AB Standardization of the color of each non-vintage is an important duty, but color specification is difficult. In this article we investigate empirical models using Scheffé polynomials to describe color response surface for four Rioja wine mixtures. The accuracy of color response prediction is shown as color differences in CIELAB units. The color response surfaces are visualized by preparing contour plots that depict color variation over a compositional region.
