Relationships among Gene Expression and Anthocyanin Composition of Malbec Grapevine Clones
(2014-07)Anthocyanin profiles are commonly used for grapevine cultivar identification because it is currently accepted that this trait is closely related to their genetic characteristics. Nevertheless, the extent of the variation ... -
Expression of grapevine AINTEGUMENTA-like genes is associated with variation in ovary and berry size
(2016-05)Fruit size is a highly important trait for most fruit and vegetable crops. This trait has been a main selection target and could be involved in divergent selection processes leading to the differentiation between modern ... -

Coberturas vegetales en viñedos bajo riego localizado, respuesta fisiológica de especies herbáceas nativas a diferentes ambientes
(Escuela para Graduados, Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2015)En Mendoza, Argentina es imprescindible regar los cultivos debido a las escasas precipitaciones y a la elevada evapotranspiración. El uso de coberturas vegetales es una herramienta sostenible con múltiples beneficios ... -
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 ... -
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 ... -
Influence of fruit maturity, maceration length, and Ethanol amount on chemical and sensory properties of Merlot wines
(2013-12)Selected winemaking conditions were applied to fruit with ~20.3 and ~24.9 Brix over two seasons. Merlot grapes were harvested 33 (2011) and 34 (2012) days apart. At each harvest, half of the must was adjusted to emulate ... -
Regulated Deficit Irrigation Alters Anthocyanins, Tannins and Sensory Properties of Cabernet Sauvignon Grapes and Wines
(2015-04)Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard ... -
Sensory Impact of Extended Maceration and Regulated Deficit Irrigation on Washington State Cabernet Sauvignon Wines
(2013-12)Irrigation practices such as regulated deficit irrigation (RDI) and winemaking practices such as extended maceration have been experimentally evaluated from a chemical perspective but their impacts on sensory composition ... -
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 ... -
Yeast population dynamics during prefermentative cold soak of Cabernet Sauvignon and Malbec wines
(2015-04)Prefermentative cold soak is a widely used technique in red wine production, but the impact on the development of native yeast species is hardly described. The aim of this work was to analyse the dynamics and diversity of ... -
Relation between coumarate decarboxylase and vinylphenol reductase activity with regard to the production of volatile phenols by native Dekkera bruxellensis strains under ‘wine-like’ conditions
(2015-08)Dekkera/Brettanomyces bruxellensis is considered a major cause of wine spoilage, and 4-ethylphenol and 4-ethylguaiacol are the most abundant off-aromas produced by this species. They are produced by decarboxylation of the ... -
Extraction, Evolution, and Sensory Impact of Phenolic Compounds During Red Wine Maceration
