Double Decoction Kolsch

It's been a hot minute since I have had the chance to brew anything.  New job and life is keeping me down.  So I had originally planned on doing this batch a month or so back but just got around to this on Memorial Day.  I wanted to basically do the same batch of Kolsch I did the previous year, but do a decoction to see if I can pull some extra flavor out of the mash and also just to do one since I have never attempted anything like that before.  I do have to say that I love the way the decoction brews up.  I got super efficiency (82%) out of my grain and the finished wort dropped super clear after chilling.  Instead of using German Tradition this time around I went for Saaz, for a better hop profile.  I repitched the same yeast used last year from Gordon Biersch.  Surprised that the yeast actually kept for that long in the fridge.  Took it a few days for it to wake up, but now its rocking in the beer.

Update 6.10.2011: This one is a slow fermenter it seems.  After almost 2 weeks in primary it still has a nice thick krausen and still bubbling away, fermenting at 62 degrees.

Update 6.18.2011: Just recked over to a keg for lagering.  Beer finished around 1.010 which is nice, but being that my OG was kind of high the abv is on up there around 5.3%.  I was hoping to keep this beer around 4.4abv.  Ill check back in 4-6 weeks and see how this beer is looking.

Update 9.1.2011: Beer is drinking quite nice right now.  I plan on submitting 2 bottles of it to the Brewmasters Open, to see how it came out.
