This is the 2013 vintage of the 9.3% ABV Russian Imperial Stout from Widmer Brothers Brewing (we'll put aside for the moment the historical incongruity of using the Soviet KGB in the same name as Imperial Russia which met its demise at the hands of the Bolsheviks, and instead concentrate on the beer).
The beer pours black as anthracite coal. There is a quarter to half inch head of thick dark brown foam. The aroma is sweet, tangy, creamy, mocha and dark chocolate. The taste has all the aromas, and adds a little more coffee to the mocha, lots of rich chocolate, cocoa, dark chocolate, milk chocolate with a decidedly bitter cold coffee bitterness on the finish. It is both creamy smooth and well carbonated. Oh, this is one nice stout; if it is the KGB, it is the hot female agent who is trained to get secrets by seducing you.
