Czech Pale Lager eBIAB 1

My first lager on the new eBIAB system.  We’ll see how it goes.  Another beer that I think will be one of my NHC 2016 entries.  Great “Style Profile” write-up by Gordon Strong May-June 2015 BYO on this style was my inspiration and where I got this recipe:

One big variance is my Homebrew Shop didn’t have 2633 so I settled on 2308 Munich Lager which I’ve used numerous times before and I really like it for more balanced lagers (no super malty, not super hoppy) and although this beer is hoppy it should have a soft edge which I’m hoping this yeast will provide.

10/24/15 made 1.2L / 120g DME starter w/ 1/4 tsp of yeast nutrient
10/26/15 normal brewday.  cooled to 45F pitched at 12:30pm @ 49F and set to raise to 50F over 24 hours and hold for 2 weeks than raise 5F a day for two days to 60F and hold till ready. (~3 weeks total)
10/27/15 slow steady bubbling
10/28/15 nice 1″ kreusen and soild bubbling
10/29/15 ditto
10/31/15 kreusen is dropping and bubbling is slowing but still steady
11/1/15 no kreusen ~2 sec apart
11/5/15 ~2sec still
11/7/15 no bubbling
11/10/15 raised to 60F for diacetyl rest over 2 days and bubbling started back up very slow
11/16/15 racked to keg and put in lagering fridge @ 35F  FG 1.016
really nice.  very clear in carboy.  nice malth w/ a little diacetyl -> very low.  a good amount of sulfur.  solid bitterness w/ nice classic saaz hop flavor and aroma.  very promising!  there were 4.5 gallons in fermenter so about 4 gallons into lagering keg.
12/7/15 racked to keg and put @ 30psi @ 40F.  will lower tomorrow to 14 psi.
12/10/15 carb is already good.  beer has good clarity with just a little haze.

vs. pilsner urquell (side by side tasting)

aroma: PU has more saaz hop aroma as well as a bit more malty sweetness in the aroma a little diacetyl.  close but PU has a bit more hop and malt character

flavor: similar to aroma.  PU has a bit more saaz flavor and malty sweetness.  mine has a hair more mineral edge – PU is very soft.  PU is a hair more bitter.

appearance: PU is clearer but close in color and head

mouthfeel: mine is a bit thinner but it is also a smaller beer so i think that is OK

overall: in the right vein but up saaz 50% in late additions, up IBUs by 5 and work on improving the malt character.
