Combination of pre-fermentative and fermentative strategies to produce Malbec wines of lower alcohol and pH, with high chemical and sensory quality
Fanzone, Martín Leandro; Sari, Santiago Eduardo; Mestre Furlani, Maria Victoria; Catania, Anibal Alejandro; Catelén, María J.; Jofre, Viviana Patricia; González-Miret, María Lourdes; Combina, Mariana; Vazquez, Fabio; Maturano, Yolanda Paola (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. ... -
Culture-dependent and independent techniques applied to monitor yeast species on cold soak at different temperatures in winemaking
Maturano, Yolanda Paola; Mestre Furlani, Maria Victoria; Combina, Mariana; Toro, Maria Eugenia; Vazquez, Fabio; Esteve Zarzoso, Braulio (2016)Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance flavor ... -
Enzymatic activities produced by mixed Saccharomyces and non-Saccharomyces cultures : relationship with wine volatile composition
Maturano, Yolanda Paola; Assof, Mariela Vanesa; Fabani, Maria Paula; Nally, María Cristina; Jofre, Viviana Patricia; Rodriguez Assaf, Leticia Anahi; Toro, Maria Eugenia; Vazquez, Fabio; Castellanos de Figueroa, Lucía Inés (2015-11)During certain wine fermentation processes, yeasts, and mainly non-Saccharomyces strains, produce and secrete enzymes such as b-glucosidases, proteases, pectinases, xylanases and amylases. The effects of enzyme activity ... -
Evaluation of behaviour of Lachancea thermotolerans biocontrol agents on grape fermentations
Nally, Maria Cristina; Ponsone, María Lorena; Pesce, Virginia Mercedes; Toro, Maria Eugenia; Chulze, Sofia Noemí (Society for Applied Microbiology, 2018-07)Previous researches have showed that Lachancea thermotolerans strains RCKT4 and RCKT5 inhibited the growth of Aspergillus. However, currently, there are no data on their nutritional preferences, as a possible substrate ... -
Free Volatile Compounds of cv. Pedro Giménez (Vitis vinifera L.) White Grape Must Grown in San Juan, Argentina
Maturano, Yolanda Paola; Nally, María Cristina; Assof, Mariela Vanesa; Toro, Maria Eugenia; Castellanos de Figueroa, Lucía Inés; Jofre, Viviana Patricia; Vazquez, Fabio (2018)The free aromatic composition of must from Pedro Giménez grapes, grown in San Juan, Argentina, was characterised. Samples from the vintages of 2008 and 2009 were analysed by gas chromatography–mass spectrometry–solid phase ... -
Impact on Sensory and Aromatic Profile of Low Ethanol Malbec Wines Fermented by Sequential Culture of Hanseniaspora uvarum and Saccharomyces cerevisiae Native Yeasts
Mestre Furlani, Maria Victoria; Maturano, Yolanda Paola; Gallardo, Candelaria; Combina, Mariana; Mercado, Laura Analia; Toro, Maria Eugenia; Carrau, Francisco; Vazquez, Fabio; Dellacassa, Eduardo (MDPI, 2019-07)It is well known that high ethanol levels in wines adversely affect the perception of new wine consumers. Moreover, numerous issues, such as civil restrictions, health risk and trade barriers, are associated with high ... -
Monitoring of killer yeast populations in mixed cultures: influence of incubation temperature of microvinifications samples
Maturano, Yolanda Paola; Nally, María Cristina; Toro, María Eugenia; Castellanos de Figueroa, Lucía Inés; Combina, Mariana; Vazquez, Fabio (2012-11)Killer yeasts are frequently used to combat and prevent contamination by wild-type yeasts during wine production and they can even dominate the wine fermentation. Stuck and sluggish fermentations can be caused by an ... -
