Bourbon Meets Japan's Rarest Oak
Mizunara oak is famously difficult to work — porous, prone to leaking, and slow-growing — which is why so few whiskeys ever touch it. For this limited edition, the World Whiskey Society sourced handmade Mizunara barrels from Japan's shochu tradition and finished a high-corn Kentucky bourbon in them, adding an exotic layer of incense-like spice and sandalwood to classic bourbon sweetness. It is a collector's piece as much as a pour. Explore more from the World Whiskey Society collection.
Tasting Notes
Full-bodied and rich: deep caramel and vanilla from six years in American oak, lifted by the Mizunara finish — sandalwood, incense spice, and a distinctive aromatic woodiness layered over honeyed corn sweetness. The 108-proof palate is robust and warming, with a long, smooth finish.
How to Enjoy
Neat, to meet the Mizunara character head-on; a few drops of water open the spice. A natural centerpiece for a bourbon tasting flight built around cask finishes.
