The Bourbon Manhattan Cherry Shrub is a modern variation that adds cherry shrub - a drinking vinegar made from cherries, sugar, and vinegar - to the classic Manhattan formula. This contemporary riff brings tart, fruity complexity to the traditional whiskey and vermouth combination.

The Manhattan first appeared in newspapers in 1882 as a new style of cocktail. Jerry Thomas included it in his 1887 "Bar-Tender's Guide" using rye whiskey, sweet vermouth, and bitters. This classic remains one of the most iconic whiskey cocktails ever created.
