Sep 17, 2013 FAQ: To Freeze or not to Freeze Coffee? This question comes up frequently, even today as a matter of fact, so we thought we'd share our findings. Surprisingly, there is no substantial difference in the taste of fresh beans from those that have been frozen (over a short period of time, say a couple months and stored properly). Some recommendations though: valve-sealed bags produce the best tasting cups of both whole bean & pre-ground coffee. do not refrigerate as beans are kept in a constant damp state and are exposed to odours unlike the more controlled and cooler environment of the freezer. if you choose to freeze, freeze in small amounts (1 week supply) in a well sealed container or valve bag. Once removed from the freezer, allow beans to come to room temperature before grinding and do not refreeze. The conclusion for ideal coffee: If your fortunate enough to have a roaster in your area, buy beans fresh, in small batches (1 week supply), store them whole or freshly ground at room temperature in a sealed valve-bag for the most delicious results.
