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. For coffee cooked beans that have passed the disposal period, even if the bags have not been opened, the flavor is sharply reduced, the freshness is gone, and there is 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 show that coffee beans will escape nearly 50% of the active volatile aromatic substances within the first 5 minutes of grinding. 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.

Mass-produced coffee beans operate in a central baking mode, which takes as little as a week for dealers, but the average delivery time for the industry is two months, while the shelf life of mass-produced coffee beans is usually between one year and 18 months.

In 1999, the American Fine Coffee Association (SCAA) adopted the definition of "freshly roasted coffee": no matter how it is packaged, it must be brewed within three to seven days after baking and must be brewed immediately after grinding. Don Holly, president of SCAA, concluded that this is not what mass-produced coffee beans want to hear, because their distribution systems are usually unable to deliver beans to consumers within a week.

The shelf life of coffee powder is very short. After grinding into powder, as the surface area increases, oxidation is accelerated, and a large amount of aroma and flavor will be lost within a few minutes. Therefore, unless you have to, for example, when you can't grind beans in the office or out, you'd better buy fresh coffee beans and grind and brew them before drinking them.
