It is a big debate if you can store ground coffee in a refrigerator. Though many people think it is gauche, there is nothing wrong with keeping ground coffee in a freezer.

In such a case, the freshness of the ground will depend on the packaging of the coffee. If the ground remains inside a vacuum-sealed pack, it will retain its freshness for up to two years.

On the other hand, ordinary packaging, even an airtight container, will not keep the flavor for more than six months. Most manufacturers sell their coffee grounds in aluminum and polyethylene packs.

These packaging materials ensure the highest ground protection from moisture, UV rays, air, and other impedances.

So, you can surely store them in a freezer up to the recommended duration without ruining the quality of the ground.
