SIZE: 750mL PROOF: 80 (40% ABV) Aged for 19 years in ex-American bourbon and ex-Spanish sherry casks, this rare Irish whiskey is then married together for an additional two years in madeira-infused casks. Bushmills has recently changed its designs, and as the original labels are being phased out, there is still a chance that you might receive a bottle different than what is in the picture. Rest assured, the liquid remains the same, regardless of the design.
