You've bought your delicious, super-fresh coffee from your local roaster, and can't wait to rip open the bag to drink it. So you open it up, grind, brew, and enjoy every life-giving drop. Now, if your roaster has packaged the coffee in a bag with a valve and a zipper closure (like ours), it can stay in the bag happily at room temperature. The valve is meant to expel the CO2 that coffee naturally releases after roasting. It is a one-way valve that never allows the coffee to be in contact with oxygen, and going stale.
If the coffee bag doesn't have a valve and zipper closure, your best option would be to seal it in a glass or stainless steel airtight container ONLY if you will be consuming the coffee regularly. There are many coffee-specific containers on the market, some even with a built-in vacuum sealer.
We do not recommend storing coffee in the freezer or refrigerator. Condensation can accumulate, and the coffee can sweat oil, which will make the coffee go rancid. Coffee should be consumed as soon as possible, preferably within 2 weeks for a 12 ounce bag.
