Most of us think of these as martini glasses, but in the official bartending world, they're cocktail glasses. Designed to hold chilled drinks without ice, the distinctive long-stemmed glasses with the cone-shaped bowl range in size from 4 to 10 ounces. The long stem allows you to hold the glass without warming the drink with your hands. It's best to opt for the smaller glasses; the larger ones are too difficult to carry around without spilling. These glasses hold 7 ounces and are dishwasher safe. Try making this Concord Grape Martini recipe in a martini glass.
