This was originally intended to be a Peanut Butter Chocolate Oatmeal Stout. I used 13.5 oz of PB2 Cocoa Peanut Butter powder at a late addition during cooldown. After primary ferment, racked to secondary and noticed I had only 4.25 gallons. Very thick sludge in bottom of primary, and the racked beer was BITTER with no PB or choc taste. Forgot to take a S.G. reading. Added molasses and topped to 5 gal. No ferment after 36 hrs, added packet of wine yeast. Fermentation began again in 12 hrs. The PB2 was definitely an experiment gone wrong. It will be interesting to see how my recovery efforts with the molasses turn out.

3 of 5

The molasses ended up giving a "what is that flavor" in the after taste, in a good way, and the bitterness is much reduced and the beer is now drinkable. FG of 1.016. I will use brewers best flavorings for my beers going forward.

Correction, FG was 1.013
