Oooh, timely. My next lager yeast will be 2278 and I already have a couple of beers planned for it. I can't see what separates this beer from other gold, German lagers but I like it. I would probably dial it down just a smidge so it wasn't 6% but I could easily see this working. The only Google results I found for Zeltbier is from Victory in PA and the description sounds like a Marzen/Festbier.
Exactly. this was a recipe I found in a BYO article; This is a brewpub only release from them; I had it a couple years back when I was in the Downingtown area, and stopped in, and was blown away by that particular beer. By style, its a festbier; they also distribute a beer called "Festbier", but its a super malty Marzen- while good, its on the heavy end of the marzen style; full bodied and super malty; best I can describe as a dry, just short of a single bock. This beer, you could have a 2nd liter before you realize it.
