Sweet whiskey & barrel on the nose, but the flavor is more straightforwardly porter, coffee, maple syrup. Lots of prickly carbonation. The real love-it / hate-it feature is the sweet finish, which really is an over-the-top, soda-syrupy maple sweetness. It lingers on the mind, if not in the throat: the finish is surprisingly clean, & not cloying. I'm still mixed on it.
