General Information
Method: All Grain
Comments

Mashed 1 pound of grain on July 21, cooled to 120F and added a handful of dry grain.  Soured for 3 days and then boiled to kill of any critters before use in the main mash.

In total, 7.5 pounds of Belgian pils were used.

I more or less used whatever stuff I had on hand, so the recipe is a little funny.

7-24-2014: Brewed.

7-31-2014: Transfer to secondary.  Probably a short one to knock out the loose bits.

Procedure

Mash in with 2.7 gallons water at 162F (for 66F grains) to hit a mash temperature of 149F.  Mash for 1 hour, then mash out with 1.5 gallons of boiling water.  Drain the tun, then sparge with an additional 3 gallons of water at 168F.

Special Procedures

To sour:

Mash 1 pound of grain in 1.25qt of water at 153F for an hour.  Cool.  Once the mash reaches 120F add in some uncrushed grains.  Ferment at <120F for several days.

 The result should smell sweet, bready, and vaguely of sauerkraut.
