You could spin out the frames and keep the 'honey' just for feeding back to the bees.
I overwinter my bees on double brood (lots of room for stores going into winter) so when I do my first inspection, if there are stll too many frames of stores left in there I'll pull them out and replace with drawn comb or foundation giving more space for the queen to lay up. As I don't have the room to store all of these frames of stores in a freezer and I don't want to risk the waxmoth getting to them, I spin them out and keep this as 'bee feed'. It's kept solely for feeding bees (when making up nucs or feeding before winter) so that it doesn't matter that it might contain sugar syrup or thymol. It means I have to put in a bit of effort extracting the 'honey', but I find it much more convenient to store a tub of 'bee feed' and use make use of the empty frames back in the hive than to try and store brood frames full of stores
