Bohemian Pilsner 2

New Year, New Brew!  It’s the last of my NHC beers.  I’m getting a bit nervous since I’m not sure I have 3-4 really solid beers.  Hopefully this one will turn out well!  I did my normal research – Brewing Classic Styles, old NHC winners and reread the Bohemian Pilsner section in the Classic Style series.  In the end I remembered an old Annie Johnson interview on The Brewing Network where she talked about winning a Pilsner Urquell clone competition so I thought that would be a good start.  Her recipe (scroll down to “this budvar’s for you” ) is a decoction so I basically took her recipe but added some Munich Dark to get a bit of a decoction character and to darken it up to get it from straw to gold (hopefully).  Since I’m repitching German Lager (White Labs 830) rather than a Czech strain I added a bit of Carapils to round it out.  I wanted to use all Czech Saaz but my homebrew shop only had 4 oz so I used Warrior for bittering.  This is my last brew on the old propane setup before starting on my new Electric BIAB so it was a little sad.  I’m sure I’ll use the old rig again but probably not nearly as often.  Brew day was pretty standard.  I actually hit all my numbers which is pretty much unheard of.  No adjustments necessary.  Maybe that’s bad 🙂
