Interactions between Saccharomyces and Oenococcus oeni strains from Amarone wine affect malolactic fer- mentation and wine composition
Introduction: The term malolactic fermentation (MLF) indicates a range of metabolic reactions by strains of lactic acid bacteria, usually Oenococcus oeni. MLF influences the organoleptic traits of wine and is necessary for the aging of red wines and certain white wines (LONVAUD-FUNEL 1999). However, the activities of malolactic bacteria (MB) in wine are affected by numerous factors, among which...
متن کاملCore Microbiota and Metabolome of Vitis vinifera L. cv. Corvina Grapes and Musts
The composition and changes of the fungal population and of the metabolites present in grapes and in ferments of Vitis vinifera L. cv. Corvina, one of the major components of the Amarone musts, were dissected aiming at the identification of constant characteristics possibly influenced by the productive process. The fungal populations and metabolomic profiles were analyzed in three different vin...
متن کاملNorisoprenoids, Sesquiterpenes and Terpenoids Content of Valpolicella Wines During Aging: Investigating Aroma Potential in Relationship to Evolution of Tobacco and Balsamic Aroma in Aged Wine
During wine aging, tobacco and balsamic aroma notes appear. In this paper, volatile compounds directly or potentially related to those aromas have been investigated in Corvina and Corvinone wines during aging. Corvina and Corvinone are two northern-Italy autochthonous red grape varieties, used to produce Valpolicella Classico and Amarone wines, both characterized by tobacco and balsamic aroma n...
متن کاملEditorial: Microbiota of Grapes: Positive and Negative Role on Wine Quality
During the vinification process, we can generally separate four main phases associated with specific microbial dominances: (i) first stages of alcoholic fermentation (AF) (non-Saccharomyces), (ii) most part of AF, up to the end (Saccharomyces), (iii) malolactic fermentation (MLF) (lactic acid bacteria or LAB), and (iv) undesired changes associated to microbial metabolism (spoilage yeasts and ba...
متن کاملWhole-Metagenome-Sequencing-Based Community Profiles of Vitis vinifera L. cv. Corvina Berries Withered in Two Post-harvest Conditions
Vitis vinifera L. cv. Corvina grape forms the basis for the production of unique wines, such as Amarone, whose distinctive sensory features are strongly linked to the post-harvest grape withering process. Indeed, this process increases sugar concentration and changes must characteristics. While microorganisms involved in must fermentation have been widely investigated, few data are available on...
