What aspect of wine is indicated by a wine’s "body"?

The term "body" in wine refers specifically to the weight and richness that a wine imparts on the palate. It describes how full or light a wine feels when tasted, reminiscent of how one might perceive the differences between a glass of skim milk versus whole milk. A full-bodied wine tends to have a higher alcohol content and greater concentration of flavors, making it feel heavier and more substantial in the mouth. On the other hand, a light-bodied wine is typically more refreshing and has a more delicate presence. This concept encompasses various factors, including the wine's alcohol content, sugar levels, and the presence of tannins, all of which contribute to the overall perception of body. Understanding the body of a wine helps in pairing it with food and appreciating the wine's complexity and structure.
