Estudio comparativo del potencial enológico de dos varietales tintos cultivados en la isla de Tenerife

Biodiversity loss in agrosystems is partly due to landscape simplification (field enlargement, hedgerows removal…) that led to a loss of heterogeneity of the overall landscape.

Climate plays a predominant role in vines’ growth and productivity and several environmental variables are already known to pose challenges to grapevine production and the horticultural industry as a whole. In this context, a number of extreme weather events already occurring and expected to occur in the next decades even more frequently and with higher magnitude results from current climate change scenario. The aim of this study was to examine the physiological responses of roots, leaves, and berries of Vitis vinifera cv. Sauvignon blanc to consecutive and combined stressors simulated in a semi-controlled environment.

Vitis vinifera L., is considered one of the world’s most important cultivated fruit crops. In agriculture, bunch morphology is a grapevine-specific trait, which directly impacts fruit quality and health.
Bunch size, shape, and compactness are major aspects of bunch morphology, with the degree of compactness emerging as an important trait for grapevine genetic enhancement and vineyard management. The importance of this trait stems from its impact on disease susceptibility, berry ripening, and other grape quality properties. However, current knowledge of the genes controlling it remains limited.

A 3-year zoning study promoted by the Cooperative Winery Valpolicella (Negrar, Verona, Italy) was carried out on a wine territory of about 500 ha.

Light is a fundamental part at sales points which influences in the conservation of wines, particularly in those that are sold in transparent glass bottles such as rosé wines and increasingly white wines. The photochemical effect known as “light-struck taste” can cause changes in the aromatic characteristics of the wine. This “light-struck taste” is due to reactions triggered by the photochemical sensitivity of riboflavin (RBF).
