Application of vine-shoot chips during winemaking and aging of Malbec and Bonarda wines
(MDPI Publication, 2021-07)The growing demand in recent years for sustainable wine production has led to the management of waste and by-products. Among them, vine-shoots could be used as additives comparable to the oak fragments widely employed in ... -
Biodiversity of Aspergillus section Nigri populations in Argentinian vineyards and ochratoxin A contamination
(2013-12)Aspergillus section Nigri are described as the main source of ochratoxin A (OTA) contamination in grapes and wine worldwide. The knowledge of the factors affecting grape contamination by species included in this section ... -
Characterization of the phenolic fraction from Argentine wine and its effect on viability and polysaccharide production of Pediococcus pentosaceus
(2015-12)Objectives: To qualitatively and quantitatively characterize a low molecular weight phenolic fraction (LMF) of Malbec wine from Cafayate, Argentina, and evaluate its effect on viability and exopolysaccharide production of ... -
Characterization, antibacterial and biological activities of phenolic fraction of argentinean red wines
(Bentham Open, 2014-09)For the first time, the qualitative and quantitative characterization of phenolic compounds of lower molecular weight fraction (LMF) were evaluated in commercial Cabernet Sauvignon (CS) and Tannat (T) wines varieties ... -
Chemical and chromatic effects of fermentation temperature on three clones of Pinot noir over two consecutive vintages
(American Society for Enology and Viticulture (ASEV), 2022-10-14)Three different Pinot noir clones (115, 777, and 828) from the Central Coast of California were subjected to different maceration temperature regimes for 14 days using triplicate fermentations (Cold: 10°C; Hot: 25°C; and ... -
Chemical and sensory effects of cold soak, whole cluster fermentation, and stem additions in Pinot noir wines
(American Society for Enology and Viticulture, 2019-01)Pinot noir wines were produced over two consecutive vintages using four and six different winemaking techniques in 2014 and 2015, respectively. In addition to control wines, the separate and combined effect of cold soak ... -
Chemical, chromatic, and sensory attributes of 6 red wines produced with prefermentative cold soak
(2015-05-01)Six red grape cultivars, Barbera D’Asti, Cabernet Sauvignon, Malbec, Merlot, Pinot Noir and Syrah, were produced with or without prefermentative cold soak (CS). Cold soak had no effect on the basic chemical composition of ... -
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 ... -
Combination of pre-fermentative and fermentative strategies to produce Malbec wines of lower alcohol and pH, with high chemical and sensory quality
(International Viticulture and Enology Society (IVES), 2020)The climatic conditions in some wine regions imply in many cases the important delay in the harvest date to achieve an appropriate phenolic maturity in red grape varieties, leading to wines with high pH and alcohol content. ... -
Combined effect of prefermentative cold soak and SO2 additions in Barbera D’Asti and Malbec wines : anthocyanin composition, chromatic and sensory properties
(2016)The effects of prefermentative cold soak (CS) combined with two SO2 additions (50 and 100 mg L1) on the anthocyanin composition, chromatic properties and sensory attributes of Barbera D'Asti and Malbec wines were studied. ... -
Combined effect of temperature and ammonium addition on fermentation profile and volatile aroma composition of Torrontés Riojano wines
(2018-01)The effects of process temperature and ammonium supplementation on fermentation profile, volatile aroma composition and wine sensory characteristics were evaluated in Torrontés Riojano (Vitis vinifera L.) wines from Mendoza ... -
Construction of low-ethanol-wine yeasts through partial deletion of the Saccharomyces cerevisiae PDC2 gene
(2017)We propose an alternative GMO based strategy to obtain Saccharomyces cerevisiae mutant strains with a slight reduction in their ability to produce ethanol, but with a moderate impact on the yeast metabolism. Through ... -
Efecto de la técnica de sangrado sobre la composición fenólica de vinos cv. Malbec = Effect of saignée on phenolic composition of Malbec wines
(Universidad Nacional de Cuyo. Facultad de Ciencias Agrarias, 2013)El mercado actual exige, en gran parte, la disponibilidad de vinos estructurados con coloraciones intensas, razón por la cual los enólogos evalúan constantemente diversas variantes tecnológicas tendientes a satisfacer los ... -
Effect of different closure types and storage temperatures on the color and sensory characteristics development of Argentinian Torrontes Riojano white wines aged in bottles
(Elsevier, 2021-06)During aging, most bottled white wines lose their distinctive organoleptic characteristics according to their storage conditions (closure, temperature, time). However, the effect of these factors on organoleptic characteristics ... -
Effect of extended maceration and ethanol concentration on the extraction and evolution of phenolics, colour components and sensory attributes of Merlot wines
(Wiley, 2013-02)Background and Aims: Anecdotal evidence suggests that there may be a synergistic effect of ethanol (EtOH ) and prolonged skin contact on the extraction of certain phenolics that may negatively impact wine sensory properties. ... -
Effect of leaf‐to‐fruit ratios on phenolic and sensory profiles of Malbec wines from single high‐wire‐trellised vineyards
(Wiley, 2020-08)BACKGROUND: The single high‐wire system is a free canopy trellis system suitable for warm to hot climates. In a global warming scenario, it arouses as a technological solution since it prevents berry overheating and sunburn. ... -
