I've got one bottle of "Take The Black", just waiting for a chance to sit down and re-watch season one of GoT. I think pop the top at the same moment they raise the gate in the wall in the opening scene. Can't wait to try this one since Ommegang is so synonymous with top-shelf Belgain-style beers. Stouts are not exactly a style I think of with regards to them, but then again I've never had an Ommegang beer I didn't thoroughly enjoy. I'll be curious to read your take on it.
Earlier you mentioned Samuel Smith's Organic Chocolate Stout and I agree it's superb. Sublime even. Easily in my top 5 stouts along with Blvd. Dark Truth, North Coast Old Rasputin, Deschutes Obsidian, and Great Divide Yeti. Reminds me a bit of Tallgrass Buffalo Sweat, but more chocolatety with the addition of the Theobroma and a tick more toasty notes.
