Shrub (drink)
In mixed drinks, shrub is the name of two related acidulated beverages. One is a fruit liqueur that was popular in 17th and 18th century England, typically made with rum or brandy and mixed with sugar and the juice or rinds of citrus fruit. The other is a cocktail or soft drink that was popular during America's colonial era, made by mixing a vinegared syrup with spirits, water, or carbonated water. The term can also be applied to the base, a sweetened vinegar-based syrup from which the cocktail is made; that syrup is also known as drinking vinegar. Drinking vinegar is often infused with fruit juice, herbs and spices, for use in mixed drinks.
