We made a Pilsner Urquell Clone on Dec 11, 2011 and used Saflager w- 34/70 yeast. It was fine out of Primary and Secondary. It had a nice flavor and was golden in color. We let it lager at 33 degrees till now. It is very clear but has darkened to an amber color and has a sorta cheap scotch aftertaste. I am surprized by the color change and the aftertaste. We use the standard Cornelius keg for Primary, Secondary and Lager Kegs. All transfers were done in a CO2 enviroment ( Target Keg Purged with CO2) and via a Black to Black transfer hose. Any ideas? BTW, the SRM at the transfer to the serving keg was about 3.5. It is now about 15.
