Reply to the hot discussion on the storage of coffee beans

Many friends have worked at the bar, and some have been baristas for a long time. When it comes to storage, it's no big deal. As soon as some of our junior friends were on the road, they kept asking about the storage of coffee beans. I'm not a barista, and I'm not a bartender. I've just been in this business for a long time. Have their own coffee, hope to communicate with you, do not hesitate to give advice, if there are any mistakes, hope to point out the fallacy, thank you.

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 to note is that when taking coffee out of the freezer, you need to prevent the frozen part from melting and dampening 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.

Tin cans 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.

Coffee bean storage should pay attention to two points, the first is water, and the second is oxygen, which is the "natural enemy" of coffee bean storage. After opening the package, the coffee beans are digested by him as soon as possible.

Choose the right packaging or container and store it in the right space, that's what it is, but fresh coffee is extremely sensitive to the storage environment. In recent years, experts strongly recommend the use of aluminum foil packaging material (opaque) with one-way exhaust valve, which is praised and recognized by large manufacturers at home and abroad, blocking the invasion of oxygen and being able to exhaust carbon dioxide, greatly prolonging the honeymoon period of tasting fresh coffee. As for storage, it only needs to be placed in the shade where it is not susceptible to moisture and direct sunlight, cold storage or freezing is not absolutely ideal, excessive shrinkage of fiber, condensation of benign oil, peculiar smell in the refrigerator and temperature difference during extraction all have an important impact.
