Qianjie-introduction to the knowledge and grindability of hand-made coffee

90% of the cafes on the market actually drink espresso, espresso extracted by coffee machines at high temperature and pressure, and fancy coffee such as latte, mocha and cappuccino, all made with espresso.

The gradual emergence of those "origin + treatment methods" (for example: Yejia Xuefei washing) after the emergence of individual coffee on the market, refreshing many people's stereotype of coffee-coffee can be non-bitter; like wine tasting, drink the aroma and fruit of different coffee beans; the most simple hand-brewing method, no milk and no sugar, is the best way to give full play to the true flavor of individual coffee.

When we taste it carefully and challenge our sense of taste, we will experience the natural flavor of coffee beans from Africa, South America and Pacific islands: the fruity flavor of Kenya AA, the full-bodied and bitter taste of Mantenin, the citrus acidity and floral aroma of Yejachefi, the balance and chocolate aroma of Costa Rica, and so on.

Hand-brewed coffee (Dripping Coffee) can be said to be the healthiest way to brew coffee, because almost all unhealthy substances such as coffee oil and caffeine (but also some aroma volatiles) are filtered under the action of filter paper, and the pure and elegant aroma of coffee makes you feel a natural serenity.

The hand brewing process of a single cup of coffee seems simple, but in fact, it is necessary to consider many factors, such as the grindability of coffee beans, the ratio of water to powder, the hardness of water, the soaking time, the water temperature, the selection and matching of hand flushing utensils, and so on. The change of any of these factors will cause the flavor of the final coffee, and it is precisely this ever-changing hand brewing technique that can make the individual coffee more show the personality characteristics of coffee beans. The freshness of coffee beans roasted and so on.

Different bean grinders have different grinding effects. (even if it is the same brand, the same model) different cutter types, different shapes of coffee powder particles, the extraction effect of coffee is also different. (some are flaky, some are blocky, some are round)

With different bean grinders, the size distribution of coffee powder particles is different, and the extraction effect of coffee is also different. (some have more fine powder ratio and some have less fine powder ratio)

Suggestion: to discuss the degree of grinding with others, it is best not to say what the scale is, but to describe the sense of granularity to the touch as much as possible. For example: like flour, like salt, like coarse salt, fine sugar, coarse sugar.

Knowledge: hand-brewed coffee is made by hand with a single variety of coffee beans from a single origin, and even people who pay attention to roasting and grinding beans themselves.
