Abstract:

The aroma description for 4 kinds of Shiraz wine was subjected to multivariate statistical analysis. Principal component analytical results indicated that 2 principal components provided 90.15% cumulative contribution. Systematic cluster analysis exhibited that 4 factors including pepper (or roasted), spicy (or berry or rose or sweet fruit), licorice and chocolate (or pineapple) could reflect most information on the aroma of Shiraz wine. Therefore, these 4 terms were used as the description of aroma for sensory evaluation. It could simplify terms of sensory evaluation and improve the precision and sensitivity of sensory evaluation.

Key words: Shiraz, wine, description, sensory evaluation, multivariate statistical analysis
