The Code of Federal Regulations (U.S. Internal Revenue Service, 1961), has set a limit on color of white wines so treated expressed as `no less than 0.6 Lovibond in a one-half inch cell.' The present official method of analysis related to a K-dichromate standard curve the A430 readings of the wines as measured by a spectrophotometer with certain prescribed characteristics. Expression of dissatisfaction with the method in practice provided the stimulus for the study reported here. A review of the historical background leading to the official designation of the present method is followed by a critical analysis of the method itself. Experimental evidence is presented which proves its inadequacies and indicates the need for reopening for further consideration the question of evaluating white wines to conform to Federal Regulation.
