Freshness is the life of coffee, but how to determine the freshness of coffee beans?

Grasp the three main points: smell, see, and peel!

◎ smell

If you put the coffee beans close to your nose and take a deep breath, you can clearly smell the aroma of the coffee beans. If so, it means that the coffee beans are fresh enough. On the contrary, if the aroma is weak, or if the smell has begun to appear greasy (like peanuts or nuts, it will appear for a long time), it means that the coffee beans are not fresh at all.

No matter how much effort you put into grinding and cooking such coffee beans, it is impossible to make a good cup of coffee.

◎, look.

Pour the coffee beans on your hands and spread them out to see the color and oil of the coffee beans. You can also determine whether the coffee beans are roasted evenly.

◎ peeling

Take a coffee bean and try to peel it off by hand. if the coffee bean is fresh enough, it should be easy to pull away, and it will have a crisp sound and feeling; if the coffee bean is not fresh, you will find that it seems to take a lot of effort to pick a bean.

Another important point to observe when peeling off the coffee beans is to see if the firepower is uniform when baking. If uniform, the color of the outer skin and inner layer of the beans should be the same, and if the color of the surface layer is obviously much darker than that of the inner layer, it means that the firepower during baking may be too large, which will also affect the aroma and flavor of the coffee beans.
