When considering coffee storage, keep in mind the two main enemies of fresh coffee flavor – air and moisture. Your coffee storage solutions should prevent either from getting at your coffee beans.
1. Don’t store ground coffee. Buy your coffee as whole beans, and grind it when you’re ready to brew. If you do buy ground coffee for the convenience, store it at room temperature in an airtight container after it’s been opened. A ceramic canister with a vacuum seal is a good choice – but avoid clear glass. Sunlight and heat are not good for your coffee.
2. Store up to a one week supply of whole coffee beans in an airtight canister at room temperature. You can use those pretty ceramic canisters, but they’re really not necessary. Any canister that you can seal with an airtight seal is fine, including the can that you bought it in.
3. If you find yourself with more coffee than you’ll use in one week, you can store up to another week’s supply in the freezer – but you should take some precautions to keep the air and moisture away from it first. Here’s how to store coffee safely in your freezer:
- Put the beans in an airtight canister.
- Or – put the beans in a zippered plastic storage back. Whoosh out all the extra air, or use a straw to suck it out. Then wrap the bag in one or two layers of plastic wrap and finish up with a layer of aluminum foil.
- Either way, once you take the canister or package out of the freezer, don’t put it back in. Refreezing your coffee will only dehydrate it and hasten the flavor decay.
You may also use a vacuum sealer to store your coffee beans. I highly recommend it
