Contribution to the sensory and volatile characterization of four traditional Galician red varieties

Abstract

Galicia, a region sited in the northwest of Spain, is one of the most important wine production area, with five Appellations of Origin Controlled (AOC). In the last few years, there is a growing interest within the Galician winemaking industry in the recuperation of the denominated traditional or noble varieties, in order to endow differentiated and singular characteristics to the Galician red and white wines. Caiño is the name of some minor red Vitis grown in this region. This general name involves a group of red autochthonous cultivars, including Caiño Redondo, Caiño da Terra, Caiño Longo and Caiño Astureses, each of them with different characteristics.
The quality of these grapes is appreciated in winemaking but the majority of Caiño wines are elaborated blended with other varieties of Galician grapes (Mencia, Souson, Garnacha), because pure red Caiño wines present a high acidity that requires blending to balance them. Considerable research and development on the viticulture and enology of these varieties are still necessary, in particular in relation to the chemical aroma composition and the sensory properties of the corresponding wines.
In the present communication we contribute with the study of the aroma composition to a better understanding of the wines obtained exclusively from the four cultivars with the name Caiño. The other aim of this study was to establish the aromatic profile, in terms of attributes, that identifies the aroma of young wines from Caiño Redondo, Caiño da Terra, Caiño Longo and Caiño Astureses cultivars

Multispectral data from Sentinel-2 as a tool for monitoring late frost events on vineyards

Aim: Climate change is altering some aspects of winegrape production with an advancement of phenological stages which may endanger viticultural areas in the event of a late frost. This study aims to evaluate the potential of satellite-based remote sensing to assess the damage and the recovery time after late frost events.

PHOTO OXIDATION OF LUGANA WINES: INFLUENCE OF YEASTS AND RESIDUAL NITROGEN ON VSCS PROFILE

Lugana wines are made from Turbiana grapes. In recent times, many white and rosé wines are bottled and stored in flint glass bottles because of commercial appeal. However, this practice could worsen the aroma profile of the wine, especially as regards the development of volatile sulfur compounds (VSCs). This study aims to investigate the consequences of exposure to light in flint bottles on VSCs profile of Lugana wines fermented with two different yeasts and with different post-fermentation residual nitrogen.

Model-assisted analysis of the root traits underlying RSA genotypic diversity in Vitis: a promising approach for rootstock selection?

By dissecting the root system architecture (RSA) into its underpinning components (e.g. root emission, axial growth, radial growth, branching, root direction or tropism) and identifying the relationships between them, functional-structural 3D root models are promising tools for analyzing the diversity and complexity of root system phenotypes with Genotype × Environment interactions. The model parameters are assumed to be synthetic traits, less influenced by the environment, and consequently with less polygenic architectures than the integrative RSA traits they drive. Root models can serve as a basis for in silico development of root system ideotypes by highlighting the developmental processes and parameters that most likely influence RSA fitness.
