The key role of vineyard parcel in modifying flavor compounds of Cabernet Sauvignon grapes

The USDAAgricultural Research Service maintains Vitis germplasm repositories in Geneva, NY and Davis, CAcollectively preserving approximately 5,000 unique accessions representing 30 Vitis species.

In the old-world viticulture, there is a common but most often not scientifically proved consideration that supplemental irrigation should detrimentally affect berry and wine composition. In the semi-arid

The use of new fungus disease-tolerant varieties is a promising long-term solution to better manage chemical input in viticulture, but unfortunately little is known regarding these new hybrids fruit development and metabolites accumulation in front of abiotic stresses such as water deficit (WD). Thus, prior to the adoption of such varieties by the wine industry in Mediterranean regions, there is a need to consider their suitability to WD.

Phenolic compounds play a key role in wine sensory properties, traditionally associated with colour, taste attributes (e.g., bitterness) and trigeminal sensations such as astringency.

Table grape consumption worldwide has experienced a remarkable growth in the first two decades of the 21st century, becoming the third most consumed fresh fruit in some countries, after bananas and apples. This increase has been attributed to several reasons, including the availability of seedless grapes, which has been a key factor in the increase in consumption.
