Plum wine is a type of fruit wine made by fermenting plums, typically using the fruit's juice, pulp, and sometimes the whole fruit. It is popular in various cultures, especially in Japan, where it is known as umeshu. The wine is often sweet and has a fruity flavor, making it a refreshing drink. The production process involves macerating the plums with sugar and allowing them to ferment with yeast. After fermentation, the mixture is strained, and the resulting liquid is bottled. Plum wine can be enjoyed on its own, used in cocktails, or served as a dessert wine.
