How to choose good coffee beans

Sniff

Hold the coffee beans close to your nose and smell them deeply, whether you can clearly smell the aroma of the coffee beans, if so, it means that the coffee beans are fresh enough. On the other hand, if the aroma is faint or has begun to appear greasy (similar to the smell of peanuts or nuts that will appear after a long time), it means that the coffee beans are not fresh at all. No matter how much effort you put into grinding and brewing such coffee beans, it is impossible to make a good cup of coffee.

Hand pressed

Take a coffee bean and try to peel it by hand, if the coffee bean is fresh enough, it should be easy to peel off, and it will have a crunchy sound and feeling. If the beans aren't fresh, you'll find it seem like you'll have to struggle to open a bean. Another important thing to observe when peeling the coffee beans is to see if the heat is even during roasting.

If it is uniform, the color of the outer and inner layers of the beans should be the same. If the color of the outer layer is significantly darker than that of the inner layer, it means that the heat may be too strong during roasting, which will also affect the aroma and flavor of the coffee beans.

The transformation from bitter to sweet is the skill and condition of a good cup of coffee.

1. Smell the fragrance. The coffee should be able to feel its full-bodied aroma in both the bean and powder state, and the aroma will be further stimulated during the extraction process due to contact with hot water. However, it should be noted that the smell must be hot, as the temperature drop or iced coffee will make the aroma quite closed.

Natural floral and fruity aromas are naturally the best enjoyment, and if you smell the flavor of the coffee itself, then you should be wary, which may be a trick to cover up the poor quality of the coffee itself.

2. Taste. The bitterness of coffee is the most representative flavor and the most sensitive taste sensation of people. It's a substance in coffee called chlorogenic lactone, which increases with the degree of roasting of the coffee, which is why dark roasted coffee is especially bitter.

It's not that the bitterer is better or worse, on the one hand, it has to suit your taste, and on the other hand, the good bitterness can blend with the sourness and sweetness to form the perfect Daigo taste. The coarser bitterness is very straight, as if taking Chinese medicine.
