Bavarian Hefe in general, but there's not a whole lot of changes that can be made anyways in this style. The grain bill is by German Law >50% Wheat malt, and backfilled by Pilsner malt.
They are traditionally hopped to around 13 IBUs using traditional German Noble hops, with no flavor or aroma hops. The single small charge of Hallertaur (Mittelfruh if you can get it, but any variant, including its' American daughters like Sterling, Mt. Hood, Libert, or Crystal, will work beautifully too) will add pleasant light, clean & spicy bitterness only.
You asked for Honey malt, so I simply added a half pound to accomodate that request, and since you need to mash it, added a lb of Wheat malt to convert it and not go below 50% wheat malt requirement of German Hefe's in general.
Yeast wise, 3068 from Wyeast is sourced from Weinstephan, but its flavor profile gives by far the best hefeweizens I've ever tasted. Maybe if you really want to go for the true match,you could try to culture from a few bottles of Franziskaner. That's a lot of work, but it would probably be the one thing that could change the flavor profile the most.
Anybody else have any thoughts on this?
Wow thanks so much for the detailed response. I love weihenstephaner so I will be fine with that yeast. I only requested a franzy clone because I know the bride and groom both like that beer a lot. But as long as its a well made wheat i am sure they will be fine with it.
Last question, the beer needs to be ready for sept 19th. If it were you brewing, when would you do it? I obviously want it to be ready by then, but also want it as fresh as possible.
