The Bergerac guaranteed vintage area « terroirs »

Abstract

The vineyard of Bergerac, a guaranteed vintage, is situated in the mid-Lot valley, which has siliceous terraced rows on its hillsides, and on its bordering plateaux, composed of limestone and clay of the tertiary geological eras. In order to study and do a cartography of the « terroirs » in the 91 rural districts which include the area concerned (a project commissioned by the locals and european authorities), we defined a scale comprising twelve criterions for differentiating the « terroirs »; this enabled us to describe and do a cartography of them on a scale of 1/10 000. This study comes within the scope of a regional politic of cartography of the « terroirs », to give a toll of recomposition of the guaranteed vintage in the south-west of France.

The role of vine trunk height in delaying grape ripening: insights for viticultural adaptation strategies

Global changes in temperature patterns necessitate the development of viticultural adaptation strategies. One promising approach involves modifying the training system and elevating trunk height. This study explored the potential of raising the vine trunk as an adaptive strategy to counteract the effects of increasing temperatures and delay ripening. Thermal conditions, radiation levels, and must composition were measured at different heights (10 and 150 cm) in a commercial vineyard of the minority variety Maturana Blanca, trained on a vertical cordon.

Relationship between terroir and acidity for the red wine grape cultivar Malbec N or Cot N (Vitis vinifera L.) in AOC “Cahors” and “Côtes du Frontonnais “

L’étude préliminaire, réalisée sur les principaux cépages de la région Midi-Pyrénées, a montré que le Cot N possédait des teneurs en acide tartrique dans les moûts et les vins plus élevées que celles des cépages Négrette N, Tannat N, Duras N et Fer Servadou N.

Castilla y León is the third longest region in the European Union, having more than 85.000 vineyard hectares.

Capture depletion of grapevine DNA: an approach to advance the study of microbial community in wine

The use of next-generation sequencing (NGS) has helped understand microbial genetics in oenology. Current studies mainly focus on barcoded amplicon NGS but not shotgun sequencing, which is useful for functional analyses. Since the high percentage of grapevine DNA conceals the microbial DNA in must, the majority of sequencing data is wasted in bioinformatic analyses. Here we present capture depletion of grapevine whole genome DNA.

A sundial vineyard: impact of row density and orientation on cv. Cabernet-Sauvignon physiology and grape composition, insights to face a climate change scenario

An experimental vineyard with a radial array was planted in 2018, to provide valuable information on the relationship between orientation and planting density on plant physiology and cluster microclimate, and the consequent impacts on grape secondary metabolites, including aromas and polyphenols.
