Coffee starts losing flavour the moment it's exposed to air. The MiiR Airlock Coffee Canister addresses this with a press-to-seal inner lid that pushes excess air out of the canister each time you close it, helping your beans or ground coffee stay fresher for longer between brews. The canister holds approximately 340g (12oz) of coffee and is made from 90% recycled 18/8 stainless steel. Its minimalist black finish suits a home kitchen, office counter, or cafe coffee station without drawing unnecessary attention. How it works Inside the canister sits a floating seal disc. Press it down after adding your coffee, and it forces air out through a one-way valve, reducing the oxygen that would otherwise degrade flavour and aroma. When you're ready to use the coffee, pull the centre knob upward to release the seal and lift the plunger out of the canister lid. This makes the canister suitable for both whole beans and ground coffee, whichever you keep on hand.

If you buy coffee in 250g-340g bags and go through it within a few weeks, this canister is a straightforward way to keep those beans in better condition than the original bag alone. It won't stop staling entirely, coffee is best used within a few weeks of roasting regardless of storage but reducing air exposure is one of the more effective things you can do to slow the process at home.
