Stemware

Stemware is drinkware where the bowl stands on a stem above a foot[1] (base that allows to put the vessel down onto a table).

[2] The snifters represent an exception, as they are designed to hold the bowl in a cup of the hand to warm up the beverage.

Prior to that, a typical drinking vessel made of glass was either a tumbler (unlike the modern ones, these have rounded bases and could literally tumble) or a pointed-base design intended for insertion into the ground or streambed for cooling.

The large bowls are used for nonalcoholic beverages (historically, they were also used for low-alcohol drinks, like beer or mead).

In particular, the French wine quality testing is performed using a special "INAO" glass with an egg-shaped bowl, short stem, and wide foot.
