Many professional whisky tasters will use a tulip shaped glass such as copita glass. The tulip shape helps to funnel the aromas and concentrate them around the rim of the glass, making them easier to smell. A standard tumbler glass, with its straight sides, dissipates the aromas more readily, making them less easy to smell above the glass. Therefore, while there are many different whisky tasting glass designs to choose from, the only recommendation is to avoid the tumbler style glasses.
