Berliner Weisse Fruitpop in Hell (Heavily Fruited Kettle Soured Berliner with Lactose)

[Steven Barrett]

Tossed in 5(!) lbs of mixed berries into my 2.5 gallon batch this afternoon. 2 hours later fruit purée is gushing out of the airlock. I don’t recall my last go at this recipe resulting in such an aggressive fermentation.
