`  :It could be an unusual floral source that is not commonly worked by the bees. I've seen seasons where the bees seem to work flowers that I've not seen them on normally. Do you have any university bee researchers or a government extension service for beekeeping that could do a pollen analysis of your honey?  Another possibility, is someone in the area open feeding. A friend of mine did some graduate research with Nestle's Quick (he had bought a salvage load - in this case strawberry) which is mostly sugar, with flavoring and dye. He open fed the mix in drums, and all the bees in the area made ``red honey.``  `
