Imperial Stout, also known as ?Russian Imperial Stout? is a variety of ale that was originally brewed in England for export to the court of the Tsar of Russia. Its high level of hopping is intended to preserve it during long trips and to provide a more bracing drink against cold climates. The color is very dark, nearly opaque black. Imperial stout exhibits enormously powerful malt flavors, hints of dark fruits, and is often quite dry.
