Havent brewed yet, just got all the ingredients together. Tweaking the basic Northern Brewer oatmeal stout kit by upping the oats to 1.5lbs, using 13 oz chocolate PB2 powder at 5 min and 8 oz molasses at flameout. Iwill be using 1 oz centennial 10.4 AA. I know I will have to skim the small amount of oil the PB2 will add. Anyone have any thoughts?
