Coffee common sense how long can coffee beans or coffee powder be kept?

Retention period and renewal are important matters.

Roasted new coffee beans will begin to drain (mainly carbon dioxide). The roasted beans will discharge the most in three days and have been preserved for about a week. To put it more seriously, after the complete arrangement, the coffee beans are no longer new, and this process usually requires a lot of money. In other words, it is the best time limit.

The mass-produced coffee beans are all based on the central roasting model, sole. It takes as little as a week for private merchants, but the average delivery time is a few months, and the shelf life of mass-produced coffee beans is usually between one year and 18 months.

In 1999, the American Fine Coffee Association (SCAA) defined "freshly baked coffee" as follows: no matter how it is packed, it must be soaked within three to seven days after baking, and it must be soaked immediately after grinding. The conclusion made by Don Holly, president of SCAA, is that this is not what coffee and bean producers like, because their distribution systems usually fail to deliver beans to consumers within a week.

How long can coffee beans and coffee powder last?

It really depends on the degree to which a person is required to drink coffee. Based on the difference in people's sensitivity to smell and taste, how many people can tell the difference between one and the other, or the difference between a month and a month? Therefore, as long as you know how to preserve coffee beans, one month is generally acceptable.

The shelf life of coffee powder is very short. After grinding into powder, due to the increase of surface weight and the acceleration of oxidation, a large amount of aroma and flavor will be lost. Therefore, unless you have to, for example, in the office, when you can't grind the beans, it's best to buy fresh coffee beans and grind them before drinking them.
