Fresh coffee beans make good coffee.

See: Look at shape and color. Good coffee beans are full and bright in shape, otherwise they are incomplete in shape, dark black coffee beans are bitter, and yellow ones are sour.

Grasp: Grasp a handful in the palm of your hand and feel whether it is a solid bean.

Nose smell: Put it on the tip of your nose and smell it. Fresh coffee beans smell strong, otherwise they smell bad or tasteless.

Hand pressure: Fresh beans are crispy when pressed, and there is fragrance floating out when cracked.

Bite: Put the beans in the mouth and bite twice. The crisp sound indicates that they are not wet and the coffee beans are well preserved.

Grinding: Fresh coffee beans are easy to adhere to the outlet of the grinder when grinding.

Brewing: Fresh coffee beans are rich in foam when brewed, and the foam will be layered with coffee grounds.

Note: enough fresh coffee beans can bring the unique flavor of coffee to the limit, giving people the ultimate enjoyment of lingering fragrance. Therefore, the freshness of coffee beans is the most important.
