Nàdurra is the purest expression of The Glenlivet. Crafted using traditional 19th century methods (small batch production, non chill-filtered) which, research shows, appeals to the Malt Whisky Connoisseur. Nàdurra Oloroso is a new extension to the range, and it is matured exclusively in highly prized Oloroso Sherry casks. The casks impart flavours of dried fruit and warm spices to the whisky.
