Varietalidad y etiquetado: Porcentaje mínimo de cortes de vinos wine varietals and labelling

Abstract: Se evaluaron 95 vinos experimentales, cosecha 2016, tanto en su estado puro (100%) como a distintos porcentajes de combinación (90; 85; 80; 75; 60%), con el fin determinar el porcentaje mínimo de una variedad que debe tenerse en cuenta en un corte de vino etiquetado como “variedad única”. Los respectivos cortes de las variedades bajo estudio (Malbec, Cabernet Sauvignon, Bonarda, Syrah, Merlot, Tempranillo, y Aspirant Bouchet) fueron supeditados al Análisis Descriptivo Cualitativo (se evaluaron 6 atributos olfa… Show more

“…Varietal wines are wines made from a single grape variety or at least 80 % of a single variety, as defined in the European Union (Salvador Insua, 2016), although in some countries such as Argentina, a minimum of 85 % is required (Murgo et al, 2019). In these wines, which constitute complex systems due to the presence of multiple chemical and enzymatic species, thiols are very sensitive to oxidation reactions that could generate a variety of products, among which those resulting from their nucleophilic addition to (+)-catechin-(o-quinone) and dimeric disulphides have been proposed (see Figure 4).…”
