Abstrakt: The article focuses on measuring and monitoring phenolics in red wines and musts. Among such compounds include anthocyanins, which are colored substance in grapes and young wines and tannins, which contribute to color and mouthfeel. Based on the results of a 2006 study, ultraviolet (UV)-visible spectroscopy could reliably be used to develop a predictive model of phenolics in wine compared with near infra-red spectroscopy.
