The ideal gift! Price and reviews available for Nikka Coffey Grain Whisky - 750ml Bottle. Nikka operates two Coffey stills (named after its inventor Aeneas Coffey) within the Miyagikyo distillery for the elaboration of its grain whiskies. Imported from Scotland in 1963, these old stills yield a distillate with more flavour and depth than modern column stills, imparting a distinct character that defines the house blends. These two unique bottlings showcase the innovative spirit of Nikka.
