Real toasty marshmallow on the nose, nice and sweet but thin

Bomber from Bine & Vine. Pours dark brn/blk with a very large, foamy, very dark tan head. Aroma is chocolate, marshmallow and toasty malt. Full bodied. Body is soft and pillowy - very marshmallowy. Flavor is bitter chocolate and or burnt malt. And vanilla notes. After awhile the chocolate approaches unsweetened baking chocolate. Quite dry and bitter despite the marshmallow aspect - definitely something to sip and savor.
