Mash 5 pounds 2-row, rolled barley and roasted barley in at 132 degrees. Protein rest 30 minutes. Starch conversion 2 hours at 153 degrees. Mashed out 15 minutes at 168 degrees. Sparged with 4 gallons 172 degree water. Add the 2 pounds dry ME and the 2 cups sugar. Bring to a boil. Add 1 1/2 ounces of hops. Boil 1 hour. Add 1/2 ounce of hops, turn off heat, and let stand for 15 minutes. Cool wort to 72 degrees, strain into fermenter, and pitch yeast.

Bottling: one to two days before bottling, sour two bottles of ale. To do this, pour two bottles of ale into a steril glass container. Cover with a clean cloth secured with string or rubber band. Put in the cupboard (or somewhere relatively dark and warm) and let stand one to two days. It should sour, but not mold. Add 2/3 cup corn sugar to the sour ale and boil for 10 minutes. Pour into bottling bucket. Add sour ale and bottle as usual.
