Scotland, Speyside. Distillery operational. Owners: Chivas Brothers Ltd, Pernod Ricard

Chivas Brothers' flagship malt, The Glenlivet was widely introduced to the international scene and became one of the world's most popular Scottish malts in the early 1950s. Its owners completed something of a Herculean task, releasing Glenlivet in a number of different age expressions in the 1960s, including a 12, 15, 18 and 21 year old. Then, in the 1970s, it released superb vintage versions distilled 1959 and 1961, alongside the famous 12 year old, before beginning the new millennium with an outstanding range in the style of the day, The Glenlivet Cellar Collection. In terms of independent bottlings, it was under the colourful label “Glenlivet Whisky, George & JG Smith”, which paid tribute to the distillery's founder (also a colourful figure in the whisky industry in the 19th century), that bottlers released the malt, including Gordon & MacPhail who once again stood out with remarkable editions heavily influenced by sherry.

A Glenlivet released in a limited edition of 3,350 bottles in 2013 with very little information on the bottle to encourage consumers to focus on the whisky without any preconceived notions. Glenlivet's master distiller, Alan Winchester, later revealed that the whisky had been aged entirely in first-fill Scotch whisky barrels, meaning the malt is free from any bourbon or sherry influence, as would normally be the case. The rest remains a mystery.
