The planting of coffee beans the roasting of coffee beans

Proper grinding is related to the success or failure of a cup of coffee, no matter what brewing method has its correct extraction standard, which can also be called the decomposition mass of water molecules in coffee beans. The simple rule is that the shorter the brewing time is, the finer the grinding scale is. In addition, in the same operation mode, the amount of brewing weight, in order to achieve a balanced operation quality, it is also necessary to adjust the grinding scale properly.

Different grinding designs also lead to different grinding effects. According to the needs of its operation, the selection of appropriate grinding tooth disk (blade) and appropriate motor speed will greatly improve the taste of coffee. Choosing a suitable package or container and storing it in the right space is what it is all about, but fresh coffee is extremely sensitive to the preservation environment. In recent years, experts have strongly recommended the use of aluminum foil packaging material (opaque) with one-way exhaust valve, which has been praised and recognized by large domestic and foreign manufacturers, blocking the invasion of oxygen and being able to discharge carbon dioxide, greatly prolonging the honeymoon period of tasting fresh coffee. As for storage, I think it only needs to be placed in the shade where it is not susceptible to moisture and does not have direct sunlight. Refrigeration or freezing is not absolutely ideal. Excessive shrinkage of fiber, condensation of benign grease, peculiar smell in the refrigerator, and the difference in temperature during extraction are all thought-provoking, aren't they?

Brewing of coffee beans

The process of dissolving out the water-soluble components of ground coffee in any way can be called brewing or extraction, just like coffee beans, no kind of coffee is flawless, and the extraction of coffee is the same. no method is flawless.

In a cup of coffee, water accounts for more than 98%. Choosing the appropriate water quality is the first condition for brewing coffee, which contains moderate carbon dioxide and calcium. The purified water of magnesium is helpful to the extraction of good quality content to a certain extent, and the behavior of groundwater / tap water / mineral water / distilled water is arranged in order according to the taste of taste, but both groundwater and tap water are called ideal after secondary purification. As for mineral water and distilled water, some experts call it boring water, which has a certain negative effect on the balance of taste.
