Tomintoul Speyside Glenlivet 15 Years Old Portwood Finish has been created by the careful selection of aged whisky “finished” in Port wood. The malt whisky was transferred from Bourbon casks into the hand-picked Port pipes to "end" its maturation for a generous period of time. This process of “ending” grants the whisky refined characteristics, most notably, tones of fruity Port sweetness. Tomintoul's Master Distiller deemed that the time was right to bottle the whisky at 15 years of age when the malt whisky flavour notes had achieved harmony with the sweet attributes of the Portwood.
