Whisky Aberfeldy 12 Year Old. John Dewar knew the importance of nature in creating an unaltered quality whisky. That's why he chose the crystal clear water that gushes from the Pitilie Burn spring in the small village of Aberfeldy in Perthshire, in the Scottish Highlands, to create the unique whiskies that will bear his name. There he built the distillery that gives the heart of the Dewars Blends, the Aberfeldy Single Highland Malt Scotch whisky. It is a refined, multidimensional, limited edition malt, intended to be enjoyed slowly, plain or with a little water in order to better highlight its exquisite aromas. Its rich aromatic composition is one of the pleasures that one derives from the contact with this rare malt.
