It is best to store coffee beans in a sealed bag.

The ideal way to buy and make coffee is to buy a lot of raw coffee, bake it yourself, and grind it before you prepare it. But most people like to buy roasted coffee beans, and they probably buy more than we use for several days.

Water is the enemy of storing coffee. Coffee oil is water soluble. It makes coffee more flavored, while moist conditions can corrupt coffee oil. Do not store coffee in the safety layer of the refrigerator, because as soon as the refrigerator is opened, the moisture will condense in 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 are to be preserved for more than a week. You don't have to thaw when grinding-you can put them directly into the grinder.

Another enemy of coffee beans is oxygen, which oxidizes volatile odors. That's why you grind the coffee before you make it. 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 bulk, when coffee loses its taste, it loses its value.
