A big hit when it first hit the market in 2015, the Mars Maltage Cosmo is a blended malt from the little-known Shinsu distillery in the Nagano Alps. This bottling is a blend of Japanese and Scotch whiskies from undisclosed distilleries, resulting in a mysterious expression that’s full of chocolate, citrus and oak. Cosmo has become a permanent addition to the brand’s core range.
