Don't store your coffee in the fridge or freezer - really bad idea. Dark cool cupboard in a well sealed container will do.
Why not in the fridge please? Mine at home is a little colder than normal fridges and it keeps it much fresher than in a cupboard, and as long as it's in an airtight container won't pick up other smells.
The only problem is condensation, which I only have trouble with at uni. (I think the fridge is a little warmer there).
EDIT: I'm no expert, so if there is any concrete advice saying not to put coffee in the fridge i'll happily be persuaded to change
