The Plum Highball is a tall, sparkling cocktail that combines plum flavor with a lighter highball structure. The fruit contributes a tart, wine-like sweetness, while carbonation keeps the drink crisp and easy to drink. Its long format makes it more refreshing than a short, spirit-forward cocktail, with the plum note lingering after each sip. The drink is listed as one of the bar's named cocktails and sits within a broader Japanese-influenced drinks menu.
