dmashl, I do that with hops all the time - brew with what I've got, that I think will work well in that recipe, rather than buying hops specifically for a recipe. I do it with grains, sometimes, too. For example, I almost always buy Munich in bulk, so will seldom buy Vienna if a recipe calls for it, I'll sub Munich. I also buy 20L and 60L crystal in bulk, so will almost never buy 40L or 30L or 10L, but rather sub. Never say never, but I do that a lot.
