Effect of reduced irrigation on grapevine physiology, grape characteristics and wine composition in three Pinot noir vineyards with contrasting soils
… has been extensively studied in different wine producing regions around the world, but little has ocurred in New Zealand. Pinot noir is the second most planted variety in the country and the most planted in Waipara. An improved understanding of the physiological responses of Pinot noir …

Heat wave mitigation strategies for wine grape production and measures of the impact of heat on berry ripening and wine composition
… in an increase in the level of alcohol in wine. This increase in alcohol content has been especially evident in red wines in Australia during the last three decades. Global warming evidence and forecasted more intense and longer heatwaves requires that mitigation strategies be investigated …

The Effects of Cluster Thinning on Vine Performance, Fruit, and Wine Composition of Pinot Noir (Clone 115) in the Edna Valley of California
… from each treatment was harvested and made into wine. Across all growing seasons, yield decreased 43% in thinned vines relative to un-thinned control vines. No effect of cluster thinning or interaction with growing season was found in vine shoot diameter, internode length, fruit zone light level, …

A study of Glycosides in grapes and wines of Vitis vinifera cv. Shiraz / Patrick George Iland.
Studies the links between grape composition, wine composition and wine sensory properties. Developed a new method of measuring glycoside concentration in grapes (glycosyl-glucose assay) and a modified measurement of wine colour density in red wine. These were used to analyse samples of Shiraz …

EXPLORING THE IMPACT OF PRESSING: FROM GRAPE COMPOSITION TO SPARKLING WINE PRODUCTION.
… of the must and, consequently, the wine produced with it. Therefore, the appropriate management of pressing leads to balanced chemical characteristics, in particular in terms of organic acid, potassium and pH, as well as the adequate extraction of aromas and their precursors, and …
