Umeshu +

Umeshu is a Japanese liqueur made by steeping ume plums (while still unripe and green) in shōchū and sugar. It has a sweet, sour taste, and an alcohol content of 10–15%. Famous brands of umeshu include Choya, Takara Shuzo and Matsuyuki. Varieties are available with whole ume fruits contained in the bottle, and some people make their own umeshu at home.

Japanese restaurants serve many different varieties of umeshu and also make cocktails. Umeshu on the Rocks (pronounced umeshu rokku), Umeshu Sour (pronounced umeshu sawa), Umeshu Tonic (with tonic water), and Umeshu Soda (with carbonated water) are popular. It is sometimes mixed with green tea (o-cha-wari) or warm water (o-yu-wari). Umeshu can be served at different temperatures; chilled or with ice, room temperature, or even hot in the winter.
