If you’re anything like us, you have probably spent hours researching into coffee, how to brew it, ideal temperatures and times, the best coffee beans to use, all in the pursuit of that perfectly balanced brew (or maybe that’s just us!). It seems silly that after all that effort you would overlook the seemingly small detail of how to store your coffee. And yet this detail can make or break your whole experience because good coffee comes from good beans. And good beans not stored correctly will quickly turn to bad beans. We have compiled a list of the best coffee canisters to keep your beans fresh.
Our Pick: Coffee Gator Coffee Canister
If you are in a hurry our top pick is the Coffee Gator Coffee Canister. This is a sturdy, attractive, airtight container and it has the added features of a CO2 valve, free travel container and calendar wheel to help you keep track of how old your beans are.
Why Do You Need To Store Your Beans In A Coffee Canister?
The answer to this is simply one word: Freshness. Nothing can compare to the aroma and taste of a rich cup of coffee brewed from fresh beans. And yet this freshness can be fleeting as coffee has four enemies that rob it of its delicious qualities: Oxygen, Moisture, Heat and Light.
Oxygen
Coffee beans lose their flavor when they come into contact with oxygen in a process known as oxidation. This is the same process that causes metals to rust, fruit to brown, or in our case coffee to stale. Oxygen causes the aromatic compounds in coffee to deteriorate.
Carbon dioxide (which is released from beans after being roasted) is a friend of coffee. It slows the effects of oxidation helping preserve its flavor. That is why older beans, that release less CO2 have a weaker flavor.
Moisture
Coffee is hygroscopic (wrap your laughing gear round that word!). This basically means it absorbs moisture very easily. Moisture on the surface of a bean will cause the aroma and flavor of the beans to leak out.
Heat
When coffee beans are heated too much, the oils (which contain a lot of the flavor) start to leak out onto the surface of the bean and quickly evaporate. The optimal storage temperature is at room temperature, around 20-25 degrees Celsius. Store beans in a cupboard or pantry ideally on a low shelf (as hot air rises) away from the stove/ microwave.
Light
Light (particularly UV rays) cause the breakdown of chemical compounds in coffee and thus degrade the quality of your bean.
Overexposure to any of these will cause your beans to go stale as CO2 escapes and the beans oils evaporate. It’s these oils, and also the CO2 that you want to extract to produce that rich, crema topped espresso.
What To Look For In A Coffee Canister?
Airtight
The most important consideration is that a coffee canister should be airtight to reduce the rate of oxidation. Some containers also come with a one way valve that allows CO2 to be released- this is not hugely important unless you are a home roaster. This is because the biggest release of CO2 occurs 24-48 hours after roasting. You will see that many coffee bags contain the same valve however this is to prevent the buildup of CO2 which could cause the coffee bag to explode.
UV protection
Given how quickly beans can break down when exposed to UV light it is best to opt for an opaque coffee canister that prevents light from entering.
Size
Think about how many beans you will need to be storing and buy a coffee canister to suit that capacity. You don’t want to get a container that is too large or all the extra space will be filled with oxygen defeating the purpose.
Aesthetic appeal
If you are going to have your coffee canister sitting on your bench you want it to look good and match the style of your kitchen.

It also features a 2 way valve allowing CO2 to escape.

Cons:
- Made of plastic
- Not that aesthetically pleasing

Other Tips To Keep Beans Fresh
- Buy whole beans (as opposed to pre-ground). Ground coffee loses its freshness far quicker than whole beans given it has a much larger surface area for oxidation to occur. For the best tasting coffee it is better to buy whole coffee beans and ground them when needed.
- Grind coffee right before you brew. Ground coffee loses its freshness within 3-5 minutes of grinding.
- Store at room temperature between 20-25 degrees. Do not store beans in the fridge or freezer. This can easily result in the build up of condensation on a bean and damage the integrity of the coffee. In addition coffee beans absorb the flavor of the surrounding environment so unless you like a fishy flavor profile to your brew…
- Buy small quantities of beans on a regular basis. Basically roasted beans retain their maximum flavor for about two weeks after roasting, are still relatively flavorful for 2-4 weeks, and anything after a month start to go stale. So it is best to buy small batches (depending on how much you drink!) regularly rather than large batches occasionally.
- Top up your hopper regularly (as most hoppers are not airtight)
