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 ... -
Generation of a non-transgenic genetically improved yeast strain for wine production from nitrogen-deficient musts
(MDPI, 2020)The yeast Saccharomyces cerevisiae is the main species responsible for the process that involves the transformation of grape must into wine, with the initial nitrogen in the grape must being vital for it. One of the main ... -
Generation of intra- and interspecific Saccharomyces hybrids with improved oenological and aromatic properties
(Wiley, 2022-04)Non-wine yeasts could enhance the aroma and organoleptic profile of wines. However, compared to wine strains, they have specific intolerances to winemaking conditions. To solve this problem, we generated intra- and ... -
Genomic and phenotypic comparison between similar wine yeast strains of Saccharomyces cerevisiae from different geographic origins
(Wiley, 2010-05)Aims: To study genomic and phenotypic changes in wine yeasts produced in short time periods analysing yeast strains possibly derived from commercial strains recently dispersed. Methods and Results: We conducted a genomic ... -
Hybridization and spore dissection of native wine yeasts for improvement of ethanol resistance and osmotolerance
(Springer, 2022-09)Global warming has a significant impact on different viticultural parameters, including grape maturation. An increment of photosynthetic activity generates a rapid accumulation of sugars in the berry, followed by a dehydration ... -
Screening of Saccharomyces strains for the capacity to produce desirable fermentative compounds under the influence of different nitrogen sources in synthetic wine fermentations
(Elsevier, 2021-02)A collection of 33 Saccharomyces yeasts were used for wine fermentation with a sole nitrogen source: ammonium and four individual aroma-inducing amino acids. The fermentation performance and chemical wine composition were ... -
Simultaneous Inoculation of Malbec (Vitis vinifera) Musts with Yeast and Bacteria: Effects on Fermentation Performance, Sensory and Sanitary Attributes of Wines
(Faculty of Food Technology and Biotechnology, University of Zagreb (Croacia), 2009)Malolactic fermentation has important consequences for the quality of wine. The present study analyzes the effect of timing of inoculation with bacteria on the performance of alcoholic and malolactic fermentation in Malbec ...
