Weizenbock – All Grain GONE

Statistics

General Info

May do well as a fruit beer with raspberries or blackberries.

This is the first time I'm using the 16 gallon plastic fermenter. It will be nice to have a single, ten gallon batch fermenting in one primary. Naturally, the beer will be separated at secondary, which will give me a great opportunity to let one secondary go "as is" and possibly add some fruit to the other. I'm thinking cherries or blackberries for a brew with the level of sweetness and Special B characteristics this one has.

I intentionally chose the American Hefeweizen yeast strain to downplay the clove phenols and banana esters that are normally associated with the German varieties. I'm going for a more "clean" characteristic (which is not very Weizenbockish) that will let the malt shine through.

Comments

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.
