Japanese Crafts Fruit Cocktails Base Plum Sour (1.8 L)

Kitaoka Honten has operated from the entrance to Yoshino-Kumano National Park since 1868, when the seventh-generation head Sojuro consolidated four centuries of Kitaoka family commerce into sake brewing alone — a deliberate narrowing that sharpened the house's botanical instincts rather than diluting them. That same precision now drives the brewery's fruit liqueur range, produced via botanical infusion of seasonal fruits steeped in alcohol with sugar syrup, a method that preserves raw aromatic character rather than cooking it out. The Plum Sour base draws on Yoshino's soft mountain water — Oku-Yoshino Forest Water (奥吉野の森林水), drawn from forested highland streams and characterised by low iron content — which produces a gentle, mineral-neutral carrier that keeps the plum's tartness clean and unmuddied. What sets this expression apart within the category is its 1.8 L izakaya-format volume, engineered explicitly as a cocktail base for high-throughput service rather than sipping, positioning a craft-brewery product squarely inside the professional bar programme. The sour profile is calibrated for direct dilution with soda or shochu, delivering consistent acidity and stone-fruit intensity across every pour without batch variation.
