This probably illustrates my lack of knowledge about mashing in general, but I'm going to brew a barleywine with first runnings, and a stout with the second runnings. I'm going to be adding 1 pound each of Crystal, black, and chocolate malts, and possibly a couple pounds of wheat malt after I have drawn off the wort for the barleywine.
I'm planning on adding the additional water, add the grain, stir, but then I'm lost. On Denny's page describing batch sparging, he says immediately draw off again, but this is without additional grain, for a single beer. How do I do this for two separate beers?
