Thanks for all the great advice everyone! From the looks of it I'll be going with a rather tame brew, probably an american wheat with extra chamomile and probably some lavender. They seem like they would compliment eachother quite well. I'll more than likely make it a low gravity with intended residual sweetness from some honey as one of the primary fermentables. My other thought was to try something similar to Founder's Backwoods Bastard, an outstanding bourbon barrel aged ale, since it certainly knocks me out when I drink it. Unfortunately she doesn't like bourbon so I'm pretty much out of luck there! I'll just keep it simple and see where things go from there.
Also, I picked up a copy of The Compleat Meadmaker last night, I can't wait to start reading through it!
