Cafephile Lesson #1
How long is coffee good for? Does coffee expire? How to make it stay fresh longer?
That depends on what type of coffee you have. All coffee should be stored long term between 50 and 70 degrees Fahrenheit, at about 30 to 50 percent humidity. If you have green coffee beans they should be stored to the open air (example, burlap bag) and are good to roast for 2 to 4 years, depending on humidity. Keep them dry and away from water and sunlight. Roasted coffee beans should be kept in an air tight container, as well as ground coffee. You can store roasted coffees without much flavor loss for about a year unopened, or 2 years in the freezer. Coffee is still good past these dates if kept properly, but flavor fades away quickly over time. Once you open roasted beans or ground coffee you should plan to use it up within a 4 weeks for the best flavor.
