Hey fellow brewers, I brew 2 gal. batches in the old Mr. Beer LBK's I am planning on brewing the Abbey Dubell.I've got all the goodies.LME,Yeast,Adjuncts etc.,but wandered what dark candi-sugar "Rocks" would add to the recipe.In your opinions,will it add anything to the recipe.If so,how much should i use for a 2.13 gal batch,and when should I add it at boil,flameout or when.TIA for your guidance.
