Exploring diversity of grapevine responses to Flavescence dorée infection

Vitis vinifera L. is the main European grapevine species used for wine production. It is characterized by the production of grapes and wines with unique organoleptic properties, distinguished by high quality and the absence of strong “foxy” aromas.

In recent years there has been a growing demand for alternative packaging designs in the food industry focused on diminishing the carbon footprint. Despite the environmental advantages of cans versus bottles, the traditional environment of wine has hindered the establishment of less contaminant containers. In this context, the objective of this study was to understand and generate knowledge about consumers´ perception of canned wines in comparison to bottled wines.

For characterization, sensory designing and authentication rapid analytical technologies have become available. Some, like Proton Transfer Reaction Mass Spectrometry allow a rapid spectrum of the volatile compounds of wines. Combined with chemometrics wines can be characterized. The same approach can be used to calculate the results of virtual mixtures and allow formulation of constant quality blends. Other new techniques and portable devices based on spectroscopy allow measurements on production sites and in grocery stores, even for the smart consumer. We will present some examples of the application of these techniques for authentication of wines, both in the laboratory and on site.

Cover crops in vineyards have been extensively studied, as the choice of grass species and their management significantly influence soil properties and vine performance.

Autochthonous varieties, called ‘criollas’, are highly cultivated in South America. For instance, in Peru or Chile they are used for making Pisco. In Argentina, they represent 33% of the grapevine cultivated area.
