Storing your coffee properly will keep it fresh for longer.
The best way to store coffee beans and ground coffee is to keep them away from air, moisture, heat, and light. Ideally, you'd store your coffee in an airtight container inside a cool, dark cupboard. The container should be as small as possible so that the amount of air it comes into contact with is limited.
Please just do not put your coffee in the fridge or freezer. That's not where it belongs.
