How to Store Coffee Beans
Coffee Bean, Airtight and Cool
Storage is integral to maintaining your coffee bean freshness and flavor. It is important to keep coffee beans away from excessive air, moisture, heat, and light, in that order, in order to preserve bean fresh-roast flavor as long as possible. Coffee beans are decorative and beautiful to look at but you will compromise the taste of your coffee if you store your beans in ornamental, glass canisters on your kitchen counter top. Doing so will cause them to become stale and your coffee beans will quickly lose its fresh flavor.
Storage of Your Daily Coffee beans
It is important not to refrigerate or freeze your daily supply of coffee beans because contact with moisture will cause it to deteriorate. Instead, store coffee beans in air-tight glass or ceramic containers and keep it in a convenient, but dark and cool, location. Remember that a cabinet near the oven is often too warm, as is a cabinet on an outside wall of your kitchen if it receives heat from a strong afternoon or summer sun. The commercial coffee bean containers that you purchased your coffee in are generally not appropriate for long-term storage. Appropriate coffee bean storage canisters with an airtight seal are a worthwhile investment.
Buy Fresh ground Coffee Beans
It is wise to purchase ground coffee beans in amounts proportionate to how quickly it will used. Ground coffee beans begins to lose its freshness almost immediately after grinding so it is far better to purchase it in smaller quantities if ground. Purchase freshly ground coffee frequently and buy only what you will use in the next 1 or 2 weeks. And because exposure to air is your ground coffee's worst enemy, it is a good idea to divide your coffee supply into several smaller portions, keeping the larger, unused portion in an air-tight container.
Storage for Larger Quantities of Coffee Beans
If you've purchased a large quantity of coffee beans that you will not use immediately, small portions, wrapped in airtight bags, can be stored for up to a month in the freezer. Once you have removed them from the freezer, however, do not return them. Instead, move coffee beans to an air-tight container and store in a cool, dry place.
