70cl / 43% - Kaiyo's stock of Mizunara oak casks is its pride and joy. Known to impart a subtle and unusual collection of aromas and flavours to whisky during maturation, it's this wood which is often credited with setting Japanese whisky apart. Kaiyo doubles down on its cask maturation, sending the full casks off to sea for months at a time, allowing the natural motion to ensure constant movement, and thus contact between whisky and wood.
