How to Store Coffee Beans Once Opened So They Stay Fresh

You’ve just cracked open a fresh bag of beans. Maybe it’s our best-selling Prime, a juicy micro lot, or a single origin that’s been calling your name all week. That first whiff? Roasty, rich, full of promise. But here’s the thing: once those beans hit the air, the clock starts ticking. Oxygen, light, and moisture all work against you, stealing the flavour and aroma that make great coffee worth sipping.

The good news? You don’t need fancy gear or barista-level skills to keep your beans in top shape. With a few simple tweaks to your storage routine, you can keep that bold, complex flavour locked in for longer. Here's how to store coffee beans once opened, so they stay fresher and your morning brew keeps hitting the mark. Cup after cup.

1. Keep Them in an Airtight Container (No, the Bag Doesn’t Count)

Once you open your bag of coffee, oxygen becomes the enemy. The more air your beans are exposed to, the faster they go stale. That’s why for coffee beans storage, we recommend transferring them to an airtight container, preferably one that’s opaque or UV-blocking. Light and air are flavour thieves. Keep them out.

2. Store Them Somewhere Cool and Dry

Think pantry, not fridge. Coffee beans are sensitive little things. They don’t love heat, moisture, or big temperature swings. A cupboard away from your oven or window is ideal. Bonus points if it’s at a consistent temperature and humidity.

3. Please Don’t Put Them in the Fridge (Or Freezer)

We get asked this a lot: “Should I keep my beans in the fridge?” Short answer? No. Coffee beans are porous, which means they can soak up moisture and odours from whatever else is nearby, be it garlic, onions, or last night’s leftovers. That’s a no from us. 

Freezing is better than refrigerating, but only if you vacuum seal the beans. Otherwise, if you really care about keeping your coffee beans fresh, skip it.

4. Buy Smaller Amounts More Often

One of the best ways to keep coffee fresh? Don’t let it sit around too long. Buying smaller batches more regularly means your beans don’t have time to go stale. And if you’re a regular sipper, our coffee subscriptions make it easy to stay stocked without hoarding. You’ll always have fresh beans on hand, without overdoing it. Buy coffee beans or set up a plan that works for you.

5. Grind Right Before You Brew

Pre-ground might be convenient, but it’s no match for freshly ground beans. Grinding right before you brew preserves the aroma and flavour that makes each cup sing. If you're experimenting with flavour or technique, check out our guide to the different ways to brew coffee. You might just discover a new favourite method.

6. Want to Store Beans Longer? Go Vacuum-Sealed

If you're stocking up or saving a special roast, vacuum-sealing can help extend freshness. Just be sure to keep it in a cool, dark spot and only break the seal when you're ready to use the beans. And if you're buying in bulk for your café, we've got you covered. Our wholesale coffee suppliers program is built to keep businesses brewing bold, fresh coffee every day.
