Did you feed the colonies sugar syrup after you put on your surplus honey supers? If you did it is probable that there is syrup stored in them. If you had a good nectar flow in your area the stores will probably be a mix of nectar honey and sugar syrup. You can use this for your own use, but I would not sell any because you would be passing syrup off as honey. It is probably best to use what you have as food stores for the winter.
