Like fine wine, for the best results you’ll want your freshly roasted coffee to breathe. Let it rest uncovered overnight, then seal it in an airtight jar and store it in a cool, dry place where the beans will be at their freshest for about a week. And not in the freezer, for god’s sake! Extreme cold can damage the oils and thus the flavors in roasted coffee. Also, the beans are porous and can absorb odors from whatever else is in your freezer.
