Before being combined in their distinctive, handcrafted Oregon pine Solera vat, the beautifully layered Glenfiddich 15 Year Old single malt Scotch whisky is creatively matured in three types of wood cask: sherry, bourbon, and new oak.

Every year, this Solera vat is kept at least halfway full rather than empty, producing a beautifully powerful and harmonic whisky that becomes increasingly complex and fascinating.
