Which glass is typically used for serving a Stone Sour?

A Stone Sour is typically served in a sour glass, which is designed with a wider mouth and a slightly curved shape that allows the drinker to enjoy the aroma of the cocktail while sipping. This type of glass is particularly suited for drinks that contain citrus ingredients, like the Stone Sour, which combines whiskey, sweet and sour mix, and orange juice. The shape helps highlight the drink's orange and citrus notes, making the drinking experience more enjoyable.

The other glass types provided would not capture the essence of the Stone Sour as effectively. For instance, a cocktail glass generally has a wider rim and is more suited for straight-up drinks without ice, while a Collins glass is taller and used for drinks served with a mix or soda. Lastly, a rocks glass would typically be used for cocktails served over ice, but it would not provide the same sensory experience that a sour glass offers. Hence, the sour glass is the optimal choice for serving this particular cocktail.
