不同熟性酿酒葡萄果实品质及酿酒特性研究

Fruit profiles and vinification characteristics of wine grapes with different maturity cultivars

以陕西省杨凌地区不同熟性红色酿酒葡萄丹非德、嘉年华、梅尔诺、黑比诺及赤霞珠为试验原料,基于酿酒葡萄在杨凌地区的抗病性表现及葡萄果实中多酚物质的测定结果,结合单品种酿造酒的感官分析、酚类物质的组分及含量等指标的测定,分析不同熟性红色酿酒葡萄的果实品质与酿酒特性,以期筛选出最适于杨凌气候条件的红色酿酒葡萄。结果表明,该地区种植的早熟性酿酒葡萄病害较轻,但其糖类化合物积累量很低,不利于高品质葡萄酒的酿造;虽受本地气候因素影响,中晚熟性酿酒葡萄病情指数高于早熟品种,但其糖及多酚类物质积累状况较好,葡萄酒的感官品质也优于早熟品种。

Dornfelder（DF）,Garanior（GA）,Merlot（ML）,Pinot Noir（PN）and Cabernet Sauvignon（CS）were used as the research objects herein to analyze the diseases resistance,content of phenolic compounds,organoleptic qualities and phenolic compounds of wines to select suitable cutivars for Yangling area. The results showed that the climate condition of Yangling is more suitable for planting middle and late mature grape varieties. Although the fungal disease susceptibility level of medium and late mature varieties was higher than that of early mature varieties,they showed better accumulation of carbohydrates and polyphenols and better sensory quality of wine.
