The Whistler range is produced by Boann Distillery and features an eclectic range of whiskey catering to all tastes. The Whistler 10-Year-Old Single Malt has been aged originally in American oak casks before a finishing period in oloroso sherry casks. The salty/savoury/fruity character that has been brought on by a finishing period in oloroso wood give this an extra level of depth and complexity.
