Storage of coffee beans | how to store high-quality coffee beans after opening the correct storage method to avoid the loss of bad flavor of coffee beans

Preservation of coffee beans

The best drinking period of coffee beans is within one month after roasting, a month later, the flavor of coffee beans has been lost a lot and began to deteriorate, but if not preserved properly, the shelf life of coffee beans may be greatly shortened.

Generally speaking, professional coffee bean manufacturers will use bags with one-way exhaust valves to preserve coffee beans after producing coffee beans. Coffee beans stored in one-way exhaust valves are basically unable to touch the outside air, and the loss efficiency of aromatic substances in coffee beans slows down. However, after roasting, coffee beans will produce carbon dioxide, and some of the aromatic substances will be lost through carbon dioxide. Some manufacturers put coffee beans in sealed, high-pressure or low-temperature containers in order to slow down the loss of aroma from coffee beans.

The position of several small holes in the general coffee bean package is the position of the one-way exhaust valve.
