We all love a good cup of coffee; whether it is to get you going first thing in the morning, an afternoon pick-me-up, or a social catch up with friends.
When you buy your coffee beans or grounds you want it to be good to the last drop. That perfect cup full of flavor and a rich, dynamic aroma can be yours whenever you please.
However, that is only possible if you are careful on how you store those coffee beans or grounds between pots of coffee. They don’t last forever… and the longer they sit, the poorer the quality.
There is a simple solution to keeping your coffee tasting its best. The type of container you use to store your coffee has a huge impact on what your next pot will taste like.
If you want to keep your coffee tasting its best, read on…
Storing You Coffee
The best way in order to store coffee and preserve the quality and flavor of the beans or grounds is in an airtight coffee container. That container should not be clear or see-through in any way.
Here’s how to store different types of coffee:
This is best used as soon as possible. The grinding action releases the flavor of the beans which means there is a small window where the flavor is at its peak. That is generally immediately after grinding. Using ground coffee much later will impact the quality of the brew.
Coffee beans that have been roasted have in a way locked in the flavor. The best way to keep them in their best condition is to store roasted beans in a cool, dark location. Keep them at room temperature.
Unroasted beans that you intend to use later will last longer if kept in an airtight coffee container. Keep that container in a location where the temperature and humidity are comfortable for you as well.
How Long Will Coffee Stay Fresh When Stored?
The answer to this question rests solely on how the coffee is stored. Here are some details:
Provided you have stored these beans in a location where light and oxygen cannot impact them, they will stay fresh for about 15 days. Grind them only just before you plan to use them.
Green Unroasted Beans
If you kept these away from light, air and humidity fluctuations, they can last for a year or more. Green beans can dry out in low humidity or develop mold in high humidity.
Can You Store Coffee In A Refrigerator or Freezer?
Sure you can store coffee in either of these– if you don’t like coffee that much. Storing ground or whole coffee beans in a refrigerator is an absolute no-no.
The reason for this is that in a refrigerator your coffee will be subjected to moisture. Moisture will destroy the integrity of beans and ground coffee very, very quickly.
As for storing coffee in a freezer, this is still not a very good idea. Well, at least if you plan on long-term storage as the intense cold temperature is not good for coffee grounds or beans.
There is an exception. You can store small quantities for use later but only in heavy-duty freezer bags and for no more than a month or two. Freezer burn can develop, ruining the coffee.
What Causes Coffee To Spoil?
There are four main sources of concern when storing coffee. They are light, air, moisture and heat. Anyone of these or combination of these elements will cause coffee to spoil quickly.
The ultraviolet rays that come from the sun can do much more than give you a tan or sunburn. They cause a genetic mutation with coffee which attacks the chemicals that preserve flavor.
When this happens, the coffee will lose its quality in taste and aroma. This is why you should store any coffee beans or grounds in a dark place or a container that is not see-through.
Oxygen is as bad on your coffee as UV light. Air causes oxidization which will work to dry out the oils that occur naturally in the coffee. When this happens freshness and flavor suffer.
In other words, air pretty much turns your coffee beans or grounds into dull beans or grounds. This is why your storage container must be airtight and can release CO2 from the inside.
Moisture content in the air can be controlled with humidifiers which either add moisture or remove it.
Too much moisture can create mold growth on coffee beans or grounds.Not enough moisture can dry beans or grounds which destroys their quality.
An airtight coffee canister in normal comfortable humidity conditions will preserve the coffee for a longer period of time.
Warm temperatures may keep you cozy and happy but it does the opposite to the coffee beans or grounds you are trying to keep for use later. Heat just dries them out, stripping away flavor and taste.
This is why it is advisable to store coffee in an airtight coffee storage jar in a cool, dry location. The cool temperature locks in the freshness of the beans and keeps them happy.
What Happens After Coffee Goes Stale?
It’s not a pretty sight, to begin with. Stale coffee results from improper storage and when your grounds or beans reach this point, there is no mistaking it for something else.
Stale coffee tastes bitter. Stale coffee has a bad odor. Stale coffee will stink up your kitchen when brewing. To avoid this from happening you need to use a proper storage device.
