The Bergerac guaranteed vintage area « terroirs »

REVINE is a 3 year European projected funded by PRIMA programme which proposes the adoption of regenerative agriculture practices with an innovative and original perspective, in order to improve the resilience of vineyards to climate change in the Mediterranean area. Regenerative agriculture ameliorates soil structure and microbial biodiversity that, in turn, leads to crop resilience against biotic and abiotic stressful factors. Moreover, enrichment of beneficial microbes in the rhizosphere, such as PGPR and PGPF, are known to trigger the plant immunity inducing the priming state.

The concept of viticultural terroir includes soil, sub-soil, and climatic factors but also many management viticultural and oenological practices which are chosen according to know-how of the winegrowers.

AIM: High pressure technologies represent a promising alternative to thermal treatments for improving quality and safety of liquid foods.

The conventional wisdom of vintners is that alkalinity, and thus less sour and more rounded taste, are enhanced in wine and grapes challenged by low-nutrient soils.

The overall quality of fine wines is linked to the development of “bouquet” during wine bottle ageing1. Several chemical reactions, occurring in atmosphere protected from oxygen, are favourable to the formation and preservation of sulphur compounds such as dimethyl sulfide (DMS). DMS accumulate in wines thanks to hydrolysis of its precursors (DMSp) mainly constituted by S-
