Uniquely amongst Scotch whisky distillers, the Malt Master matures the Glenfiddich 15 Year Old in three types of oak cask, sherry, bourbon and new oak, to pervade it with rich fruit flavours and distinct spice and honey notes. Then marries it in the unique handcrafted Oregon pine Solera vat, which is always kept at least half full, to give it a beautiful balance and create a deliciously harmonious, consistent and complex whisky that gets increasingly complex over time. The Solera system is the culmination of curious minds and the pioneering spirit of Glenfiddich. Its also the secret behind this whisky becoming the first 15 year old expression to enter the top ten best selling single malts. Great for experiencing a premium, mature, rich, silky smooth malt with an intriguingly complex aroma and subtle, sweet layers of sherry oak, marzipan, cinnamon and ginger.
