In terms of mixed drinks, shrub is the name of two different, but related, acidulated beverages. One type of shrub 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.[1][2][3]
The word shrub can also refer to 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.[1][4][5] 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.[3][6][7] Drinking vinegar is often infused with fruit juice, herbs and spices, for use in mixed drinks.[6][8][9]
