Teach you how to choose fresh coffee beans to smell, see and peel.

Freshness is the life of coffee, how to determine the freshness of coffee beans, there are three steps: smell, see, peel.

► smell

Put the coffee beans close to the nose and take a deep smell to see if you can clearly smell the aroma of the coffee beans. If so, it means the coffee beans are fresh enough. On the contrary, if the aroma is weak, or if the smell has begun to appear greasy (such as peanuts or nuts will appear for a long time), 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.

Spread the coffee beans on your hands, determine the origin and variety of coffee beans, and 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 beans are not fresh, you will find that you have to work hard to get rid of a bean.

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