Whisky Chivas Regal Extra 13 Year Old. This Chivas Extra 13 blended Scotch whisky selectively matured in Oloroso Sherry Casks is inspired by the Chivas brothers 13 King Street Emporium in Aberdeen, where they imported different spirits, exotic spices, and luxury food items from across the globe. Imparting its own unique combination of characteristics onto the Chivas blend, this finish brings new and contrasting flavour notes to the spirit for the first time.
