Terroir study and pragmatic approach to decide the best practices at the scale vineyard area
The principle terroir of studies consists of mapping environmental factors and characterizing the viticultural potential.
GiESCO 2013 – Session 5: Vineyard management, yield, quality
Agroforestry and viticulture: results of a 11-years study on the production and vigour of the vines
The ancient practices for cultivating vines often associated vines with trees. Traditionally, the trees provided a physical support for the vines to climb on.
Agronomic performances of biodegradable films as an alternative to polyethylene mulches in vineyards
The use of polyethylene (PE) mulch at planting ensures the successful and homogeneous establishment of vineyards and also leads them to produce one year earlier.
Alternatives to bunch thinning in yield control and its effects on quality of the grapes and wine composition in cv. Baga (Vitis vinifera L.)
Excessive yield and frequency of some diseases are strongly correlated, so yield control is an important current issue.
Anthocyanins, flavonols and flavanols of Vitis vinifera L. cv Syrah wines as affected by row orientation and ripeness levels
In this study results of the effect of different row orientations and ripeness levels on the wine chemical composition of Syrah (Vitis vinifera L.) are presented.
Berry size and maturity affect phenolic extraction into Pinot noir wines
Berry skin and seeds differ in their phenolic content, structure and accumulation dynamics during maturation. Therefore a change in berry size or maturity level may affect their contribution to wine composition.
Bunch exposure effects on the quality of Pinot noir and chardonnay fruit and base wines for cool climate sparkling wine production
Sparkling wine production in cool climates has particular focus on the composition of the phenolics present in the finished wine, however little is to be found in the literature as to how fruit can be manipulated to produce the desired result.
Consequences of leaf removal on canopy structure, yield and fruit composition of Touriga Nacional grapevines
Defoliation is one of the canopy management operations used as a technic to reduce the leaf area and, consequently, to contribute to improve production.
Effect of cluster thinning on wine quality of ‘Syrah’ vineyard submitted to double pruning management in Southeast Brazil
It is known that in temperate climates cluster thinning improves the quality of the wine. However, there are few studies available about this subject for the tropical vineyards in high altitude with double pruning technique.
Effect of early leaf removal on yield components, must composition and wine volatiles of Loureira cv. from north-west Spain
Yield management is a key technique in modern viticulture and is widely recognized as an important factor in the composition of resultant wines.
Effect of leaf removal on composition in Vitis vinifera L. cv. Tempranillo wine in Extremadura (Spain)
Early leaf removal is a management technique applied to regulate crop load and improve fruit microclimate conditions in vigorous vineyards, increasing aeration and sunlight exposure in the cluster zone.
Effect of nitrogen fertilization and water deficit on the quality of wines in relation to the biochemical composition of grapes of Vitis vinifera cv. Syrah
Nitrogen management and water status of grapevines are determining factors in wine quality.
Effect of picking date and several viticultural techniques on the rotundone concentration of Duras wines
Rotundone is a very potent aromatic compound, identified for the first time in 2008, in Shiraz wines by an Australian research team. There are still few very studies on this impact molecule, responsible for heavy peppery notes in wines.
Effects of timing and intensity of basal leaf removal in cv. Sauvignon
Leaf removal has been the subject of several studies, many of them in order to know the best time and intensity in order to promote yield and quality of the grapes.
