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 ūüôā ¬†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.

9/15/16 moved to keg to lager FG 1.016 pH 4.34
tasting really good.  nice dark malt character.  nice hop character.  clean lager.  clarity is bad but thats expected.  very promising.
10/9/16 gelatin added

i really like this beer. ¬†i don’t have a good example to compare it to but it is a nice beer. ¬†judges seemed to like it at the skirmish in the triad where it placed 2nd.
