Armenia: historical origin of domesticated grapevine

Yeasts serve as highly versatile tools in oenology. They do more than just perform alcoholic fermentation. Nowadays, yeasts from various species, naturally present in grapes, are selected for specific non-fermentative applications. For example, the use of selected non-saccharomyces at the early stage of winemaking has become a common practice to limit the growth of unwanted microorganisms. When inactivated, yeasts can be fractionated into soluble and insoluble fractions providing a wide range of benefits related to structural components or specific metabolites.

Chitosan has been shown to enhance grapevine tolerance toward downy mildew while reducing the environmental impact of traditional protection products.

The objective of this study is to assess the potential for integrating sustainability guidelines into Geographical Indications of wine, especially in the case of the Denomination of Origin Campos de Cima da Serra (CCS), Brazil.

The production of table grapes in Chile is of great importance, being one of the main established fruit crops with over 43,000 hectares distributed across a diverse climate range, from the southern limit of the Atacama desert to the mediterranean zone. Chile is also one of the leading exporters of table grapes. producers must confront the challenges posed by the climate crisis, such as decreased rainfall, increased heatwaves, and extreme temperature events during the growing season, mainly associated with desertification in northern Chile (Atacama and Coquimbo regions).

Today’s viticulture is facing a new climatic scenario with temperature increases and rainfall deficits, generated by the effect of climate change. As a result of these new conditions, there are earlier harvests, increased plant water stress and higher disease risk in wetter wine-growing regions.
