The Bushmills 21 Year Old Single Malt Irish Whiskey is aged for a minimum of 19 years in former Oloroso sherry and bourbon-seasoned casks, then transferred into Madeira casks for a further two years. It has huge depth that interweaves dried fruit flavours with a spicy, aromatic maltiness and subtle nutty raisin notes. This triple distilled whiskey should always be served neat.
