Kurayoshi Umeshu Whisky (700 ml)

Matsui Shuzo, operating from the foothills of Mt. Daisen — Tottori Prefecture's 1,729 m extinct volcano — built its house style around one geological asset: deep-aquifer groundwater filtered through volcanic rock, which strips hardness and amplifies the soft, fruit-forward sweetness that defines every expression in the range. The Umeshu Whisky applies that same water philosophy to a liqueur format, macerating Japanese ume plum into a blended malt whisky base rather than the neutral spirit or shochu used by most domestic umeshu producers — a deliberate category transgression that anchors fruit character to malt complexity.

The base spirit belongs to Kurayoshi's Pure Malt tier: a blend of sourced Scotch single malt and Japanese malt whisky, matured in ex-bourbon American white oak in Tottori's extreme Sea of Japan climate, where seasonal swings from near-freezing winters to 38 °C summers accelerate cask extraction. That thermal cycling drives vanilla and dried-fruit extraction from the oak, which the ume maceration then amplifies rather than masks. Specific maceration duration, ume variety, and final ABV are not publicly disclosed by the producer.

What separates this from standard umeshu is the malt backbone: where rice-spirit or neutral-base umeshu delivers one-dimensional stone fruit, the whisky base introduces grain depth, light oak spice, and the faint almond character typical of the Kurayoshi 12yr profile — making this a crossover format with genuine whisky structure beneath the plum sweetness.
