Want to know how to store your ground coffee, so it can stay fresher for longer? From choosing the best airtight container to knowing where to store it, here's exactly how to keep your coffee tasting great.
Don’t let good coffee go bad. Learning how to store coffee properly is easier than you'd think, and it makes a real difference to every cup – and the start of your day.
Whether you prefer to grind your own coffee beans or opt for the pre-ground stuff, we've pulled together everything you need to know to keep your ground coffee tasting as fresh as possible, for as long as possible.
If the real issue is that you've got far too much taking over your kitchen cupboards, that's a problem we can help with that, too. We offer flexible short-term and long-term storage options, so your storage can be on your terms, and those bags of coffee you're not using yet don't have to live on top of the toaster.
Storing your coffee properly is a must for great coffee, so just remember the essentials:
Before we get into the how, it helps to know the why. Coffee has four main freshness killers:
Ground coffee is more exposed to air than whole beans, which means the same rules apply, just with a little more urgency. The best way to store ground coffee is to:
Oxygen and heat will make your coffee go stale faster, so opt for a container with a proper airtight seal that also blocks out any light. Ceramic or stainless-steel containers are the best pick, as glass and plastic can accelerate any staleness.
Since air, light, heat and moisture are all coffee killers, you want to pick a place to store it that’s safe from these elements. Aim to keep your ground coffee well away from the oven, dishwasher or toaster if you’re keeping it in your kitchen.
While the retail bag might look nice and seem like a good bet for storage since it can be sealed, it should just be a temporary home. Move your coffee grounds instead into a proper container to keep them fresh and preserve the flavours.
As we mentioned, since ground coffee has a much larger surface area than whole beans, it risks going stale more quickly. So, go for smaller bags more often to keep your ground coffee tasting the best.
Keeping coffee in the fridge is a bad idea, as it will soak up all the smells of your fridge and lose its own flavour and aromas thanks to the condensation that comes from opening and closing the door. Cheese-flavoured coffee? We're not too sure.
if you've got more coffee than you'll get through in the next few weeks, freezing is a solid way to keep it fresh, but only if you do it properly. Here are our top tips to ensure you’re preserving it properly in the freezer:
Make sure you’re separating your ground coffee into small, airtight (ideally vacuum-sealed) containers before freezing.
By only taking out what you’ll use in a week, you won’t risk wasting any thawed coffee you don’t use.
Once you take it out of the freezer, let the ground coffee come fully to room temperature before opening to avoid any condensation forming, which could ruin the flavours of the coffee.
Roast dates matter more than "best before" dates with coffee, so it's worth checking the bag before you buy, but as a rough guide:

Opaque glass, ceramic, or a non-reactive metal like stainless steel are all good choices for storing coffee. Avoid plastic where you can, as it's more porous and will hold onto old odours over time. The best containers also have a one-way valve built into the lid to let carbon dioxide escape without letting any fresh oxygen sneak in.
Your nose knows best. Fresh coffee has a noticeably strong, rich aroma the moment you open the container; so, if you can barely smell anything, that's usually the first sign it's past its best.
Storing coffee in the fridge is a no-go. It's a common instinct to keep coffee in the fridge to keep it fresh, but coffee isn’t like food. Ground coffee is porous and will absorb the stronger smells of the food in your fridge. Also, the cold and moisture in the fridge will ruin the flavours of your coffee by dulling them.
