General Information
Method: All Grain
Comments

Used yeast cake from previous "Random Brown"

Mashing slightly lower to drive down the final gravity might be a worthwhile experiment, but it is probably as good as it needs to be.

Another experiment would be to increase the roast barley and decrease the chocolate to try to lighten the head coloring.

Procedure

Preheat the tun with 5.6 gallons of water, 157F for 66F grains.  Add in the 18lbs of base malt.  Once incorporated, add in the cooked oats (see Special Procedures).  Ensure the mash is at 154F and conduct the rest for 60 minutes.  With a very thin draw, do a decoction mash-out; 3 gallons boiled and returned to get to 170F.  Sparge with an additional 3 gallons of water at 170F.  Wait 10 minutes between stirring and drawing to prevent a stuck sparge.

Special Procedures

-Cook the oats as with 1.25 qt/lb boiling water.  Stir and let sit for 5 minutes.  Add to the mash after the rest of the grains

-Very slow sparge - be prepared for a long draw.
