Tips for storing coffee in the freezer

The goal is to keep the moisture away from the beans. Wrap your beans using sealable freezer bags and plastic wrap. If you have other air-tight freezer containers-use them! Remember you want to do everything you can to keep the moisture away from your coffee.

Here are a couple of reasons why storing coffee in your freezer may be alright

Storing coffee in the freezer is not really o.k., but it can be done. If you have too much coffee or you are going out of the country then you can freeze your coffee. This is a one-time shot. Once you take your frozen coffee out of the freezer, it should never go back in. The frozen moisture will be absorbed into the beans as they thaw. The constant changes in temperature will ruin your coffee.

Here are a couple of reasons why storing coffee in your freezer is a bad idea
  • Coffee is porous. It is important that coffee is porous for flavored coffee. The beans absorb the coffee flavoring syrups and oils that are used to make the flavored coffee. However, coffee can also absorb other things like the smells of seafood or fruit. It can also absorb the moisture that your freezer produces. This moisture gets inside the beans and it begins to deteriorate.
  • When coffee is roasted, the beans release their oils and essences to give the coffee its distinct flavor (oils more predominant in darker roasts). The oils break down in the freezer and the flavor begins to deteriorate.
To Freeze or Not to Freeze

Some people store their coffee in the freezer thinking it is going to keep the coffee fresh. This is not true. The changes in temperture make the beans deteriorate. If you must freeze or want to know more–read on.

How Long Does Coffee Stay Fresh

Freshly roasted coffee (kept in the whole bean state) will start to go stale within 2 to 3 days. The coffee will lose it’s original flavor, body, and acidity by the 5th day. Once you grind your beans they will start to deteriorate within 2-3 hours. This is why it is important to grind the beans right before you use them. The reason the beans begin to go stale so quickly is because there is more bean surface exposed to the air.

The Misconceptions

There are popular misconceptions on the way roasted coffee should be stored and maintained. The enemies of roasted coffee are moisture, air, light, and heat. Storing your coffee away from them will keep it fresher longer. Therefore, an airtight container stored in a cool, dry, dark place is the best environment for your coffee. Remember that a cabinet near the oven is often to warm.
