由于葡萄酒需要客观的称谓标准，加州葡萄品种。调查了48种霞多丽葡萄酒中的几种香气化合物，包括酯类化合物、降异戊二烯类化合物和萜类化合物。对感官数据的统计分析表明，挥发性香气的浓度首次与描述性分析分数直接相关，这与地区独特性和区分性有关。行业质量专家用来描述来自四个地区的葡萄酒的10个术语的感官得分与30多种葡萄酒化合物的浓度进行了比较。葡萄香气术语的使用频率与芳樟醇、1，1，6-三甲基二氢萘、3-甲基丁酸乙酯、2-羟丙酸乙酯和2-苯乙醇显著相关(p<；0.05)。芳樟醇浓度也与α-松油醇相关。此外，在加州所有地区的霞多丽葡萄酒中都发现了4-松油醇、香叶醇、橙花醇和芳樟醇氧化物(呋喃)。可..。
Since objective measures of appellations are needed for wine, California Vitis vinifera Var. Chardonnay wines (n = 48) were surveyed for several aroma compounds including esters, norisoprenoids, and terpenes. For the first time concentrations of volatile fragrances were directly correlated with descriptive analysis scores that statistical analysis of the sensory data showed were associated with regional uniqueness and distinctness. Sensory scores for 10 terms used by industry quality experts to describe wines from four regions were compared to the concentrations of over 30 wine chemical compounds. Frequency of use of individual grape-based aroma terms were significantly correlated (p < 0.05) with linalool, 1,1,6-trimethyldihydronaphthalene, 3-methylbutyl acetate, ethyl 2-hydroxypropanoate, and 2-phenylethanol. Linalool concentrations were also correlated with α-terpineol. Also, 4-terpineol, geraniol, nerol, and linalool oxide (furan) were found in Chardonnay wines from all of the regions of California.
