The Signature Speyside Malt. Duty Free Exclusive. Tamnavulin is the Gaelic translation for Mill on the Hill, named in part after the historic woollen mill which sits on the site of the distillery. Always Double Cask Matured: Matured in American White Oak and finished in Tempranillo red wine cask for a rich, fruity finish to complement the sweet, mellow flavour of Tamnavulin. Crafting exceptional Single Malt whiskies with a true Speyside character, the initial maturation takes place in American oak ex-bourbon barrels, then, a selection of the spirit is transferred into ex-Tempranillo red wine casks originating from Spain. Tempranillo red wine casks are rarely used for finishing and finessing whiskies. It is a black grape variety originating from Spain renowned to produce rich, full-bodied red wines. A rich, sweet and mellow Speyside whisky. Ideal for those who are new to whisky as well as connoisseurs. Exclusive to travellers
