Tired of trying to chase down these beers so am thinking of taking a crack at a clone. I am planning to start with the BYO recipe for Founders Breakfast Stout, boost the o.g. to hit the stated 10% abv of KBS/CBS, and dose with bourbon and oak until the flavor is right - that should get me KBS. What I'm unsure of is the maple addition to turn it into CBS. I think I want to use grade b syrup for more flavor / less fermentables, but am unsure as to how much I should be adding and when. End of boil? Primary? Secondary?
Input is appreciated!
