A millenia of tradition, Bushmills is one of the very few Irish Malt whiskeys available. Each drop of Bushmills Malt is carefully distilled three times and is made from 100% malted barley. One of the world's most distinctive fine spirits and ancients marques, the Bank of Northern Ireland issued a series of sterling banknotes that feature an illustration of the Old Bushmills Distillery. Bushmills 10 Year Old is treated to an extended period of maturation for at least ten years in American oak barrels that have previously been used to age bourbon.
