Teach you the trick of distinguishing the freshness of coffee beans

Smell: fresh coffee beans smell strong fragrance, otherwise tasteless or bad smell.

Look: good coffee beans are complete in shape and full in size. On the contrary, the shape is incomplete.

Pressure: fresh coffee beans are pressed fresh and crisp, and the fragrance floats out when they crack.

Color: dark black coffee beans, the coffee brewed has a bitter taste; yellow coffee beans, the coffee brewed has a sour taste.

Good coffee beans, neat shape, bright color, roasted by single stir-fry. After brewing, the flavor is mellow and the stamina is strong; the bad coffee beans are of different shapes and incomplete. It is not mellow enough to talk about fragrance after brewing.
