding at the last minute before brewing is the basic secret of coffee preservation. Because grinding too early or buying ready-made ground coffee powder will increase the surface area of coffee in contact with air and humidity and gradually lose its aroma. In addition, due to different brewing methods, the suitable size of coffee powder particles is also different, so it is best to adjust the grinding degree according to the way of each brewing in order to make the coffee taste most incisively and vividly.

Rough, medium and fine grinding, each performing his own duties

Time, in the coffee bean life travel, always occupies an important position. The length of maturity determines whether the coffee is mellow or not. The long time for baking determines the degree of baking. If we say that brewing is a scene in which coffee beans are on and off when they meet with water. So, in this final critical plot, it is still time that matters. The length of brewing time not only determines the coffee concentration of different depth, but also affects the thickness of the grinding particles. Generally speaking, the shorter the cooking time, the more the coffee powder must try its best to expand its surface area and come into contact with water, and the finer the particles will be; on the contrary, the longer the cooking time, the rougher the grinding particles must be, so as to prevent unnecessary impurities from being extracted. For example, fast-extracted Espresso requires flour-like fine grinding, while filter brewing, which must be fully soaked to release the aroma, requires crumb-like rough grinding.

Offer a reward for excellent grinding equipment and book coffee

Grinding particle thickness, in addition to the particle size, uniformity is also a big point. If the size is different during grinding, the concentration of coffee brewed will be uneven. Fine grinding is usually backed by excellent grinding equipment. At present, most of the general household use are hand-operated grinders, while coffeeshop uses electric grinders that can quantify aroma and alcohol. Unfortunately, the hand grinder, which can give you the most elegant posture when grinding, although the shape is pleasing, it is often difficult to achieve the goal of uniform particles, so you must be very careful when buying, and it is best to try it before making a decision. Once you buy it home, you should rotate as gently as possible to avoid friction and heat and make the beans lose their fragrance. Grind to warm up for booking a good cup of coffee. So in every private conversation you have with coffee, don't miss the prologue of "grinding".

The matching equation of the size of VS particles in the way of cooking

* rough grinding: the size is as big as coarse sugar, suitable for filter coffee.

* medium grinding: gravel-shaped, the size is between coarse sugar and granulated sugar, suitable for trickling (filter paper dripping) cooking.

* Fine grinding: size as fine granulated sugar, suitable for distilled coffee pot, electric coffee pot, mocha pot.

* very fine grinding: the size is between salt and flour, suitable for Espresso, Turkish coffee, because household grinders can not grind this texture, generally must buy ready-made grinding powder, so if you want to enjoy Espresso at home, it is best to drink a large amount of fresh coffee.
