    Storing your coffee in an ordinary tin with a clasp? Maybe just a typical jar? Fresh coffee is a thing of wonder, but the further the grounds are from their roasting and grinding date, the more the flavour disappears.

    Surrounding moisture, oxygen, heat, and light all affect the taste and strength of coffee beans and grounds.

    To keep them at their best, storing them in an airtight coffee container is your best option.

    Here’s all you need to know when shopping for airtight coffee containers in the UK, including our Top 3 Picks based on the material, size, airtight technology and features like a CO2 release valve.

    Coffee Container Buying Guide

    What makes a good airtight coffee container?

    Keep your coffee in an ordinary tin with a clasp? Maybe just a normal jar? Here is why an airtight coffee canister is important and sets them apart from the rest when it comes to your fresh coffee:

    • Material – Stainless Steel is the best as it keeps out moisture and is resistant to changes in external temperature, while being easy to clean and it also stays clean.
    • Co2 Valve – We have explained below why this is important, but it helps when the coffee is ultra-fresh.
    • Date Wheel – You can either make a note of when you bought the coffee, or when you feel you want to make a fresh batch. Ground coffee can usually be kept for around two months.
    • Airtight – Oxygen can damage the quality of coffee, but other environmental aspects such as moisture and heat can also have a negative effect so it is important to guard the coffee


    How much coffee do you need to store at any one time? If you bulk buy, or ground and roast enough for a few weeks at a time, look for an airtight coffee storage container on the larger side.

    But if you like to keep on top of this all to preserve freshness, a small canister could actually be best. Remember that any spare space in the caddy will be taken up by CO2, and you want to limit the amount in the tub at any one time. If there is no room for it, it won’t exist.


    Why does coffee start to disintegrate?

    Whether it’s light, moisture or age, the flavour of your coffee can really start to wear away as soon as it is purchased.

    These external aspects can stale the coffee, and on top of this, humidity and temperature changes could even encourage mould to grow.

    On top of this all, coffee starts trying to destroy itself by releasing CO2. Whenever coffee beans are roasted, the heat causes carbon dioxide to become trapped in the bean. When ground, this by-product starts to escape even quicker, and if there is too much CO2 present in the coffee when hot water is used on it, it distorts the flavour.

    This is why both an airtight jar and a CO2 release valve are vital if your coffee is at its freshest.

    Is it best to store coffee as grounds or beans?

    Obviously this depends on your coffee making process. If you home grind your beans, then keeping them in their most natural state (the bean) is best because once they are ground, their shelf life starts to lower.

    But if home grinding and roasting is not for you, there is plenty of pre-ground coffee out there available in different sizes, depending on the machine you’re using. As mentioned above though, don’t store too much at once as it could mean more work looking after it.
