How long can I keep coffee beans or coffee powder?

Shelf life and freshness are two different things.

Freshly roasted fresh coffee beans will begin to exhaust (mainly carbon dioxide), with the largest amount in the first two or three days, lasting for about a week. When the gas is completely discharged, the coffee beans slowly go downhill in flavor, a process that usually takes two to three weeks. In other words, roasted coffee beans start from the third day to the fourth week, which is the best time to taste.

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.

The Fine Coffee Association recommends brewing 3-7 days after baking.

In 1999, the American Fine Coffee Association (SCAA) strictly adopted the definition of "freshly roasted coffee": no matter how it is packaged, it must be brewed within 3 to 7 days of baking and immediately after grinding into powder. 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.

Because fresh coffee beans will slowly change in the process, after a long time of testing, most people can still accept fresh beans within a month, even 45 days in winter, still think it is delicious.

How long can coffee beans and coffee powder last?

In fact, it depends on the degree of individual requirements for the quality of coffee. Based on the difference in people's sensitivity to smell and taste, how many people can taste the difference between a week and a week, or a week 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, 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 no choice, such as in the office, going out, etc., it is best to buy fresh coffee beans and grind and brew them before drinking them.
