The preservation method of high-quality coffee beans is suitable for the storage of coffee.

Coffee should be stored in a dry, cool place, not in the refrigerator, so as not to absorb moisture. Coffee beans and ground coffee can be frozen, the only thing you need to pay attention to is that when you take the coffee out of the freezer, you need to avoid the frozen part from melting and damp the coffee in the bag. Americans think coffee is better in the refrigerator. But it won't take more than a month. They took out the amount of coffee beans they wanted to drink from the freezer and began to grind and boil them to drink before they thawed.

With the increase of time and processing procedures, the life of coffee will be reduced; the appropriate storage method can prolong the shelf life of coffee. Packaged tin cans that help coffee storage can keep the aroma of coffee for a long time. Plastic bags are fine, but they store less than tin cans. In foreign countries, coffee beans are sometimes sold in tin cans or plastic bags. Vacuum packaging is more conducive to the storage of coffee, making the original flavor more lasting. Once you open an oil-proof or tin foil-wrapped coffee bag, immediately put the coffee beans or coffee powder in a sealed can; the coffee powder will not get moldy quickly, but will absorb the smell from the air as well as coffee beans. The storage of coffee beans the heavier the unroasted or fried beans are, the better. Once the coffee beans are roasted, they will slowly lose their fragrance, and the fragrance will be gone after two weeks. So buy a small amount at a time, or a small amount of ground coffee. If you mail-order coffee from a coffee bean store, you'd better buy unground beans. Storage of instant coffee
