On the average, ground coffee should keep fresh for around a week if it is stored in an airtight container. To get the freshest, buy coffee beans that have a recent roast date, such as within the last week or two.
Coffee beans that are stored properly will keep fresh for around nine months. However, the quality of the beans slowly degrades over this time. If you store your ground coffee in an airtight container, it will keep for an additional two months.
Freezing coffee preserves its flavors and smells for a longer time, but kills the vitality of the coffee. Condensation of water occurs within the coffee because of the freezing temperature. When exposed to the freezer, the coffee will acquire unpleasant aromas.
But keeping your coffee fresh isn't only about storage; it's also about preparation and packaging. Because some coffee isn't made to last. It's best to restock periodically rather than wait.
Pre-ground or home-ground coffee lasts less than coffee beans. Coffee grounds have a considerably larger surface area and the centre of the bean is not protected. However, careful packaging and processing can minimize this disparity.
Some coffee companies use nitrogen flushing, which involves packaging newly roasted coffee beans and then flushing the box with nitrogen, which does not stale the beans.
Placing the coffee beans in a vacuum-sealed container essentially does the same thing as storing coffee in an airtight container, except that all of the gasses are sucked out of the package first, leaving no oxygen in the package rather than the small quantity of oxygen remaining in an airtight container after the coffee is sealed.
While our tongues are only capable of distinguishing between sweet, sour, bitter, savory, and umami, our nostrils are capable of detecting whether or not the coffee beans are rotten just by smelling them. It is likely that the coffee will taste flat if they smell flat.
