Mars Maltage "Cosmo" Wine Cask Finish is a blended whisky bottled at 43% ABV and given an extra period of maturation in wine casks. For a new drinker, that usually suggests a softer, fruit-led style with some added sweetness and gentle oak.
As a blend, it is generally aimed at balance and approachability rather than intense power. The wine cask finish is likely to bring a rounder texture and hints of red-fruit character alongside the whisky's malt and wood notes.
