This paper aims at establishing distinctive elements regarding the authenticity of the following wines from the Apold vineyard: Sauvignon blanc, Fetească regală and Chardonnay. The paper aims at reviewing the color-giving components specific to white wines. Thus, through HPLC methods, we identified and quantified phenolic compounds which, in the end, presented total values between 86.085 mg/L and 89.272 mg/L. The present study also demonstrates the authenticity of these wines through spectrophotometric methods employed to determine the color of white wines. Based on the results obtained, we established that the studied wines are authentic, as the values resulted from the calculations in the procedure range between 0.015 and 0.019.
