Bushmills Original Irish Whiskey is triple-distilled single malt whiskey combined with an aromatic, lighter grain Irish whiskey, aged at least 3 years in Kentucky bourbon barrels & Spanish Oloroso sherry casks. This is the highest quality blended Irish whiskey from Ireland's oldest whiskey distillery. With a recipe that dates back before Prohibition, there is no better whiskey for making a classic, pre-Prohibition cocktail than Bushmills Original.
