Optimization of fermentation-relevant factors: A strategy to reduce ethanol in red wine by sequential culture of native yeasts
(2018-08-14)Current consumer preferences are determined by well-structured, full-bodied wines with a rich flavor and with reduced alcohol levels. One of the strategies for obtaining wines with reduced ethanol content is sequential ... -
Probabilistic model for the spoilage wine yeast Dekkera bruxellensis as a function of pH, ethanol and free SO2 using time as a dummy variable
(Elsevier, 2014-01-17)The present study uses a probabilistic model to determine the growth/no growth interfaces of the spoilage wine yeast Dekkera bruxellensis CH29 as a function of ethanol (10–15%, v/v), pH (3.4–4.0) and free SO2 (0–50 mg/l) ... -
Reduction of Zygosaccharomyces rouxii Population in Concentrated Grape Juices by Thermal Pasteurization and Hydrostatic High Pressure Processing
(Springer, 2019-02)Zygosaccharomyces rouxii is the most frequent spoilage yeast species detected in concentrated grape juice. In order to reduce Z. rouxii populations and consequently extend the microbiological shelf life of this product, ... -
Selection of indigenous Saccharomyces cerevisiae strains to ferment red musts at low temperature
(2012-03)The aim of this work was to select native Saccharomyces cerevisiae strains to conduct the alcoholic fermentation of red must at low temperature (15°C), thus producing volatile compounds that enhance the aromatic profile ... -
Selection of Native Non-Saccharomyces Yeasts with Biocontrol Activity against Spoilage Yeasts in Order to Produce Healthy Regional Wines
(MDPI, 2019-07)Two major spoilage yeasts in the wine industry, Brettanomyces bruxellensis and Zygosaccharomyces rouxii, produce off-flavors and gas, causing considerable economic losses. Traditionally, SO2 has been used in winemaking to ... -
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 ... -
Vino bretado: ¿complejo o defectuoso? Límite entre su aceptación y su rechazo desde una perspectiva de gestión de la calidad
(Universidad Juan Agustin Maza, 2022-11-11)Una alteración particular de vinos es causada por levaduras del género Brettanomyces, defecto conocido como «bretado» o «brett», el cual se percibe tanto como un atributo positivo o negativo, dependiendo de los niveles de ... -
Yeast identification in grape juice concentrates from Argentina
(Wiley, 2008-02)Aims: The purpose of this study was to identify yeast species present in spoiled and unspoiled grape juice concentrates from Argentine industries. Methods and Results: Osmophilic and osmotolerant yeasts were isolated from ... -
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 ...
