The most recent grains used by us is Ireks Pils, and Weyermann Floor Malted Bo-Pils. We had good luck with Ireks. The Weyermann is good too.
Brewed 10 gallons of a Czech style Pils with the Weyermann, single grain. With Saaz hops. Diamond Lager yeast. Soft water.
It came out clean, crisp, and very light. My neighbor and brewing friend (Dave) said it is the perfect summer beer. But Dave detected a very minor hint of green apple. Very, very, slight. I think it is from the Saaz hops, because I have noticed this in our other beers brewed with Saaz.
