How long is the best time to use up fresh coffee beans-how many days can they be stored?

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. 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.

Coffee should be stored in a dry, cool place, not in the refrigerator, so as not to absorb moisture. Coffee beans and ground coffee can be frozen, but the only thing to note is that when you take the coffee out of the freezer, you need to prevent the frozen part from melting and dampening the coffee in the bag. Americans think coffee is better in the refrigerator. But it won't take more than a month. They took out the amount of coffee beans they wanted to drink from the freezer and began to grind and boil them to drink before they thawed.

Packaging that helps store coffee

Tin cans can keep the aroma of coffee for a long time. Plastic bags are fine, but they store less than tin cans. In foreign countries, coffee beans are sometimes sold in tin cans or plastic bags. Vacuum packaging is more conducive to the storage of coffee, making the original flavor more lasting.

Once you open an oil-proof or tin foil-wrapped coffee bag, immediately put the coffee beans or coffee powder in a sealed can; the coffee powder will not get moldy quickly, but will absorb the smell from the air just like coffee beans.
