The shelf life of coffee

Coffee without aroma has no meaning to exist. Therefore, the key to coffee preservation is how to best retain the aroma components in the coffee.

Coffee beans retain aroma ingredients much more easily than coffee powder. For coffee shops, purchasing coffee beans is a basic way to preserve the aroma of coffee. As far as families are concerned, buy coffee beans instead of powdered coffee as much as possible. If you have no choice but to buy coffee powder, be careful not to buy more coffee powder than you can use in 1-2 weeks. Otherwise, the coffee you make will not have the flavor it should have. You should buy coffee beans from the seller as much as possible and ask the seller to grind the coffee beans into powder according to the production equipment you use. To avoid buying coffee powder that has been on the shelf for a long time, such coffee powder has lost a lot of aroma ingredients.

The shelf life of coffee

In general, the "shelf life" mentioned in coffee packaging means that the aroma components of coffee can be retained to a certain extent. Not when the coffee may go bad. Because coffee is different from ordinary food, its humidity is very low and it is not easy to deteriorate.

After making coffee, the waste coffee grounds grow hairy because the coffee grounds become wet before they deteriorate and grow hair. If the coffee grounds are dried, there will be no long hair.

The shelf life of coffee in aluminum foil bags is 12-18 months. In the absence of an international standard in this regard, the shelf life offered by different coffee companies will vary slightly.

The preservation of coffee here refers to both coffee beans and coffee powder.

Many people keep their food in the refrigerator in order to avoid spoilage. The principle, of course, is to reduce the activity of food by lowering its temperature, so as to prolong its shelf life.

As we have mentioned above, unlike ordinary food, coffee has a very low moisture content and is not easy to deteriorate, and its shelf life is set for aroma. Therefore, putting coffee in the refrigerator is not good for it. On the contrary, it is easy to condense the residual moisture in the coffee package, greatly affecting the aroma components of the coffee. Coffee should be kept at room temperature, which is the experience people have summed up over the years.
