General Information
Method: All Grain

3/15/15 - Pitched at 9p.  Aerated for 10 minutes, until a thin froth covered the entire surface.

3/16/15 - Evidence of positive pressure at 8 hours.  Krausen had formed by 20 hours.  Indicated 62F with a room temperature of 59F.  Unseasonable warm weather has prevented the furnace from running and the basement is cooling significantly.

3/17/15 - Still happily fermenting along.  Good, stable krausen and rolling ferment.  Indicated 62F in a 60F room.

3/18/15 - Still fermenting nicely, krausen slightly receded.  I draped a dish towel over the carboy in an effort to slightly raise the temperature.  Indicated 62F, room 60F.

3/22/15 - Transferred to secondary.  Still some activity as it finishes.

5/19/15 - Bottled with 5oz corn sugar.  Yielded 23x22oz and 6x12oz.
