Well, I could not leave well enough alone.... I made this yesterday with 1 lb extra light DME, 6 lbs Munich Wheat DME, .5 lb Munich Briess 6-row, .5 oz Hallertau and .5 oz Hersbrucker hops at 60 minutes. Pitched a starter with Weihenstephan Weizen 3068. OG=1.060, SRM=12 and only 10 IBU. This is at the upper end of the Weizen style, but not quite a Weizenbock.
My only issue was with getting all of the DME dissolved into only 1.5 gallons of wort. I have a 5.5 gal. brewpot and experienced my first boilover when I turned away for only a moment to prep the sink for the cold immersion.
That said, it all cleared up very nicely; the smaller wort amount allowed me to get the temp down in less than 10 min, and with the starter the thing took off in about four hours. I have it in a swamp bucket with the water at 70 degrees.
I think it is going to turn out very nice!
