Johnnie Walker is a brand of blended Scotch whisky, part of the Diageo drinks group. The name draws on the legacy of John ‘Johnnie’ Walker, who was the first to sell whisky in his grocer’s shop in Ayrshire, Scotland, including his own production whisky under the name Walker’s Kilmarnock.

In 1865 John’s son Alexander produced their first blend, Walker’s Old Highland. From 1906–1909 John’s grandsons George and Alexander II expanded the line and introduced the colour names. Red Label  is a blend of around 35 grain and malt whiskies. Black Label blends around 40 whiskies, each aged at least 12 years.

Green Label is a vatted malt whisky that contains 15 individual single malts, the signature malts being Talisker, Cragganmore, Linkwood, and Caol Ila , average age of 15 years. Gold Label represents an extremely rare blend of over 15 single malts, including the very rare Clynelish malt. It was derived from Alexander II's blending notes for a whisky to commemorate Johnnie Walker's centenary.

Blue Label is Johnnie Walker's ultimate blend. Every bottle is serial numbered and sold in a silk-lined box, accompanied by a certificate of authenticity. Although no age is declared, it is believed that the whiskies blended are aged for over 25 years.
