Historically, the beverage called a shrub was created using fruit, sugar, and alcohol such as brandy or rum. It was a way to preserve fruit to drink. It was fermented, strained, and served over ice with water or soda water.
Today, a shrub is made with vinegar instead of alcohol and fermented. Spices or herbs may be added. The fruit is strained out and vinegar such as apple cider, balsamic, sherry, or red wine vinegar is added.
