Tried it several times. If you do a "Quick Search" for freezer, you will find a number of threads.
I only freeze beans if I am going to be away for a few weeks without the opportunity to roast.
Only freeze in small quantities. If you want to store 500g for example, break into 5x 100g lots.
What I find is some beans seem to freeze better than others,flavours are not quite as good after freezing and, once thawed, beans will tend to deteriorate more quickly than regular storage.
Also, freezing will stall the de-gassing process so if you like to rest beans before consumption, rest them a little before freezing.
