Fresh roasted coffee starts losing aroma soon after roasting. You can't stop that clock, but you can slow it down a lot with a few simple habits.
Coffee's four enemies
The National Coffee Association names air, moisture, heat and light as the biggest threats to fresh roasted flavor. Every storage tip below protects against one of them.
The best way to store coffee
- Use an airtight container. A sealed canister or the original bag rolled tight and clipped works well.
- Keep it dark. Choose an opaque container, or keep a clear one inside a cabinet.
- Keep it cool and dry. A pantry or cupboard away from the stove, oven and sunny windows is ideal.
- Buy what you'll use. Aim for an amount you'll finish in one to two weeks. A monthly coffee club makes this automatic.
- Grind just before brewing. Whole beans hold their flavor much longer than ground coffee.
Should you refrigerate or freeze coffee?
Coffee absorbs moisture and odors from the air around it. In the fridge, condensation and food smells are a real risk, so we don't recommend it. Freezing can help with a larger supply you won't open for a while, but only in a truly airtight container. Take out what you need quickly and don't refreeze beans that have thawed.
How long does coffee stay fresh?
For the best flavor, brew whole beans within a few weeks of opening the bag, and ground coffee within about one to two weeks. Older coffee is safe to drink, it just tastes flatter.
FAQ
Is the one-way valve on the bag important?
Yes. Freshly roasted coffee releases carbon dioxide, and the valve lets gas out without letting air in.
Whole bean or ground for freshness?
Whole bean. If you don't own a grinder, choose the grind that fits your brewer and buy smaller amounts more often. See our grind guide.
