HPLC-DAD-MS determination of colored and colorless phenolic compounds in Kalecik Karasi wines: effect of different vineyard locations

Abstract

Phenolic composition of wines from Kalecik karasi, a native grape variety grown in Turkey, and influence of different vineyard locations on these compounds were investigated. High performance liquid chromatography-diode array detector (HPLC-DAD) and mass spectrometry (MS) were used for the phenolic compound analysis. Fourteen anthocyanins, six flavanols, twelve phenolic acids, and six flavonols were identified and quantified. It was observed that total phenolic content in wine from Ankara region was clearly higher than in wine from Nevsehir. Sensory analysis was also used to investigate the influences of the vineyard location. Based upon sensory analysis, the wines obtained from Ankara region had higher color, harmony, astringency aftertaste, astringency, flavor, and body character than wine from Nevsehir.
