About the storage of coffee beans

The ideal way to buy and brew coffee is to buy large quantities of green coffee, roast it yourself, and grind it before preparing it for brewing. But most people like to buy coffee beans that have been roasted, and probably buy more than we use for days.

Water is the enemy of coffee storage. Coffee oil is water soluble. It adds flavor to coffee, while moisture spoils coffee oil. Don't store coffee in the safe of the refrigerator because moisture condenses on the container surface when the refrigerator is opened.

For long-term coffee preservation, it is best to wrap them in airtight bags and store them in the refrigerator. Roasted coffee beans should be kept for more than a week. There is no need to defrost them for grinding-they can be put directly into the grinder.

Another enemy of coffee beans is oxygen, which oxidizes volatile odors. That's why coffee is ground before it's brewed. When coffee beans are ground, most of their surface is exposed to air. This means that the coffee oil starts to evaporate and the taste will gradually disappear in the thin air.

Do not place coffee near other strongly odorous items such as tea. Because coffee absorbs other odors quickly, keep coffee in a clean, airtight container.

If you're ordering coffee, don't buy too much at once. Although buying coffee in bulk saves money, coffee loses its value when it loses its flavor.
