The essential factor is that the mouth of the glass is slightly narrower than the body or bowl, we can observe this same principle in the graduated glass used by Scottish tasters, the graduations are there to allow precise additions of water. This shape allows aromas to rise to the nose in a progressive manner and militates against the use of very large brandy balloons, at least for analytical tasting. One cannot deny the imagery and the pleasure procured by cradling this type of glass in the palm of the hand.
