How To Store Coffee Beans And Grinds So They Stay Fresh

Storing coffee beans and coffee grinds so they stay fresh for flavour is a vital part of brewing the perfect coffee every time.

Coffee storage is just one of the many ways to make sure your coffee is as good as can be as early as possible but picking the right roast for your brewing method is key. Buy a dark roast for >espresso-based coffees, for example, while filter coffees like a Chemex are best made from medium and even light roasts.

Once you’ve bought the right beans for your brew, how should you store them and keep them fresh for the perfect coffee taste?

Read on.

Keep your coffee airtight.

Once your coffee’s been roasted, it’s vital that you keep it as fresh as you can. This is why coffee beans are generally immediately packaged into the heat-sealed bags that you’re used to getting upon delivery or purchasing from a café or store. Once those bags are opened, make sure that your coffee beans or grinds stay in an airtight container.

If you’re only ordering 250g of coffee beans at a time, storing them inside your espresso machine hopper is a good option if the hopper is large enough. Most espresso machine hoppers are large enough to hold around 200g of beans. For the rest, make sure to keep them airtight.

Your coffee bags might come with a resealable zip to keep your beans fresh. Make sure that no air is leaking through those zips if you have coffee beans in those kinds of resealable bags.

Otherwise, coffee tins or even good Tupperware or Pyrex containers are a great option for keeping your coffee airtight.

Remember: keeping your coffee fresh is the goal. Fresh coffee means flavourful coffee and if it dries out you’ll be drinking coffee that may as well be instant.

Buy the right amount.

One way to make sure that you only have as much coffee as you’ll be able to drink before it goes stale is to make sure you buy the right amount of coffee as you need it.

That means only buying 250g bags of coffee beans or grinds if you’re not a daily drinker. It means only buying one or two kilos at a time if you are a daily drinker. This means that trying to stock up on bulk coffee — like ten kilos at a time — might be a bit cheaper but it will likely mean that your coffee’s not as good as it should be when it comes time to brew.

The average espresso shot requires about 7g of ground so work backwards to find out what you need. That is: 250g of coffee will make about 35 shots. If you drink strictly one shot per day, that’s enough for a month. If, like us, you drink more than that you should be buying 1kg bags.

If you’ve planned ahead but you somehow still have too much, you still have options.

If all else fails, freeze.

If you’re not drinking through your coffee fast enough, if you’ve run out of Tupperware containers, or if your coffee tin’s already full you can freeze your coffee beans and grinds.

To freeze your coffee, make sure that you place it in an airtight container to avoid freezer burn on your beans from condensation that might squeeze through. Keep available what you might use for a week and freeze the rest.

Frozen coffee can stay good for about a month but make sure that it’s in something airtight and a bit isolated. Coffee beans absorb moisture, flavour, and odour from foods around them so make sure your coffee isn’t accidentally also onboarding the taste of your other frozen food.

If you’re freezing beans rather than grinds, note that whether or not they should defrost can depend on your intended brewing method. For espresso coffee, you can grind straight away. For filter coffee, some baristas prefer to let them thaw some. You can use grinds straight from the freezer straight away.
