The influence of climate on the grapevine phenology and content of sugar and total acids in the must

Emerging from anthropology, climatology, ecology, gastronomy, geography and wine tourism, terroir tourism has been recently recognized to have potential for developing rural agriculture tourism

Over the last few years, several tools have been developed to reduce the quantity of sulfites used during winemaking, including bioprotection. Although its effectiveness in preventing the development of spoilage microorganisms has been proven, few data are available on the impact of sulfite substitution by bioprotection on the final product. The objective of this study was therefore to characterize Chardonnay wines with the addition of sulfite or bioprotection in the pre-fermentation stage. The effects of both treatments on resulting matrices was evaluated at several scales: analysis of classical oenological parameters, antioxidant capacity, phenolic compounds, non-volatile metabolome and sensory profile.

Agricultural productivity must promote management systems that incorporate sustainability principles, and viticulture is no exception.

Sun exposure is needed for balanced grape ripening and sugar accumulation but is also one of the main drivers for a premature Riesling ageing
