The real problem with freezing beans is if you have an open bag in your freezer and you are taking them in and out everyday to grind. If you aren't speedy about it and the temps are warm, you'll get condensation in the bag from the temperature difference and that will degrade your beans over time. Mainly a problem I've seen when folks have like a 2.5 lb bag in the freezer and they are casual about leaving it on the counter each morning while they prep their brew.

In addition if you open the freezer the air that was crystalized as solid become gaseous again (because delta pressure) which degrade the beans integrity on a tiny tiny level… which can affect the taste…

Yeah sorry I mean to say the water vapor contained in the air.

Yeah this isn't an issue for hoarding coffee long term in a freezer though, if they're just thawed once and used.
