The cellular structure of roasted coffee will take on any funkiness of the fridge so don’t store your coffee there. The freezer can store coffee well — if you can keep it in a laboratory state and not let it become freezer burned. Plus, as you keep taking out the coffee to use, it thaws slightly and pulls oils to the surface. Over the course of the pound it will deteriorate very rapidly, becoming brittle for the grinder. If you use the freezer, take out only what you need and put the rest back ASAP. Use the coffee right way — when it thaws it wants to oxygenate very fast. 

The best place is a dark container you can seal well. In other words, just leave it in the special KHC bag, put an elastic band around it and put it in a cool, dark, dry place.
