Introduction of the best eating time and storage time of coffee beans after baking
Fresh period: from the end of the "fresh period" of about 2 weeks, the coffee beans in the bag gradually go down from the peak state. However, if it is properly preserved, the quality and flavor of coffee beans decline slowly in the first period of time, and the freshness of coffee beans is still at a high level. We call it a "relatively fresh period" for about one month. Every coffee lover and coffee shopkeeper should strive to use up the coffee beans purchased before the end of the "fresh period".
Disposal period: calculated from the end of the "fresher period" of about 4 weeks, the quality and flavor of ripe coffee beans has been much worse than before, it is difficult to act as the word "fresh", unable to meet the picky needs of professionals. However, it is OK to make some fancy coffee, such as refreshing coffee for family breakfast, black coffee for coffee shops, or blending milk, cream, chocolate sauce, etc., which need not be denied at all. We believe that this stage can be maintained for about a month, during which time we need to open the bag and use it as soon as possible, which can be called the "disposal period".
The total 10-week period from the latest fresh period everywhere is neither long nor short, and consumers should make good use of it. After the disposal period of coffee cooked beans, even if the bag has not been opened, but also a sharp decline in flavor, no sense of freshness, no taste value. This problem is distressing, because for any ordinary coffee consumer, there is absolutely no ability and technical means to achieve good storage of coffee powder, and test data from professional institutions prove that coffee beans are in the first five minutes of grinding. there will be nearly 50% of the active volatile aromatic substances escape. If you buy coffee powder (except filled with inert gas), do not expect too much on the taste and flavor, can only talk about convenience as the starting point. And buying the worst grinding equipment will be hundreds of times better than buying coffee powder directly. Enthusiasts should still settle down to learn how to grind coffee beans.
