I brewed a slight variation of this last year for an Oktoberfest block party. I had only 5 lbs of Pils and 5 lbs of Vienna, so I added a lb of Victory to make up the difference. Additionally, I had no Hallertau so I substituted Willamette. This was also he first truly public exposure of my beer, other than periodic samplings by guests at my house. My keg was empty long before the the Triple C, one of he local Charlotte micro-brewery. Lots of great comments from the crowd.
I now have a new batch in the fermenter. I hit the original gravity at 1.060 and the wort was bubbling vigorously in less than a day. But after two weeks in primary (ambient temperature at about 65), the gravity is only down to 1.022 - 1.024. I have racked it to secondary, but I guess I'm a little worried I have a stuck fermentation. I'll test it again in another week. Perhaps this is just an exercise in patience.
