31A - Alternative Grain

BJCP Style: 31A - Alternative Grain Beer 

Since having the Bierstadt and Finn's Manor collaboration from May I've been wanting to do a blue corn lager. This beer has just over 20% blue corn from the southwestern US. I'm hoping for some blue/purple/pink color in the final product but not expecting much in the way of flavor contribution. 


This will be the annual MURICA lager to be served on 7/4. Based on a Pre-Prohibition framework it contains as many American ingredients as I could acquire. Finding American yeast is tricky so I'm using Lallemand Diamond which is a German lager strain. 

Full recipe is on BrewersFriend but here's the TL;DR:
  • 2021-6-1 brew day
  • Malts: Rahr Premium Pils, Proximity Munich 10
  • Other Fermentable: SW grown Blue Corn Meal
  • Hop: Sterling
  • Yeast: Lallemand Diamond
  • OG: 13.4°P
2.3kg Blue Cornmeal

Added some mash water to help with dumping - don't want it all coming out in a block

Mash complete. Quite a bit of color from the blue corn!

Forgot to get an OG pic (it was 13.4°P; 75% efficiency), but here's a wort sample

2021-6-2 (+1): I did a 'quick chill' and left the window open in the brewery last night to chill the last bit. This morning it was around 18-19°C so I pitched the yeast. 

And away we go - already got some airlock bubbles about 4hrs later
