This is another go at the two week lagering method. This time however, I have created the recipe for my system and made some minor tweaks such as adding a bit more carapils and mashing a a little higher for more mouth feel in the body. One of the landmarks of a good Czech pils is its nice malty body. I have not been able to source any Saaz at all locally so Sterling, which is a gorgeous and under utilized hop in itself, will make a good substitution. Added some flameout hops also, hoping to catch just a bit more hop aroma.

Add fining – 1tsp gelatin to cup of boiling water and stir to dissolve and let settle 1 day
Rack to keg and let carbonate – depending on your preferred method to carbonate it will be ready to drink but I found on the last batch at least a week was optimal for conditioning, so were looking at around 3 weeks from “grain to glass” for best results.
