William Grant's vision of creating the "best dram in the valley" led to the founding of Glenfiddich, where traditional techniques and innovative practices coexist. The distillery's unique triangular bottle and iconic stag emblem are recognized worldwide, symbolising a range of single malts that include the classic 12, 15, and 18-year-old expressions, as well as rare and experimental releases. Glenfiddich's use of a solera vatting process for its 15-year-old variant and dedication to single malt promotion have played significant roles in the global popularity of Scotch.
