Maashed in my 10 gallon cooler.

21 lbs grain, 6.5 gallons water @ 153F for 70 minutes.  Sparged with 10 gallons of water at about 170F.  Took about 40 minutes to fly sparge.

Pre-boil gravity = 1.050

Brewhouse efficiency calculated at 80%. 

Use hop bags for hops additions.

Vigorous boil for 70 minutes.

I forgot to add yeast nutrient, and did not add whirl flock until flame out.  Seemed to work anyway.

Used plate chiller to cool wort to 68F, and ran it into a pair of carboys to let the cold break settle out.  I will transfer to fermentor after 6 hours of settling.
