I'm brewing another Pilsner this weekend, a Bohemian. I saw the correspondence with someone from Victory earlier in this thread and they stated a 13ºP (1.053) starting gravity and the ABV is 5.3 so you would think the FG would be around 1.0125. I went to my local bottle shop and picked up a few bottles of Prima Pils, degassed one and took a gravity reading...it was 1.006! That seems very low and would imply the ABV is 6.2% assuming a starting gravity of 1.053.
When doing research for brewing a Tripel or Golden Strong, I did the same thing with Golden Monkey. In BLAM, they list the OG at 1.085 which would give a FG of 1.0125 for a 9.5% ABV beer. When I tested the real FG, guess what it was? Yup, 1.006.
Take this info for what it's worth. I'm sticking with the 13ºP OG for now. Maybe through their decoction regimen, they have found over time how to keep a full body with low FG. That would save them on grain costs.
