Apparently Atlantic Sweeteners out of Charlotte still sells HFCS 55 to beekeepers. They do not however sell sugar syrup due to FDA regulations.
55 is going for 23.5 cents per pound or about $150/barrel.
Apparently Dutch Gold honey is using dry sugar to feed their bees. Can bees draw comb from dry sugar
Corn syrup is still an option if you prefer that kind of thing.
