I brewed this with only a few changes: didn't adjust water (NYC tap always seems to work OK for me), primed with sugar instead of krausening.
This was my first brew with my new wine fridge fermentation chamber and I was able to keep it nice and cool even during a HOT New York summer. The results were incredible. A clean, balanced, easy drinking Alt. I've only had one commercial sample to compare to, Southampton Dusseldorf Alt. And while I'm not surprised that my version isn't quite up to snuff, this is without a doubt the best homebrew I've produced.
I should also say that since taking up homebrewing I have developed a newfound appreciation for German styles. Its easy to cover-up flaws with massive amounts of hops, spices, etc. But it's deceptively hard to make clean, crisp, delicious beers. Definitely gonna try a bock this winter (my first lager!).
