Freshness is the life of coffee

Smell: just to see if you can smell the aroma of coffee beans. If you can, coffee beans are fresh enough. On the contrary, the fragrance is weak or greasy, indicating that the coffee beans are completely stale. 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: if you pour the coffee beans on your hand, you can determine the origin and variety of the coffee beans, and also determine whether the coffee beans are roasted evenly.

Peel: 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 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 thing to peel 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.

The difference in taste between large coffee beans and small coffee beans

For the same kind of coffee, the bigger the bean, the higher the grade, the smaller the bean, the lower the grade, and the cheaper it is. Of course, there are differences in taste. The bigger the beans, the stronger the coffee. However, in addition to high-grade products, the classification of other coffee is not very strict, for example, the central grade beans can account for 60%. Then beans one level higher than this level and beans at a lower level will each account for 20% at the same time. Therefore, sometimes it is roasted according to the standard of the marked central grade, and the other 40% of the coffee cannot be roasted under the best conditions.

The division of new beans and old beans in coffee beans and the time to market

The taste of new coffee and old coffee baked in the same variety and degree will be significantly different, of course, new beans are more fragrant. Although the moisture of the new bean will be greatly lost and the color will turn white after several years of preservation, the fragrance will not be greatly affected.

Small coffee beans still have so much knowledge ah, it is really shocking!
