Glenfiddich 15 Year Old Solera

The Solera system is unique to Glenfiddich in the Scotch whisky world and uses an idea borrowed from Spanish sherry-makers.

The Glenfiddich Solera Vat holds around 37,000 litres and has been kept at least half full since it was built and filled with 15 year old Glenfiddich in 1998. As 15 year old Glenfiddich whisky is always used to refill the vat, the whisky is allowed to be given a "15 year old" age statement. But, since the vat has never been emptied, a little of every batch that has ever been in the vat remains behind, mixing with the next batch and creating an award-winning whisky that has much greater depth and character than its 15 years might suggest.
