I am almost ready to move an oatmeal raisin stout into the secondary, following a basic recipe kit but adding ingredients I found for another recipe. Right now I have, as suggested, the raisins, cinnamon sticks, and vanilla beans sitting in bourbon. However, the recipe states beer should be "racked onto" the ingredients. Im new to this and confused at what its saying. Am I just throwing this into the secondary or am I washing the beer over this mixture?
I would like to think that I should let these sit in the secondary to bring out the flavor, but im just not sure on the lingo.
