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.
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.
