Is there any sort of crystallisation of the honey in any of the frames? It might be worth uncapping some to check (if you haven't already checked).
No but the little remaining on wet frames is of no consequence. The bees are straight up into the frames to clean them up
If some frames have some crystallised honey and others don't (or not so much), the extractor can get unbalanced as the runny stuff is flung out but the crystallised honey remains in the frame. I've had frames with crystallised honey in them blow out, mind you, that's in a radial extractor and they can blow out frames easily enough, particularly with newer comb. As to fermentation, are the frames all capped or is there still quite a bit of uncapped honey in them?
Put the supers on top of a couple of brood boxes or more if neecessary - put a lamp holder (an old table lamp will do) with a 25 watt bulb (no more - it will be too much heat) .. leave them to warm up ... 12 hours should do it. Check a couple of cells to see if it's runny enough to spin out... the crystallized honey is a lost cause except for feeding back to the bees. Uncap the frames and spin out what will come out. I would not worry too much about unbalanced frames just keep it steady and build up speed. Store the spun supers wet and give them back to the bees to clean up in spring. You might have to use the trick of putting the supers above a crown board with a small hole in it to get them to take it down. Hopefully not too much has crystallised.
You really can't feed frames back to the bees in winter - the time to do it was in the autumn when they were backfilling the brood nest (method above) - above a crownboard with a small hole in it - usually with an empty super or an eke below the crownboard. Best leave them now until early spring if they need feeding then or if it is honey filling the wonkly combs crush and strain and eat the honey !
In order to get them to put stores from above down into the brood box you have to convince the bees that it's a source of food they need to bring in .. if it's just a super on top of the brood box then that's where they think it should be - above the brood nest In order to get them to take the stores down you have to separate the stores from the body of the hive ie: above the crownboard with a small hole in it and then a space (either an empty super or a deep eke) then the box on top with the frames of honey you want taken down. Scratch the surface of the combs and when they are in storing mode they will take it down and re-store it above and around the brood nest where they need it. You have missed the boat now but if you are going to run brood and a half now through winter the odds are that they will treat the super on top of the brood box as stores and will just move up into it, so just leave them be and sort things out in Spring.
Do bees think?
I would eat it. Put it in jars and store in freezer. Take a jar out at a time and keep it in the fridge. Fermented honey is rather nice.If it smells fermented can it still be used? (a part from mead)
The fermentation (if any) should not be too bad I would have thought. What tends to happen with extraction where there is crystallised honey of differing degrees within frames, is that it the spinning will start out ok but then as the frames get unbalanced (as the runny honey is flung out) the extractor will start to dance (unless you have it bolted down or secured somehow). The vigour of the dance will depend on a few things like the rotation speed at the time, the size of the extractor and the degree of weight difference between the frames
. If each frame has basically the same amount of crystallised honey it will be ok of course. Give it a go with care. It will probably be ok.
