A wine glass is a type of glass that is used for drinking or tasting wine. Most wine glasses are stemware (goblets), i.e., they are composed of three parts: the bowl, stem, and foot.
Before "glass" became adopted as a word for a glass drinking vessel, a usage first recorded in English c. 1382, wine was drunk from a wine cup, of which there were a huge variety of shapes over history, in many different materials. Wine cups in precious metals remained in use until the Early Modern period, but as glass got better and cheaper, were generally replaced everywhere except in churches, where chalices are still normally in metal.
