What type of glass is typically used for serving whiskey?

The correct answer is the rocks glass, which is specifically designed for serving whiskey neat or on the rocks. This type of glass has a wide, heavy bottom that allows for easy stirring and provides stability when filled with ice. The shape of a rocks glass is conducive to appreciating the aromas and flavors of whiskey, enabling drinkers to enjoy their spirits in a way that enhances the tasting experience.

A highball glass is generally taller and used for mixed drinks that require soda or tonic water, thus it is not ideal for serving neat spirits. The Collins glass, similar to the highball but usually even taller, is typically reserved for cocktails that are served with a larger volume of mixer. The martini glass, with its signature conical shape, is designed for cocktails that are shaken or stirred with ice and then strained, which is not suitable for straight whiskey. Therefore, the rocks glass stands out as the most appropriate choice for serving whiskey.
