Yamazaki Cask Umeshu (750 ml)

At the misty confluence of the Katsura, Uji, and Kizu rivers — the same soft-water aquifer that Sen no Rikyū drew from for his tea ceremonies — Suntory's Yamazaki Distillery has produced malt whisky since 1923. Yamazaki Cask Umeshu repurposes those same single

malt casks as maceration vessels for ume plums, meaning every batch carries the aromatic residue of American oak, ex-bourbon, or sherry wood that shaped the distillery's whisky before it shaped this liqueur.

The Yamazaki site's warm, humid microclimate — which accelerates whisky maturation faster than any other major Japanese distillery — acts on the ume maceration in kind, drawing stone-fruit intensity from the plums while the whisky-seasoned wood contributes layered vanilla, dried fig, and faint sandalwood.

The soft, low-mineral water drawn from the river-fed aquifer at roughly 25 m elevation integrates the plum extract without hardness or astringency.

The defining transgression here: where most commercial umeshu is produced in neutral spirit or shochu, this expression is built inside casks with a documented single malt history — the wood is not a neutral container but an active flavour contributor carrying the Yamazaki house character into the liqueur format.

No filtration or production parameters are officially disclosed for this expression. Drink now or cellar short-term; the cask influence will continue to evolve in bottle.
