People that don’t work in the coffee industry are often shocked when they learn about the lifespan of roasted coffee beans. It’s generally recommended that coffee beans be used within six weeks of being roasted.It’s still possible to drink coffee made from older beans, but it will have a negative impact on the taste.
Ideally, beans should be allowed to rest for a week after the roasting process. This is because the beans release large quantities of CO2 which can cause variable results when brewing. For this reason, our suggestion is that you purchase beans one to two weeks after their roast date. You should then be sure to use your beans in 4 to 5 weeks time.
When deciding the amount of coffee beans to purchase, you should think about how much coffee you typically consume over the course of a month. It’s also essential to properly store coffee beans if you want to maximize their freshness.
If you decide to buy ground coffee beans, you can expect to see their flavor decline at a faster rate as they deteriorate even more rapidly after they’re ground.
The Proper Way to Store Coffee
It’s essential to keep coffee beans in a container that’s completely airtight. A dark and moisture-free storage place like a a cupboard is also a must.
You should consider investing in either an Airscape or Friis container. These types of containers were specifically created for storing coffee beans. Proper storage is even more important if you buy coffee that’s already been ground.
What Causes Coffee Beans to Age?
Coffee beans will absorb moisture from the air whether they’ve been roasted or are still green. Both the flavors in coffee beans and the caffeine are water soluble. Any moisture exposure will lead to an overall decrease in quality.
UV rays from the sun can cause chemical compounds in coffee to break down. Because of this, it’s recommended to keep coffee beans in a dark location.
3. High Temperatures
Any temperatures that are higher than 25 degrees will increase how quickly coffee ages. Oils will rise to the surface more rapidly, and carbon dioxide will release at a faster pace. It’s best to store coffee beans at room temperature.
4. Air Exposure
Exposure to oxygen will lead to oxidization in coffee. Since coffee contains large quantities of oil, this can cause coffee to lose its flavor quickly.
Any of the factors listed above can cause your beans to deteriorate faster than intended. Even when coffee is properly stored, this process will naturally begin to occur six weeks after roasting.
This won’t be a major problem at first, but over time, the coffee beans will start to spoil.
Is It Possible to Store Coffee In The Refrigerator?
As mentioned above, it’s essential that you find the right way to store your coffee. The storage method you select will keep your beans fresh and will also have an impact on the way your coffee tastes.
It’s a common myth that keeping coffee beans in the refrigerator or even the freezer will prolong their lifespan. However, it could wind up having the opposite effect.
In fact, if you keep coffee in the fridge, you’ll likely end up regretting it.
After roasting, the moisture content of coffee beans decreases, which causes them to become hygroscopic. If you keep beans in your fridge, moisture will seep back into the beans, which will cause them to go stale quickly.
