- n. a ring of clear liquid, forming into drops, near the top of a glass of fortified wine; the result of differential evaporation of alcohol and subsequent changes in surface tension
from the GNU version of the Collaborative International Dictionary of English
- n. drops which form and roll down a glass above the surface of strong wine. The phenomenon is due to the evaporation of alcohol from the surface layer, which, becoming more watery, increases in surface tension and creeps up the sides until its weight causes it to break.
