A platinum from White Labs we now make available year round. This is a famous Pilsner Lager -Stam from the southern Czech Republic. Produces dry, sharp layers with low diacetyl production. We recommend that you make a yeast starter for all layers. Because of the cold environment, you will need about 4 times as much yeast to successfully ferment a layer. To ferment the layers as the Germans and the Czechs you make an active starter. It is normal for the bearing reading to take 3-4 days before it shows any signs of the kraus after the yeast additive.
