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

Colloidal stabilization of young red wine by Acacia Senegal gum: the major implication of protein-rich arabinogalactan-proteins

Acacia senegal gum (Asen) is an edible dried gummy exudate [1] added in young red wines to ensure their colloidal stability, precluding the precipitation of the coloring matter. Asen macromolecules, belonging to the arabinogalactan-protein (AGP) family [2], are hyperbranched, charged and amphiphilic heteropolysaccharides composed especially of sugars (92-96 %) and a small fraction of proteins (1-3 %). Asen is defined as a continuum of macromolecules that could be separated into three fractions by hydrophobic interaction chromatography (HIC) [3-4]. HIC-F1 (85-94 % of Asen), HIC-F2 (6-18 % of Asen) and HIC-F3 (1-3 % of Asen) are named and classified in that order according to their protein content, and then a growing hydrophobicity. The efficiency of Asen towards the coloring matter instability is evaluated according to an “efficacy test” that consists to determine the Asen quantity required to prevent the flocculation by calcium of a colloidal iron hexacyanoferrate solution (International Oenological Codex).

Impact of glutathione-rich inactivated yeast on wine chemical diversity

Glutathione-rich inactivated dry yeasts (GSH-IDY) are claimed to accumulate intracellularly and then release glutathione in the must.

Ceramic imprint in wine: influence of hydraulic ratio on ceramic dissolution and wine pH in amphorae systems

This interaction is primarily due to an acidic attack on the ceramic by the wine. It results in (1) the dissolution of the ceramic into the wine and the release of a wide variety of elements; and (2) an increase of the wine pH. The extent of these effects depends on the mineralogical and chemical composition of the ceramic, as well as the hydraulic ratio of the ceramic-wine system (the term hydraulic ratio (ρ) defines here the volume of wine over the surface area of the ceramic in contact with the wine).

Microwave treatment of grapes: effect on the must and red wine polysaccharide composition

AIM: The application of microwaves (MW) to the grape is a technique to reduce the contact time with pomace because it allows to break the cell walls of the berry.

Promoting sustainability in Mediterranean agriculture: insights from the Portuguese vine & wine sector

Agroecology is an integrated approach that simultaneously applies ecological and social concepts and principles to redesign and manage food and agricultural systems, promoting agroecosystems with the necessary biological, socio-economic, and institutional diversity and alignment to support greater efficiency. Thus, several studies have been carried out at promoting the adoption of more agroecological practices among farmers and a wider audience concerning soil conservation and health maintenance.
