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 mixed with sugar and the juice or rinds of citrus fruit.
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. The term "shrub" can also be applied to the sweetened vinegar-based syrup, from which the cocktail is made; the syrup is also known as drinking vinegar. Drinking vinegar is often infused with fruit juice, herbs and spices for use in mixed drinks.
The early English version of the shrub arose from the medicinal cordials of the 15th century. The drink gained popularity among smugglers in the 1680s trying to avoid paying import taxes for goods shipped from mainland Europe: To avoid detection, smugglers would sometimes sink barrels of spirits off-shore to be retrieved later; the addition of fruit flavours aided in masking the taste of alcohol fouled by sea water. As a mixture of fruit and alcohol, the shrub is related to the punch, however punches were normally served immediately after mixing the ingredients, whereas shrubs tended to have a higher concentration of flavour and sugar and could be stored for later use, much like a pre-made drink mixer. The shrub was itself a common ingredient in punches, either on its own or as a simple mix with brandy or rum. It was also served during the Christmas season mixed with raisins, honey, lemon, sherry, rum and other spirits. The shrub was sold in most public houses throughout England in the 17th and 18th centuries, although the drink fell out of fashion by the late 1800s.
The American version of the shrub has its origins in 17th century England where vinegar was used as an alternative to citrus juices in the preservation of berries and other fruits for the off-season. Fruit preserves made in this fashion were themselves known as shrubs and the practice carried over to colonial America. By the 19th century, typical American recipes for shrubs used vinegar poured over fruit—traditionally berries—which was left to infuse anywhere from overnight up to several days; afterwards, the fruit would be strained out and the remaining liquid would be mixed with a sweetener such as sugar or honey and then reduced to make a syrup. The sweet-and-sour syrup could be mixed with either water or soda water and served as a soft drink, or it could be used as a mixer in alcoholic cocktails. Shrubs eventually fell out of popularity with the advent of home refrigeration.
The serving of vinegar-based shrub drinks became popular again in 2011 and 2012 in American restaurants and bars. The trend has also been noted in bars in Canada as well as London. The acidity of the shrub makes it well suited as an apéritif or used as an alternative to bitters in cocktails. Unlike cocktails acidulated with citrus, vinegar-based drinks will remain clear when shaken.
