The packaging of many coffee beans on the market will be equipped with breathable valves, so that the carbon dioxide of coffee can be released to prevent the packaging from breaking due to the expansion of carbon dioxide. on the one hand, it can prevent a large amount of air from entering (some will go in). Many people will test the taste by squeezing the breathable valve, which shortens the life of the coffee when squeezing out the fragrance. If the ear bag is equipped with a breathable valve, it is not only costly, but also unable to prolong its best taste period.

Therefore, it is best to finish the hanging-ear coffee within two weeks. if you can't finish it within two weeks, you should put it in the freezer as soon as possible. For example, if you buy 20 bags of earbags at a time and drink 5 bags in two weeks, put 15 packets of ice in the freezer on the day you buy it back, which can slow down the deterioration of those 15 packets of coffee, although the fragrance will fade a little. It is best to reheat for about half an hour before brewing, or put it in the freezer the night before.

You can also refer to the baking date and shelf life indicated in the hanging ear package, but it is suggested that the best taste period is within a month. After more than a month, the fragrance has disappeared, but it is still drinkable.
