Abstract

The color of wines, in addition to reflecting some qualitative characteristics, such as tactile sensations, age, and state of preservation, has great marketing importance, with consumers selecting wines according to their preferred color. The reduction in maceration time varies according to the type of grape and probably with the climatic conditions of each harvest. For the production of young wines, it has been observed that excessive maceration can reduce the intensity of color, and this finding meets the winemaker's anxiety to obtain wines that are more colorful, with a more stable color, less astringent, and in a shorter production time.
