Sweet and dessert-like opening, smooth caramel. Thinner in feel than you'd think given that description, and I thought the saltiness came across as unpleasantly briny. The salt makes the turn from sweet to roasty less appealing.
What you'd expect from Southern Tier, a clear, candy-like expression of salted caramel, maybe not as salty as I'd expect, but also accompanied by strong, alcoholic, and maybe an over-roasted (read: harsh) finish. Others said it was very smooth, maybe something was up with my palate today, but I've felt the same about other Blackwater stouts.
