In 2013 Dalmore extended their core range of stunning whiskies with the Dalmore 25 Year Old. As a distillery that has a history of using an intricate selection of maturing methods, the 25 Year Old continues that tradition. First, it matured in American white oak cask. After that, it was hand-divided into 25 year old Palomino Fino sherry butts and 1980s first-fill bourbon casks. These whiskies are then married together in bourbon barrels and finished in Tawny Port pipes from Portugal.
