Bushmills 21 Year Irish Whiskey is the epitome of excellence in the world of Irish spirits. Crafted with meticulous care and aged for an astounding 21 years, this single malt whiskey is a testament to the distillery's commitment to quality and tradition. It undergoes a unique aging process, first spending a minimum of 19 years in former Oloroso Sherry and bourbon-seasoned casks, and then being transferred into Madeira casks for an additional 2 years of aging and maturation. This extraordinary journey through different cask types results in a whiskey of unparalleled depth and complexity.
