Fruit Beer – All Grain GONE


General Info

Boiled the decoction for 30 minutes. Batch sparged and collected about 13.5 gallons. Efficiency was ~8% higher than expected (especially for a wheat-based brew). Boiled for 1.25 hours to reduce to 11.5 gallons and added bittering hops. Boiled for an hour more and collected 10 gallons for fermentation.

Six hours after pitching the yeast, fermentation is definitely evident thanks to a very large (about 3/4 of a gallon of 1.030 wort) yeast starter. Pitched just 12 hours after its fermentation peaked. Did not decant.

Split batch and racked to secondary containing five pounds of blackberries (frozen then thawed). Additional fermentation was evident a few hours later (August 29, 2009).
