This is the world's oldest licensed whiskey distillery. The story of Bushmills dates back 400 years from the monks and alchemists and is the oldest Irish whiskey. Black Bush is Bushmills' premium blend. The concept for Black Bush was already developed in 1934. Compared to the regular Original, the percentage of malt whiskey is much higher and matured especially on Oloroso barrels. Bushmill gets the Sherry casks for maturing the malt whiskies from Bodegas Paez.
