How to properly store coffee beans so that they remain aromatic for a long time: useful tips
Coffee is a drink without which it is very difficult to imagine the morning of every second person. It is a very tasty and invigorating drink that can be prepared and served in many different ways. But it is very important to remember that beans and ground coffee must be properly stored to keep the drink flavorful and tasty.
How long can coffee be stored?
Max Gualtieri, a longtime barista, coffee roaster, and founder of Joules and Watts Coffee, says that there are a number of factors that determine how long coffee stays fresh.
"The type of coffee, mainly the variety and degree of roasting, can affect the longevity of coffee," the expert says.
It is very important to know that coffee freshness is affected by moisture, heat, and oxygen.
Gualtieri says that the best thing to do is to buy whole beans, so coffee stays fresh longer.
"Whole beans have a smaller total surface area than ground coffee, which means that whole beans are less exposed to oxygen, which slows down the oxidation process, resulting in a stale coffee taste," the barista says.
Most roasting experts recommend brewing whole coffee beans within the first two weeks after roasting, but with proper storage, they can last up to two months.
"Ground coffee starts to lose its spice as soon as you grind it," says Gaultieri.
To keep your coffee as fresh as possible, brew it as soon as possible after grinding the beans. Description:
Once coffee is ground, it loses its flavor about sixteen times faster than whole bean coffee. If the coffee is pre-ground, it should last about a week before it loses its flavor.
Store coffee in its original packaging.
It is best to store coffee in its original packaging
Gualtieri says it's important to store the beans in the right packaging to help with degassing and oxidation, which are the two main processes that change the flavor of coffee.
"During degassing, the carbon dioxide that is formed in the beans during the roasting process is released from the beans. When carbon dioxide is released from the beans, it carries with it compounds that determine the flavor and aroma. After the carbon dioxide is released, it is replaced by oxygen, which seeps into the porous beans, which also leads to a duller flavor," explains Gualtieri.
It's worth noting that, according to the expert, exposure to air further increases oxidation, which makes the choice of storage location very important.
By preventing contact with air, you can slow down this process.
The best way to store coffee
Coffee is best stored in its original packaging, which has a one-way valve that allows carbon dioxide to escape and prevents oxygen from entering.
"If the original packaging does not have a degassing valve or you prefer to pour the beans into another container, be sure to use an opaque, airtight container," advises the barista.

How to store ground coffee?
"It is best to grind coffee just before brewing. Grinding coffee exposes all the aromatic and flavor compounds in the beans to the air. This accelerates the processes that cause coffee to spoil, so to prevent coffee from becoming stale faster, brew it immediately after grinding," the expert summarized.
