Correlating wine quality indicators to chemical and sensory measurements

Molecules. 2015 May 12;20(5):8453-83. doi: 10.3390/molecules20058453.

Abstract

Twenty-seven commercial Californian Cabernet Sauvignon wines of different quality categories were analyzed with sensory and chemical methods. Correlations between five quality proxies-points awarded during a wine competition, wine expert scores, retail price, vintage, and wine region-were correlated to sensory attributes, volatile compounds, and elemental composition. Wine quality is a multi-faceted construct, incorporating many different layers. Depending on the quality proxy studied, significant correlations between quality and attributes, volatiles and elements were found, some of them previously reported in the literature.

Keywords: Cabernet Sauvignon; descriptive analysis; elemental analysis; quality proxies; volatile analysis; wine quality.
