碣石山产区不同白葡萄品种性状及葡萄酒风味品质分析

Analysis of varietal traits and wine flavor characteristics of differentwhite grape varieties from Jieshi Mountain region

该文通过调查农艺学性状及病虫害分析葡萄品种适应性,结合相应葡萄酒挥发性物质与感官分析(选择合适项目法和定量描述性分析法),探究碣石山产区主栽白色酿酒葡萄品种‘霞多丽’、‘维欧尼’、‘胡桑’、‘阿拉奈尔’和‘小芒森’的酿酒特点。结果表明,5个品种农艺学性状表现良好,仅‘胡桑’抗病性较差,受绿盲蝽侵害较重,需相应防治措施。‘霞多丽’和‘维欧尼’酯类物质的浓度较高,表现为柑橘、柠檬、菠萝、香蕉和核果香气。‘胡桑’萜烯、降异戊二烯和一些酯类物质的浓度较高,表现为甜瓜、哈密瓜、苹果、梨、糖渍水果和花香。‘阿拉奈尔’C6/C9类、萜烯、苯类和内酯类物质的浓度较高,表现为青苹果、植物和花香。‘小芒森’高级醇、脂肪酸和果香硫醇类物质的浓度较高,表现为百香果、西柚、蜂蜜、坚果、矿物、动物皮毛、肉桂和煤油香气。根据《全球葡萄酒中国鉴评体系》,‘小芒森’整体品质得分较高,在碣石山产区可酿造成品质优良的甜型葡萄酒。

In order to reveal the adaptability,quality and wine-making characteristics of different white grape varieties,‘Chardonnay’,‘Viognier’,‘Roussanne’,‘Aranèle’and‘Petit Manseng’from Jieshi Mountain region were investigated through the research of growth status,volatile composition and sensory evaluation(Check-all-that-apply and Quantitative descriptive analysis).The results showed that the agronomic characters of five varieties were well behaved,except that‘Roussanne’had relatively poor resistance for the diseases and pests,which required corresponding prevention measures.‘Chardonnay’and‘Viognier’wines had high concentrations of acetates and fatty acid ethyl esters,and were characterized by the aroma of citrus,lemon,pineapple,banana,and stone fruit.‘Roussanne’wines were expressed as melon,cantaloupe,apple,pear,candied fruit,and floral notes,which might be contributed by terpenes,norisoprenoids,and some esters.‘Aranèle’wines were generally identified by the aroma of green apples,herbaceous and floral notes,with high concentrations of C6/C9 compounds,terpenes and volatile benzene compounds.‘Petit Manseng’wines had high concentrations of higher alcohols,fatty acids,and fruity thiol compounds,and were featured with the perception of passion fruit,grapefruit,honey,nuts,minerals,animal fur,cinnamon,minerals,and kerosene.According to the‘China Rating System for Global Wine’,‘Petit Manseng’from Jieshi Mountain region had potential to be made into sweet wines with high quality.
