Unless you’re serving it on ice, the martini really is one drink where you almost have to have a martini glass to truly enjoy it. Fortunately, martini glasses come in a variety of styles and qualities to match your desired level of sophistication. Martini glasses are a beneficial addition to the at-home bar because they do double-duty for other drinks as well; use them when you serve other popular cocktails such as the classic Manhattan or the trendy Cosmopolitan.
