Tonight I’m trying thee 2012 version of Sierra Nevada’s Narwhal Imperial Stout.  It’s described as “midnight black and bold – with notes of baker’s cocoa and dark roasted coffee.”  It’s definitely dark and bold.  There’s a large head that dissipates quickly, and the nose has cocoa and lots of earthy notes.  The middle is dry and dusty, and bitter with that heavily roasted coffee.  The finish is actually kind of hoppy, with citrus and some spices, but there’s still some malty molasses flavor to balance it out.  It has a bit more carbonation that I expect in a stout of this this style and alcoholic content. (10.2% ABV)  All in all a good, but not great imperial stout.
