I've got a honey kolsch lagering now. This my first try at using honey in a beer and I used my own wild honey that was added to the boil at 10 minutes. Primary is complete, I racked over into a carboy and I'm into the 3rd week of lagering and I'm very surprised at how strong the floral honey note has remained in this beer. I was really expecting it to be a bit dry because of the honey, but it seems to be maturing nicely. It has a lot of body, nice and malty with some interesting floral notes.
As a bee keeper, I can assure you honey is not sterile. It is somewhat antiseptic because of the complex enzymes it contains. Raw honey when first slung out of the comb is loaded with bee parts, pollen, and all sorts of micro organisms. Big Honey, (think sue bee) pasteurizes, filters and blends different honeys, and I've heard other syrups, to get a consistent product at the grocery store. All I do is run whatever comes out of the hive through some fine mesh filters to get rid of the hive "trash". Nor do I run my hives around trying to catch different blooms for different honey characteristics. Whatever nectar the bees think have the highest sugar content is what they put in the hives. Most of the time it's very, very good. I think they know what they are doing.
