Brandy Snifter
A snifter (also called brandy snifter, cognac glass, or balloon) is a type of stemware, a short-stemmed glass whose vessel has a wide bottom and a relatively narrow top. It is mostly used to serve aged brown spirits such as bourbon, brandy, and whisky. The large surface area of the contained liquid helps evaporate it, the narrow top traps the aroma inside the glass, while the rounded bottom allows the glass to be cupped in the hand, thus warming the liquor.
