I have used the Saflager yeast in a Classic American Pils, for which I usually use a liquid Bohemian (Czech) yeast strain. The dry yeast produced an alright beer, fermenting in the upper 40s, but I would not try it again. I found the finished beer lacking in the crisp, dry character I usually get with the Bohemian strain. Overall it was a decent, clean lager, but other brewers I know have had fruity off flavors from the same strain (likely at higher fermentation temps), and my impression was that it took slightly longer to finish, needed to lager for a longer time before clearing, and was not nearly as clean as the beer produced using the liquid strain. I have since reproduced the beer using the liquid Budvar strain, and again had a superior beer with a cleaner finish.
