If the bag is opened, it is best to store them in an opaque, air-tight container, at room temperature. Avoid clear containers, which will allow light to compromise the taste of your coffee. If you do not have an appropriate air-tight container, our coffee bags are actually the second best option, just make sure the re-seal mechanism is closed properly. If bags are unopened, you can store the bags in a normal kitchen cabinet, but preferably not with other foods with strong aromas. They will stay fresh this way for about 4-7 weeks.
