title_body: Does storing coffee in a freezer preserve freshness?
upvoted_answer: No. In fact it's likely to make your coffee taste bad, and gum up your grinder. You should store your coffee in an air-tight container, at or just below room temp (about 25 degrees Celsius). 
  
  Coffee can and will absorb all kinds of odors, and while your freezer probably doesn't smell like much, there are odors that will (at the minimum) dull the taste of the coffee. Additionally, when you take your coffee out to room temp, condensation kicks in which further degrades the beans and messes up your grind. Depending on your climate, the condensation can also invite mold. Yuck!
  
  The only time you should be freezing or refrigerating coffee is when you're doing so because you've created a desert with some :) Otherwise, dark air-tight containers are the best way to go, just store them in your cabinet.
  
  A good rule of thumb: Store anything you buy the way it was when you bought it, unless the label tells you to do something different once you open it.
