Johnnie Walker, a brand of Diageo North America, unveiled White Walker, a collaborative, limited-edition Scotch whisky, in partnership with HBO hit series, “Game of Thrones.” The Scotch whisky was created by whisky specialist George Harper, alongside the team of expert blenders at Johnnie Walker, and is best served directly from the freezer, the company says. The Scotch contains notes of caramelized sugar and vanilla, fresh red berries, with a touch of orchard fruit and features Single Malts from Cardhu and Clynelish, it adds. Bottled at 41.7 percent alcohol by volume, White Walker by Johnnie Walker is available globally, including in all major airports starting this month until supplies last for a U.K. SRP: £32.00 for 750-ml bottle.
