1 1/2 Liters of Speise should be collected prior to hop additions, it will be used for bottling.
This recipe is based on a BYO magazine article and the book Brew Classic European Beers at Home.

I have also brewed this recipe a few times to good results. Control of the fermetnation temperature is the biggest piece of the puzzle. I agree with Getafix's temps. 63º is a good spot for this beer with that yeast. Make sure you get a good amount of O2 into solution and pitch a properly sized starter culture to get a good fermentation.

Its been almost 1 week since I brewed this, SG: 1.012 from 1.044.

My barfridge was occupied so this was fermented in a cold water bath. The fermentation started and continued a bit warmer than the ideal, 16*C (60.8*F) which rose to 18.5*C (65*F) where it stayed for a couple of days before rising to 21*C (70*F) - 22.4*C (72*F) outside the bath.

The wheat aroma and flavor really come through, it is more tart and dense than a typical Wheat beer. For now the wheatyness of it is most dominant, I don't detect banana, bubblegum. The spiceness is there but subtle. This brew still has a way to go, I like it so far. I'll be trying it again soon.
