Yamazaki 55 Year Old - Yamazaki 55 Year Old was distilled in 1960 and matured in a mizunara cask until 1964. It was then transferred to a white oak cask for the remainder of the maturation process. 1964 was the year that hosted the previous Tokyo Olympics, making this a rather timely release from Suntory, in a year that was meant to see athletes and sports fans from around the world descend on Tokyo once more.
