I recently decided that I want to grind my own coffee beans (since I've heard that it's way better that way) so I bought a nice Breville grinder. But it really only has the capacity to grind that day's worth of coffee. So I'm wondering what do I do with the other beans that I buy? I really do not have time to go to the store every other day to buy fresh beans, so how can I store my coffee beans so that they will not get bad/stale? Fridge? Freezer? Room temperature? What is best? Obviously an airtight container but aside from that?
