5 Ways to Keep Your Coffee Beans Fresher, Longer.

If you’ve ever found yourself asking, “Why do my coffee beans taste stale?” or “How long do coffee beans last?”, freshness might be the culprit.

Here are five ways to preserve your beans for maximum flavour:

1. Store in an Airtight Container

Exposure to oxygen is one of the quickest ways for coffee beans to lose their flavour. Also, roasted coffee beans are Hydroscopic meaning they take on moisture from the environment around them so leaving them in poor storage will lead to them staling faster. Use an airtight container, like our Airscape canisters, which keep beans fresher by locking out air and light.

2. Keep Them Away from Heat and Light

Heat and light can degrade coffee beans, making them stale. Store them in a cool, dark place like a cupboard away from heat sources to preserve their flavours. Most importantly the temperature should be stale, studies have shown that fluctuations in temperature are what cause the most damage to coffee beans in storage.

3. Buy in Smaller Quantities

Buying smaller quantities frequently ensures your beans stay fresh. Ideally you want to be consuming your coffee 7 days after it was roasted and trying to get through it before its a month old - this is more important for espresso and not such a problem for something like pour over or french press)

If this method appeals to you, consider a fortnightly subscription. This not only maintains peak freshness but also you get the most variety, as we feature a different roaster every fortnight.

4. Grind Just Before Brewing

Freshly roasted coffee beans begin to lose volatile aromatic compounds the second they are ground. Studies show that the largest percentage of these compounds is lost within the first 15 to 30 minutes after grinding. To prevent rapid flavour loss, grind your coffee only before you brew.

If you use an espresso machine, you can take it one step further with single dosing. Keep your beans in an airtight container like an Aiscape canister, and use scales to weigh out only what you need (typically 18-20g per espresso shot).

5. Freeze Beans for Long-Term Storage

Freezing can extend the lifespan of coffee beans. If you want to freeze an open bag, try to expel as much air as possible or use a vacuum sealer. When taking beans out of the freezer, let them thaw completely before opening the bag to avoid condensation, which can degrade the beans' quality.

How Long Do Coffee Beans Last?

In ideal storage conditions, whole coffee beans remain at their freshest for 2-3 weeks after roasting but can be used for a couple of months - You will find espresso shots begin to brew very fast and lose texture but there is nothing "wrong" with the coffee.

By following these tips, you can enjoy your freshly roasted coffee beans for longer and ensure every cup is rich in flavour.
