11 days from brew to mouth? Is that not cutting it a little on the fine side for any brew, let alone a stout?
Sure you'd want to be leaving it fermenting for at least 2 weeks and the same again in the bottle, even longer for a stout.
But even if you were determined to go ahead with it, as TheBeerNut has already said, most online places have a next day delivery if you order early in the day.
