response of vitis vinifera cv tempranillo to partial rootzone drying in the field water relations growth yield and fruit and Wine Quality
Agricultural Water Management, 2009Co-Authors: D S Intrigliolo, J R CastelAbstract:Abstract This paper reports the effects of irrigation amount and partial rootzone drying (PRD) on water relations, growth, yield and Wine Quality of Vitis vinifera cv. ‘Tempranillo’ during two consecutive years in a commercial vineyard with a deep, light-clay soil located in Requena, Valencia, Spain. Partial rootzone drying applied at two amounts (100% and 50% of the estimated crop evapotranspiration), was compared to conventional drip irrigation, and also to rainfed vines. Results showed that the effects of irrigation amount on yield and Wine Quality were different between years. In 2003 with low yield values (around 6.3 t ha−1) irrigation did neither affect grape production nor Wine Quality. However, in the following year, with much higher general yield (17 t ha−1), the high irrigation dose increased yield by 30% compared to rainfed vines and it also increased must total soluble solids and Wine alcohol content. In both seasons, PRD did not significantly affect physiological parameters, nor growth, yield or fruit and Wine Quality, when compared to the same amount of water applied by conventional drip irrigation. Overall these results suggest that, under our experimental conditions, it was the irrigation amount rather than the system of application what affected vine performance, indicating the difficulties of successfully employing the PRD type of irrigation with a drip system in heavy and deep soils.

Establishment of the Wine Quality Evaluation Model
The Open Automation and Control Systems Journal, 2014Co-Authors: Shaodong Chen, Song LiangAbstract:In accordance with data provided from Mathematics Modeling Competition for National University students in 2012, it can be found whether grapes are high-Quality or not as well as the direct relationship between the grape and Wine Quality by means of SPSS and other statistical softwares, through multivariate statistical analysis and data analysis, and by verifying the credibility what comments made on Wine Quality by members of liquor, additionally, Quality classification on grapes is made through factor analysis. The physical and chemical indicators detected from Wine and grapes reflect their Quality to a certain extent. Through analysis of relationship between physical and chemical indicators concerning grapes and Wine, a mathematical model used for evaluating Wine Quality with the help of physical and chemical indicators concerning grapes and Wine is established, providing references for accurately evaluating Wine Quality.

Study on the Wine Quality evaluation model
BioTechnology: An Indian Journal, 2014Co-Authors: Chen Shaodong, Song LiangAbstract:According to the data supplied by the National University Colleges Mathematics Modeling Competition in 2012, we can find that whether the grapes are good or not, and the direct relationship between the grapes and the Wine Quality by the help of the SPSS and other statistical softwares, by comprehensively utilizing the method of multivariate statistical analysis and then carrying out data analysis, by distinguishing the credibility that members of liquor comment on the Wine Quality, and by utilizing the factor analysis to make Quality classification on the grapes. The physical and chemical indicators detected by Wine and grapes reflect the Quality of Wine and grapes to a certain extent. Analyzing the relationship among the physical and chemical indicators of the grapes and Wine, we establish a mathematical model evaluating the Wine Quality by utilizing the physical and chemical indicators of the grapes and Wine, which provides some references to accurately evaluate the Wine Quality in practical problems.

Wine Quality and regional reputation hedonic analysis of the bulgarian Wine market
Eastern European Economics, 2005Co-Authors: Nivelin NoevAbstract:This paper develops a hedonic pricing model to estimate the effects of Wine Quality and regional and varietal reputation on prices in the Bulgarian Wine market. We show, most importantly, that Wine Quality has a significant and positive impact. Red Wines of local varieties have diminishing reputations, while white Wines from local varieties have improved their standing in consumers' preferences. Our results reveal that there is significant regional reputation effect as well--at least for now--with Wines sold with significant price discounts compared to Svishtov cabernet sauvignon Wines. Over time, price discounts are rapidly diminishing for white Wines and increasing for red Wines, and regional reputations are losing significance, with an increase in the coefficients. We also show that product differentiation is important when transition markets are discussed. Regional specialization in production of a certain type of Wine is displayed, and regional reputation depends strongly on it. Finally, the age of the Wine has a strong positive and significant impact on market prices for red Wines but is insignificant for white Wines.

Current viticultural techniques to mitigate the effects of global warming on grape and Wine Quality: A comprehensive review.
Food research international (Ottawa Ont.), 2020Co-Authors: Gastón Gutiérrez-gamboa, Wei Zheng, Fernando Martínez De TodaAbstract:Climate is the main factor affecting grape and Wine Quality in Mediterranean viticulture. Global warming provokes an increase in the accumulation of soluble solids in grapes, together with a lower content of anthocyanins and acidity. This result in stuck and sluggish fermentations causing economic losses in the Winery. Climate adaptation strategies are essential to minimize the detrimental effects of global warming on grape and Wine Quality. This review summarized the effect of viticultural techniques to delay grapevine ripening with emphasis on canopy management and we overviewed the effects of high temperatures on grape and Wine Quality. Some viticultural techniques such as severe shoot trimming, minimal pruning, late winter pruning and apical leaf removal may delay grapevine ripening close to 15 days. Forcing regrowth is the most interesting technique since it allows to delay grape ripening at least of two months which can be essential in warm grapevine production areas.
