I grind straight out of the freezer. I use food saver vacuum bags when I buy large quantities. I also freeze 12 and 16 oz bags from roasters. I stick a piece of tape over the valve and in they go. I think the major factor is avoiding the freeze, thaw, re-freeze cycle.

Been freezing in ball jars for years, no problem. I single dose.

Thank you all
I freeze my beans (purchased) in their 12 or 16 oz foil bags stuffed inside gallon ziplock bags.
Take out of freezer, scoopnout for my one or two shots and immediately replace the coffee in my freezer. Not able to comment on grind being different for these freezer dwellers. I grind by taste and flow. Is the shot a tad too bitter? Did the shot run too fast? Slow?

My impression is that you are dealing with two different SOPs, done for two different reasons. If you like to roast larger batches, storing in the freezer (valve bag valves taped shut) and letting them defrosts in one week portions makes sense. On the other hand, if you think the coffee is great, say, five days post roast, and not so great any other time, it makes sense to age it five days, then single portion grind it straight out of the freezer until its done.

I would suppose the idea is it's increasing degradation of the exposed beans that aren't ground but I've not had an issue with smaller containers holding only a few shots worth.

So if the coffee is in a jar and the jar is well sealed, having that air space in the jar is no problem? Same goes for being in a bag, for that matter?

I store them in the fridge, but before grinding i let them outside to get room temperature and then i grind them

I freeze in small 8 oz Mason jars 5-7 days post roast. Usually different varieties in marked jars filled to the rim. I pull out a jar the day before planned use, and don't break the seal until they fully come up to room temperature. This avoids condensation on the beans.

I don't see a significant problem pulling a frozen single dose from a larger quantity in the freezer for immediate use, especially if the bag doesn't come out. As mentioned the condensation on the frozen single dose just before grinding should benefit static reduction.

With either method, as long as beans don't gather condensation and refreeze or sit wet for later use, I think it should be fine.
