What is the knowledge of boutique coffee beans? What is "new bean"?

Just like rice has new rice, old rice, old rice, coffee also has new coffee, old coffee, old coffee. The new coffee is called "new bean", which refers to the coffee raw beans harvested that year (now the coffee in Yunnan is ripe, don't miss it). The raw coffee beans produced the year before were called "Past crop". The raw beans harvested in earlier years are called "old beans".

Some shops in Japan, under the name of old beans, put the raw coffee beans like wine in a constant temperature warehouse for several years before they are roasted. In fact, in Europe and the United States and other developed countries, only the new beans produced in that year are high-grade products, because the taste and aroma of new beans are excellent.

Putting the wine in a bottle can ripen the wine because of the production of yeast. It is impossible for him to mature the shelled coffee beans no matter how they sit, because the germ in the seed has been removed and will not germinate even if it is planted in the soil. Coffee producers usually keep coffee beans in a shelled state, shelled and then exported. The freshness of coffee can be preserved more or less by storing dried fruit (Dry cherry) or shell beans.
