Freshness is the life of coffee how to choose coffee beans
"freshness is the life of coffee. How to determine the freshness of coffee beans?"
There are three steps: smell, see, and peel.
◎ smell: hold the coffee beans close to your nose and take a deep breath to see if you can clearly smell the aroma of the coffee beans. If so, the coffee beans are fresh enough. On the contrary, if the aroma is weak, or has begun to appear greasy, 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: spread the coffee beans on your hands, determine the origin and variety of coffee beans, and determine whether the coffee beans are roasted evenly.
◎ peel: take a coffee bean and try to peel it off with your hands. If the coffee bean is fresh enough, it should be easy to pull away, and it will have a crisp sound and feel. 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.
The difference between the taste of ☆ 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.
Division and time to market of new beans and old beans in ☆ coffee beans
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. "
