The Glenrothes Distillery has always been universally acclaimed by blenders as an exceptional Speyside Malt. The Glenrothes is used in blended scotch whiskies such as Cutty Sark and The Famous Grouse. The Glenrothes bottlings are not determined by age but by vintage, making this single malt unique in its category. The Glenrothes is also sold as “Select Reserve,” a recently introduced non-vintage line.
