Bushmills Single Malt Whiskey 16 year old is truly one of the great whiskeys of the world. Aged for about 15 years in a combination of Oloroso Sherry and bourbon-seasoned casks, and then finished for about 9 months in port wine pipes (large barrels unique to making port wine.) This single malt shows its layers of flavor, juicy fruits, nuts and spice, as well as a hint of ruby redness. It’s best enjoyed neat. Okay, maybe one small cube of ice to open it up.
