What are the stems of wine glasses for?

The stem of a wine glass serves several important functions:

- Temperature control: The stem provides a barrier between the hand and the bowl of the glass, preventing the wine from warming up too quickly.

- Grip: The stem allows the glass to be held comfortably and securely, without the risk of spilling.

- Aesthetics: The stem adds an element of elegance and sophistication to the glass.

In addition, the shape and size of the stem can affect the way the wine tastes and smells. For example, a long, narrow stem can help to concentrate the aromas of the wine, while a short, wide stem can allow for more air to circulate and enhance the flavor.
