I cant seem to figure it out. Tried using spring water, bottled water; extract brewing; well aireated/oxygenated wort; adherence to recomended pitching rates and fermentation temps, but still getting roughly 50%ADF when i should be getting 75. I did two seperate Identical batches using the Pilsner Urquell clone recipe discussed in Zymurgy (July/August 2011) Double decoction vs triple, OG 11.6P. After racking to secondary i'm getting like 5.9P. In past experience, after a 4 week lager, I'm lucky if I get anything lower than 5.5P. What gives?
