I was brewing 5 gallons of oatmeal stout (extract kit) last weekend when a neighbour decided he wanted to ?help?. The recipe calls for 3lbs of dark dry DME, but my helper dumped in a pound of amber from a brown ale kit. I measured out 2 lbs of the dark dry and added it, unsure if it could be salvaged at that point. Everything else went according to plan. Does this batch have a chance?
