The best-selling single malt in the world, Glenfiddich was founded in 1886. William Grant of Dufftown left his job as manager of Mortlach, another famous Speyside distillery, and started his own distillery. Glenfiddich is credited with popularising single malt whisky, when the decision was made in 1963 to bottle and promote Glenfiddich as a single malt. The Glenfiddich Select Cask has been matured in a combination of ex-bourbon, ex-red-wine and European oak casks, before being married in a solera vat.
