Plum Permeation is the first in our series of oak fermented sour ales, refermented on fruit. The grain bill was mostly barley with a touch of wheat, and aged hops were used in the boil. The wort went directly from the kettle to oak for fermentation with saccharomyces, brettanomyces, lactobacillus, and pediococcus, and was allowed to age until the right balance of sourness and funk was reached. Once that was achieved, plums were added at a ratio of over one pound per gallon. The resulting ale is pleasantly tart with moderate plum, hints of herbs and oak, with a touch of barnyard funk.
