Don't worry about your honey in the freezer. 10 years or 100. It should all be good. No different than honey from 2000 year old pyramids. I do leave frames in the freezer from late summer to early spring.
Okay, when you decide it's time to feed the honey to the bees, how long do you let it sit out before adding it to the hives? I'm pretty sure it would be a bonehead move to stick frozen combs in there with them!
