Question

In wine tasting, what term is used to describe the tracks of liquid that cling to the sides of a glass after the contents have been swirled, which is often said to be related to the alcohol or glycerol content?

Answer 1

Bouquet
A wine's "bouquet" refers to its aromas, especially those of a mature wine. If someone is referring to what they're smelling as "bouquet," it's usually a positive thing. Here's a bonus answer: Another term associated with bouquet is "tertiary aromas." Some people refer to three types of wine aromas: "primary," which is the aroma of grapes; "secondary" aromas of winemaking; and "tertiary" of bottle aging.
