3. Wine glass A wine glass is a type of glass stemware which is used to drink and taste wine. It is generally composed of three parts: the bowl, stem, and foot. Selection of a particular wine glass for a wine style is important, as the glass shape can influence its perception. Wine glasses made of fused or cut glass will often interfere with the flavor of the wine,as well as creating a rough, thick lip, from which it is not as pleasurable to drink.
