An extremely rare bottle from The Owner's Cask Series that Suntory started sometime in late 90s or thereabouts... An extremely limited number of single casks were dumped of which very few were over 12y, even less were sherry Butts, and most of the barrels came from the Yamazaki Distillery in Osaka/ So to find a Hakushu Sherry Butt with enough age to turn the whiskey black is a real treat.
