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 different concentrations of bioslurry on the germination and production of tomato seedlings (Solanum lycopersicum L.) = Efecto de diferentes concentraciones de biol en la germinación y producción de plantines de tomate (Solanum lycopersicum L.)
(Facultad Nacional de Agronomía Medellín, Universidad Nacional de Colombia, 2023-01)El tomate es uno de los principales productos hortícolas en la Argentina. Su cultivo es intensivo en el uso de fertilizantes y pesticidas, que impactan negativamente al ambiente. Los fertilizantes químicos de uso habitual ... -
Effect of elevated temperature on the onset and rate of mesocarp cell death in berries of Shiraz and Chardonnay and its relationship with berry shrivel
(Wiley, 2013-02)Background and Aim: Berry water loss at late stages of ripening is a cultivar dependent‐trait correlated with mesocarp cell death. We tested the hypothesis that elevated temperature anticipates the onset and increases the ... -
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. ... -
Effect of low temperature fermentation on the yeast-derived volatile aroma composition and sensory profile in Merlot wines
(Elsevier, 2021-02)Different winemaking practices have been tried to improve wine quality and differentiate wine styles. Low temperature fermentation has been proposed to enhance the aroma profile in young red wines. The aim of this work was ... -
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 ... -
Effects of maceration length after prefermentative cold soak: Detailed chromatic, phenolic and sensory composition of cabernet sauvignon, malbec and merlot wines
(Elsevier, 2021-09-21)Cabernet Sauvignon, Malbec and Merlot grapes were processed with prefermentative cold soak (CS) for 5 days followed by a short maceration time of 5 days (CS + 5d), or a long maceration time of 10 days (CS + 10d). CS did ... -
