ABA and GA 3 increase carbon allocation in different organs of grapevine plants by inducing accumulation of non-structural carbohydrates in leaves, enhancement of phloem area and expression of sugar transporters
(2016)Grape quality for winemaking depends on sugar accumulation and metabolism in berries. Abscisic acid (ABA) and gibberellins (GAs) have been reported to control sugar allocation in economically important crops, although the ... -
Co-fermentation of Syrah with various additions of Viognier: Effect on colour and phenolics during winemaking and bottle ageing
(2013-10)The impetus for the study described in this article was to assess the effect of co-fermentation of Syrah and Viognier in the phenolic chemistry and colour stability of the resulting wines and to document potential benefits ... -
Culture-dependent and independent techniques applied to monitor yeast species on cold soak at different temperatures in winemaking
(2016)Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance flavor ... -
Effect of non-wine Saccharomyces yeasts and bottle aging on the release and generation of aromas in semi-synthetic Tempranillo wines
(Elsevier, 2022-03)Interest in the use of non-conventional yeasts in wine fermentation has been increased in the last years in the wine sector. The main objective of this manuscript was to explore the aromatic diversity produced by wild and ... -
Effect of transient thermal shocks on alcoholic fermentation performance
(Elsevier, 2019-10)Stuck and sluggish fermentations are among the main problems in winemaking industry leading to important economic losses. Several factors have been described as causes of stuck and sluggish fermentations, being exposure ... -
Elaboración de vinos caseros : primera parte
(2016)En la actualidad, hay información disponible sobre los procesos de elaboración de vinos a escalas industriales, con el uso de tecnologías y maquinarias poco accesibles para un elaborador casero. Con este escrito se busca ... -
Estimación de costos de producción de vid para vinificar para el Oasis Este de Mendoza
(EEA Junín, INTA, 2021-01)En el presente documento se determinan los costos operativos y costos totales de producción del cultivo de vid para vinificar varietales en espaldero tradicional y básicas en parral tradicional. -
Evaluación de clones de Pinot noir en la Norpatagonia
(EEA Alto Valle, INTA, 2023)En esta publicación se muestra el comportamiento regional de cuatro clones franceses e italianos de Pinot noir que fueron probados en el Norte de la Patagonia durante seis años. Se describe el manejo a campo, la vinificación ... -
Influencia de cuatro alternativas de crianza en roble sobre el color, la composición polifenológica y las características organolépticas de vinos Malbec y Cabernet Sauvignon
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2009-05)Los costos de las barricas, por el tipo de cambio en la Argentina, son inaccesibles para muchas bodegas. Debido a esto, muchas de ellas utilizan sistemas alternativos de crianza, no conociendo claramente las consecuencias ... -
Microoxigenacion controlada en vinos
(2016-07-20)La Microoxigenación controlada en vinos es una técnica que se desarrolló en Francia y consiste en incorporar pequeñas cantidades de oxígeno a los vinos, de manera de imitar el proceso que ocurre en la barrica. El Ing. Agr ... -
Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
(MDPI, 2019-01)Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ... -
Molecular and enological characterization of a natural Saccharomyces uvarum and Saccharomyces cerevisiae hybrid
(2015-07)Saccharomyces cerevisiae plays a main role in the winemaking process, although other species, like Saccharomyces uvarum or Saccharomyces paradoxus, have been associated with must fermentations. It has been reported in ... -
Monitoring of killer yeast populations in mixed cultures: influence of incubation temperature of microvinifications samples
(2012-11)Killer yeasts are frequently used to combat and prevent contamination by wild-type yeasts during wine production and they can even dominate the wine fermentation. Stuck and sluggish fermentations can be caused by an ... -
Pautas tecnológicas vid para vinificar: manejo y análisis económico financiero
(Ediciones INTA, 2007)Al igual que las anteriores publicaciones de la EEA Alto Valle: "Pautas Pepita", "Pautas Carozo" y "Pautas cerezo", el presente documento pretende ser orientador para profesionales y productores, así como una referencia ... -
Selection of non-Saccharomyces yeasts to be used in grape musts with high alcoholic potential: A strategy to obtain wine with reduced etanol content
(2017)Ethanol content of wine has increased over the last decades as consequence of searching phenolic maturity, requiring increased grape maturity. This may result in the production of wines with excessive alcohol levels ... -
Sensory and chemical effects of two alternatives of prefermentative cold soak in Malbec wines during winemaking and bottle ageing
(2015)Two alternatives of cold soak (CS), traditional external refrigeration (CS‐T) and use of solid CO2 (CS‐DI), were evaluated in Malbec wines and contrasted against a control (C) during winemaking and up to 24 months of bottle ... -
Tracing the origin of Argentine Malbec wines by sensometrics
(Springer Nature, 2024-02)The study of terroir, increasingly popular in scientific circles, remains a challenging field, particularly in terms of sensory analysis. This paper summarizes our own contribution to the field—an approach for tracing the ... -
