Scarlet Fever (Beer)

Tuesday, January 14th, 2014

Let’s try something a little wild! This is based on Supplication by Russian River, but with significant alterations:

  • Skip the carafa to keep the color light
  • Use tart cherry concentrate. Easier to get and will turn it bright red!
  • Use lacto from Nancy’s yogurt for a full sour without the bret funk!
  • Plus the Nancy’s contains Streptococcus  – just not the pathogenic kind.

Brew Day Notes

Jamie and Phil shared in the fun and work.

Everything went pretty optimal. Hit the mash temps and OG perfectly. Collected 12 gallons of wort to ferment.

Update: 2014-02-06


After 2 weeks the beer was racked and moved downstairs to the 60F basement. Turns out there was a extra gallon. We’ll keep it around just in case we need to top everything off.

Meanwhile, a quart of starter was inoculated with the whey from a fresh container of Nancy’s honey yogurt. This was kept in a warm spot in the kitchen cabinet (80-100F) for 3 days. At this point, the starter was malty, but also very sour tasting. Each carboy received a cup of the starter and 12 ounces of tart cherry concentrate. Airlocks were then attached for the long, slow, anaerobic bacterial ferment.

I also added a bit of this starter to the spar bier – which seems to have stalled.
