Bamboo is a vintage sherry-based cocktail featured in several classic cocktail books. The recipes vary in ratio, but they mainly include equal parts dry vermouth and sherry, typically fino or oloroso, and a dash of bitters. Apart from the standard version, this cocktail is sometimes altered by replacing dry with sweet vermouth or the addition of simple syrup.
To make the cocktail, vermouth and sherry are poured into a glass and stirred. Bamboo is usually enjoyed as an aperitif. It is traditionally served in a coupe glass, garnished with an orange twist. Bamboo is an old cocktail with a vague history. By the early 1900s, it was already prominently featured on cocktail menus, and it is assumed that it originated sometime in the 1880s.
