A chilled martini or coupe is the ideal serving glass because a cosmopolitan is typically shaken and served up, meaning without ice. The stemmed glass keeps the drink cold without warming it from your hand, and the bowl design helps concentrate and present the citrusy aroma as you sip. The other glasses are designed for different styles: an old fashioned glass is for drinks served on the rocks in a short tumbler, while highball and Collins glasses are tall, meant for longer mixed drinks with more ice and volume. Those options would dilute and alter the classic cosmopolitan experience.
