Hey Jen! I'm gonna go out on a limb here and say no. Bees REMOVE water from nectar to make honey. But then, they do need water to survive so I guess if they didn't have any water they would die and therefore not be able to make honey, so yes, they need water to make honey.
Just messin around. I don't think they do, as in they don't use water as an additive to make honey. Ted
