PIWIs’ variation in drought response under semi-controlled conditions 

This study examines how stepwise alcohol reduction using membrane-based processes affects the composition, aroma, and sensory properties of an Austrian Grüner Veltliner wine.

Downy mildew (Plasmopara viticola) and powdery mildew (Erysiphe necator) are among the most destructive diseases affecting grapevine (Vitis vinifera L.).

In recent years, the consumption of fine wines in Brazil has increased significantly, a phenomenon that is also reflected in the expansion of production to new regions. In the brazilian southeast for example, the so-called “winter wines” are being produced, through management in two cycles, one of formation and one of production, with two prunings and one harvest per year, a technique known as double pruning, with vineyards established at altitudes close to or above 1,000 m above sea level.

Crimson Seedless’ (Vitis vinifera L.) is a late-ripening, red seedless table grape cultivar with inadequate anthocyanin accumulation and less than ideal berry size issues

The terroir offers great variability in the typicity of the wines produced. Following tastings integrating several vintages, the multiple factor analysis of the sensory data revealed a group of taste criteria contributing to the notion of “Power”, referenced “Power and Harmony”, which makes it possible to differentiate wines from various terroirs of the Middle Loire Valley (Pages et al ., 1987).
