Water is the enemy of coffee storage. Coffee beans are preserved.

The ideal way to buy and make coffee is to buy a small amount of raw coffee beans, bake them yourself, and grind them before preparing them.

Water is the enemy of storing coffee. Coffee oil is water-soluble, it makes coffee more flavor, moist environment will rot coffee oil. Do not store the coffee in the fresh layer of the refrigerator, because as soon as the refrigerator is opened, the moisture will condense on the surface of the container.

If you want to keep your coffee for a long time, you'd better put them in a sealed bag and put them in the freezer. Roasted coffee beans should be prepared in the same way if they want to be preserved for more than a week. There is no need to thaw at the beginning of grinding-it can be put directly into the grinder.

Another enemy of coffee beans is oxygen, which oxidizes volatile odors. That's why coffee beans are ground before making coffee. When the coffee bean is ground, most of its surface is exposed to the air. This means that the coffee oil will begin to evaporate and the taste will gradually disappear into the thin air.

Do not put coffee near other items with a strong smell (such as tea). Because coffee absorbs other odors quickly, please put it in a clean, sealed container.

If you want mail-order coffee, don't buy too much at once. Although it saves money to buy coffee in whole batches, it loses its value when it loses its taste.
