EXPLORING THE IMPACT OF PRESSING: FROM GRAPE COMPOSITION TO SPARKLING WINE PRODUCTION.
… the knowledge gap existing with regard to grape, must, and base and sparkling wine composition based on the pressing conditions applied. Grape juice was obtained under laboratory-scale with the aims to select the pressing method for the (i) proper monitoring the grape ripening and (ii) the …

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 …

Using GPS, GIS & remote sensing to understand Niagara Terroir : Pinot noir in the Four Mile Creek & St. David's Bench sub-appellations
… some notable correlations between vineyard and grape composition variables, and spatial trends were observed to be qualitatively related for many of the variables. The MDS task revealed that wines from each vineyard were more affected by random fermentation effects than water status effects. …

Assessment of the spatial variability of vegetative status in vineyards using non-destructive sensors: Application of remote and proximal sensing technologies in precision viticulture
Introduction: The vegetative status of grapevines influences yield and grape composition. The assessment of the vineyard spatial and temporal variability in precision viticulture requires a large amount of data. Traditional methods are not suitable, as they are time and labour demanding, making the …
