Having brewed the recipe and now tried it side by side with my last can of the real thing, I can say I am waaaay off the mark. True, I didn't step mash, didn't do a decoction, and used 2308 instead of 2124 yeast. I also missed the 5 minute hop and put it in at flameout instead. But somehow I'm not sure those things would make the difference. There seems to be something in there that may not be achievable on the homebrew scale, at least with my setup. This was beer #3 in a series of beers, with the first, a helles, also sort of based on Bierstadt's recipe, on Labor Day.
My beer is actually a tasty beer, it's just no where near the real thing. The real thing has a penetrating, drying (but pleasant) bitterness, whereas the bitterness in mine, at least comparatively, is barely perceptible. Mine has 100% Hallertau mittlelfruh hops, per the recipe, but the real thing tastes way different. The aroma of mine is a sort of muted floral hops; theirs an almost skunky aroma that I associate with a lot of German lagers. Not a lot of malt flavor in either. Mine is a hair darker and more cloudy; theirs extremely pale and crystal clear. I also didn't treat my water, aside from using 3 gallons distilled water. Gelatin added to aid clarity, though this is not the clearest beer I've ever made.
In the end, no, I didn't follow the recipe exactly. In fact, I deviated substantially. But I guess I thought I'd be closer to the real thing, since the basics of the recipe remained intact: Weyermann pils, Hallertau hops, German lager yeast. Oh well, a fun experiment, and perhaps these German lagers -- helles, pilsner -- can be something to continue to strive for, my sort of "white whale."
