Colorado Vienna Lager (previous batches)

This is the archive page for the Colorado Vienna Lager.

CoVienna.jpgLate 2021 / Early 2022, I noticed that one of my favorite local homebrew shops was adding more and more malts from local Root Shoot Malting

Some of their are really unique, and I really liked the character / color that the malts add to my homebrews.

I started using them more and more ... especially their Vienna Malt and their Dark Munich Malt.

My Colorado Strong IPA used all Root Shoot malts, and shortly after brewing that beer, I decided to try a Vienna lager featuring their Vienna Malt and their Dark Munich Malt.

Recipe Notes
Make 1.4 liter (6 cups) yeast starter a day before brew day.
Brewing salts in the mash water. This should bring Denver water profile (as defined by BeerSmith) to "Balanced Amber"
Acid addition to bring calculated pH around 5.4
Brew as directed from recipe.
Cool wort to as close to 50 degrees as possible.
Ferment in 50's for about 5 days, let rise to high 60's for another week.
Keg carbonate.
After the keg is chilled, add geletin to keg.

Brew day today. Started around 4:30. Yeast pitched at 9. OG 1.051. Low, even though my pre-boil gravity was right on. I think maybe I need to reduce my expected mash / brew house efficiency. Maybe reduce my boil off rate again. 
02/15/2022 esheppy
Took awhile to get going, but bubbling strong now. Tilt says 1.040 at 52 degrees. Control set at 52 as well.
02/16/2022 esheppy
Still bubbling strong. Tilt says 1.025 at 52 degrees. Raised the controller to 53. Batch seems to be on track. 
02/17/2022 esheppy
Forgot to switch ice bottles before going to bed last night. Temp was up to 60 this morning. Set the controller to 57 so I'm not dropping too much. Tilt has gravity of 1.020. 
02/18/2022 esheppy
Still bubbling. Tilt says 1.007 at 58F. Took a little sample. Still very cloudy, but I love the color. Certainly lighter than what I generally think of Vienna lagers. The flavor is very nice too. Certainly more malt forward than hoppy. Very balanced, though, and certainly not sweet. Love the cracker / bread of the Vienna and Munich malts. This is going to be a great beer. 
02/20/2022 esheppy
Tilt says 1.003 at 61. Unplugged the pump. Might keg this week. 
02/22/2022 esheppy
Tilt says 1.004 at 64. Took a little sample. Still not looking clear, but certainly not as cloudy as before. Color is a light copper. Maybe a little hops coming through but mostly a great cracker / toast malt flavor and aroma. Nicely balanced. Not really sweet at all. Going to be a great beer. 
02/27/2022 esheppy
Kegged today. Couldn't get flow going with closed transfer, so I opened it up. 1.011 fg. Color a bit darker than I thought, but which really puts it more to-style. Nice Vienna lager flavor. I'm gonna really like this beer. The keg is chilling. Really full. 
03/01/2022 esheppy
Fat Tuesday. Had some big pours to add some headspace. Then I added the gelatin and pressurized. Giving up beer for Lent so I'll try on Sunday. ?? 
03/06/2022 esheppy
On Boo Berry brew day, had a pour from the tap. Carbonation seems pretty good. Clarity not great, but that is probably pulling bottom sediment. Great flavor. A little more malt sweetness than I remember from kegging day. Nice amber lager. 
03/11/2022 esheppy
Everything pretty much perfect now. Carbonation and clarity right where I want them. Yummy flavor. Beautiful color. 
03/13/2022 esheppy
WTF. Somehow my tap wasn't completely attached overnight, causing a leak. This keg is done. This doesn't make me happy. Dammit. ?? Need to aggressively brew.
