Czech Dark Lager eBIAB 1

Beer 6 of 12 for my Skirmish in the Triad run of beers.  I’m now beginning to question my sanity 🙂  Half way there and I feel like every night I’m doing something beer related.  Or at least that’s what my wife keeps telling me!  For NHC this year I have 7 beers planned and i’ll send the best of those and i’m brewing all of those for the skirmish so i can get a dry run in and get feedback and make some adjustments.  My first Best of Show was with a Czech Pale Lager so I thought I’d give it’s darker cousin a try.  It’s a new style to the BJCP 2015 guidelines and a bit hard to dig up any example recipes.  The best I found were in Gordon Strong’s Modern Homebrew Recipes.  There are two and after going through the guidelines I picked the one that is similar to U Flek and then messed with it a bit.
