As much as 65% of Glenfiddich 18 Year Old character comes from the wood it’s matured in— which is why Glenfiddich is one of the only distillers left to own an on-site cooperage—so our craftsmen can tend to every cask throughout maturation. Glenfiddich 18 Year Old undergoes a traditional vatting that combines Bourbon and Sherry wood, and is then married for at least three months in exceptionally small, individually numbered batches. This provides a unique depth and complexity that has been acclaimed by experts and has garnered a host of coveted industry awards.
