What type of glass is used to serve a Rob Roy?

A Rob Roy is traditionally served in a martini or cocktail glass. This choice is fitting because the martini glass is designed to showcase the visual appeal of the drink, which is typically a vibrant mixture of whiskey, sweet vermouth, and a dash of bitters. The shape of the martini glass, with its wide bowl and narrow stem, allows the aromas of the whiskey and vermouth to be enjoyed as the drinker sips.

The use of this type of glass also aligns with the drink's origins; the Rob Roy is essentially a Manhattan made with Scotch whisky instead of bourbon or rye, and the Manhattan is a classic cocktail served in a similar glass. Therefore, the martini or cocktail glass is the appropriate and traditional choice for serving a Rob Roy, ensuring it is presented elegantly and enjoyed properly.
