What does the concentration scale in wine describe?

The concentration scale in wine specifically pertains to the intensity of color present in the wine. This scale is categorized into three levels: Pale, Medium, and Deep. Each of these terms relates to how concentrated the pigments are in the wine, which is often influenced by factors such as grape variety, winemaking techniques, and the particular wine's age.

When a wine is described as pale, it usually has a light color, often indicating lower pigment concentration, which is common in white wines or lighter red wines. A medium concentration indicates a balance of color intensity, which may suggest a fuller-bodied wine or one that has undergone more substantial extraction during winemaking. Deep concentration indicates a high intensity of color, often associated with highly pigmented grape varieties or wines that have been aged to enhance their richness and complexity.

Understanding the concentration scale is crucial for sommeliers and wine enthusiasts, as it provides insights into the wine's potential flavor profile, body, and overall style. The other options relate to different characteristics of wine, but they do not pertain specifically to the concentration of color in a wine, distinguishing the correct choice.
