Chapter 14 Measuring Color in Wine: One Laboratory's Approach to Introducing a Color Measuring System

摘要

Wine Industry standard measures for describing color are simple absorbance values at 420 and 520 nm. Color space measurement systems such as CIELab offer a more precise tool for color management and can be applied to describe the effects of a wide range of wine making processes. The use of graphic presentations and the conversion of the a* and b* coordinates to Hue° and Chroma has helped greatly in introduction of the color space concept to new users.
