Therefore, once you open your vacuum-packed coffee, you want to make sure you place it in a container with a good seal. An airtight container keeps moisture and air away. When the flow of air within the coffee grounds is reduced, the coffee retains its taste for longer.

If you have purchased a significantly large amount of coffee and you do not intend to consume it all at once, here is a tip. Divide the coffee into two. Store most of it in a large container and some coffee in a smaller container for your frequent use.

This means that most of the coffee will be stored away from air, therefore, maintaining a longer life span.

The best material for the airtight container is Glass, Stainless Steel, or Ceramic. The container should be placed away from light. This, therefore, means the best container to use is a ceramic container.

When you need a pack from the frozen coffee, get the amount you will need and place the rest back to the freezer.

With these two methods of storing coffee, the life of your vacuumed coffee is expanded; airtight containers increase the expiry period by 2-3 weeks while freezing increases it by up to 1-2 years.
