Stomatal restrictions to photosynthesis in grapevine cultivars grown in a semiarid environment

The paper discusses potential implications of New Genomic Technologies (NGTs) on European Plant Variety and Wine Law.

Vineyards are highly variable and this variation is largely driven by environmental conditions and seasonal variation. For example, warm temperatures

The introduction into the Italian wine supply chain of the latest generation of fungi-resistant grapevine varieties, endowed with a greater or lesser strong resistance to downy and powdery mildews, represents a valid tool of making viticulture more sustainable, particularly in northern regions of the peninsula, where climatic conditions accentuate the pressure of fungal diseases. However, the affirmation of resistant varieties is a function of their agronomic value, as well as of their oenological and sensorial value. The purpose of this study was to evaluate in detail the sensory potential of the new resistant varieties, in order to understand their real possibility of inclusion in the modern global enological context.

The wine industry is currently shifting toward more sustainable production systems. There are many reasons for this as the interest of people over climate change and, consequently the wine consumer’s choice toward organic and biodynamic, reduced carbon-footprint, vegan and other environmentally friendly wines. While the viticultural effects of biodynamic and organic practices on wine grapes have been investigated, there is a lack in literature on the general effect on the final quality of wine

The actual demand by consumers for safer and healthier food and beverage is pushing the wine sector to find alternative methods to avoid the use of sulphur dioxide in winemaking. Ozone is already used in the wine industry to produce sulphur dioxide-free wines through the patented method Purovino®.
