Whisky Compass Box Great King Street Glasgow Blend. Introduced to the Great King Street range by Compass Box in 2014, the Glasgow Blend is a superbly full bodied blended Scotch whisky. It's made with 33% Lowland grain whisky and 67% malt whisky from the Highlands, Speyside and Islay, aged in a combination of first fill and refill ex bourbon barrels and first fill Sherry casks, with a small portion being finished in new French oak. Plentiful amounts of Sherried fruit touches surrounding a core of peaty notes yummers.
