A cocktail glass is a stemmed glass with an inverted cone bowl, mainly used to serve straight-up cocktails. The term cocktail glass is often used interchangeably with martini glass, despite their differing slightly. Today, the glass is used to serve a variety of cocktails, such as the martini and its variations (Gibson, French martini, vodka martini, espresso martini, appletini), Manhattan, Brandy Alexander, pisco sour, Negroni, cosmopolitan, gimlet, and the grasshopper.[1]
