Filter-hanging coffee can be regarded as a great invention of human beings. it is of great help to many people who do not have an Italian coffee machine or a grinder at home, but when brewing filter coffee, there is often the problem that the taste is too weak or too strong. how much water should be suitable? Is there any way to make coffee taste better? these are mainly problems in brewing coffee.

Even if the filter-hanging coffee is simple enough, we still need to pay attention to the perfect taste, so many people will make a cup of filter-hanging coffee before going to work every day to explore whether there is anything that needs to be corrected today. So I will sort out a few points here for your reference. You can make your own corrections according to my suggestion. After all, your tongue is not equal to my tongue.

The production of the earbag will first grind the coffee beans into coffee powder, which will greatly increase the surface area of the coffee in contact with the air, so it is not easy to preserve, and the best taste period will be shortened to about two weeks.

Even using vacuum packaging can not stop the disappearance of coffee aroma, because coffee beans will continue to function and release carbon dioxide after baking, so most of the earbags will appear a little bulging. This means that this bag of coffee is packaged when it is fresh, and when the carbon dioxide in the coffee is released (about two weeks), the aroma will begin to be released, and there is no change on the surface. However, the coffee has slowly deteriorated. If you leave it at room temperature for more than two weeks, there may be little aroma left, but because the earbag is sealed, you can still smell the fragrance when you open it, but it is not so fragrant after brewing.

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 (or some). Many people will test the taste by squeezing the breather valve, while squeezing out the fragrance, it also shortens the life of the coffee. 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 drink the earbag 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.
