Abstract
Spectrocolorimetry in wines is analyzed within the context of the CIE recommendations and applicable standards in measurements and quality control (ISO 9 000). A methodology is presented for wine color measurements with traceability to the spectrocolorimetric scale. The concept of uncertainty in color measurements is emphasized as necessary to the intercomparison of measurements performed by different operators, at different times, different locations and with diverse instruments so that color communication is possible without misunderstanding. The layout of a norm is described involving all phases from concept to details on sample preparation. Applications on color of wine measurements in Port Wine are presented for model validation and to show the possibility of the study of the effects on influential parameters such as temperature, pH, sugar contend and aging. Reference to the application of the procedure to the control of wine color in blends is also described.
