This is the second imperial stout I've had, ever (first was Stone Russian Imperial Stout, which I had about a year ago and loved). Crafted by BrewDog in Fraserburgh, Scotland, the Riptide "twisted merciless stout" won World's Best Imperial Stout at the 2007 World Beer Awards.
Pours very dark brown, essentially black with a hint of burgundy if you hold it up to the light, with a creamy tan head. Dark roasted malts produce notes of coffee, espresso, and dark chocolate in both aroma and flavor. This beer is smooth and silky, and surprisingly light (it is not heavy as most people would assume). The 8% ABV is noticeable in the aroma but not overpowering in the flavor. As the beer warms up, the flavors become even stronger. The best part of this beer is the finish - warm and smooth, with the lingering taste of dark chocolate... really good, bitter dark chocolate. A delicious brew!
