Johnnie Walker Gold Label Centenary Blend is a blend of 15 different whiskies which each are all at least 18 years old. Johnnie Walker Gold Label Centenary Label was created by Sir Alexander Walker in 1920 to celebrate the founding of the company hundred years earlier. Although discontinued during the war due to shortage of blending stocks, the label was reintroduced in 1992, with a blend based upon the original blending notes left by Sir Alexander seventy-five years earlier. In 2009 the bottle and box where reshaped and available until 2013 when Centenary phased out in favour of the current NAS expression Gold Label Reserve. This is the second version, introduced around the turn of the centenary and actually renamed ‘The Centenary Blend’.
