Czech Pale Lager eBIAB 2

My third NHC beer.  Very similar to my first attempt at this beer but I went with all Weyermann malts this time and upped the Saaz by 50% in the 10 min and whirlpool additions.  I also switched to the pilsner urquell strain.

not sure how i feel about this beer.  it is really good and hits all the style markers but there is a whisper of diacetyl which i’m not a fan of.  i think it can do well in competition but not sure it is my thing.
NHC 2016 results:
It scored a 32 and its marked as 2nd in it’s flight but did not go to mini-BOS.  the judge complaints are harshness from oversparging and overly bitter.  i didn’t get either of these from this beer and they didn’t mention what i was noticing (diacetyl) so not sure what to make of it.  kinda hard to oversparge BIAB 🙂  I guess I could tune down the bitterness but i really think it is spot on if not a hair low.  I think these comments are going to be ignored.  Scoresheets:

Colonial Cup results:
We have a winner!  Not only a winner in category but BOS!  Kinda surprised since I wasn’t sure what to make of this beer but when I drink it next to a pilsner urquell it hits all the czech pils notes – a little sweetness, a hint of diacetyl and a nice solid but pleasant saaz character.  This recipe came from a BOS recipe that gordon strong gave out so I’m thinking it’s a pretty good recipe 🙂  Scoresheets:
