DO NOT BOIL HONEY longer than 15 minutes!!
You WILL lose the delicate flavor when you boil longer.
I make lots of mead. I can taste the sweetness of the honey. I follow the rule above.
When boiling honey you need to skim the surface of wax and proteins. If you fail to do this you are heading for a hangover (IMO).
I've only ever added honey to beer once, but if I were to do it again I would brew my beer as usual and boil my honey seperately and add it to the beer at the end of both boils. I'm fairly certain that will help you retain the honey flavor you're looking for.
