The potential of chitosans to control grapevine trunk diseases (GTDs) has been studied in a public-private partnership. In vitro tests, vineyard efficacy trials and laboratory analyses were carried out to understand their mode of action. In vitro, low molecular weight (MW) chitosans, the most soluble, were often the most effective. In the vineyard, the most effective were those with a medium MW, in particular chitosan hydrochlorides which form a protective film. They could be used to dress wounds caused by pruning, re-trunking or curettage.

Ensuring wine quality is crucial. However, the rise in quercetin deposits in red wines, particularly those made from Sangiovese grapes, is escalating due to factors such as machine harvesting and climate change (Price et al., 1995; Blancquaert et al., 2019; Gambuti et al., 2020; Vendramin et al., 2022). This issue extends beyond mere visual inconveniences linked to bottled wine to concerns about potential organoleptic damage. Currently used methods, such as PVPP fining, are prohibited in organic wine production under EU regulation n. 203/2012. To address this issue, the present study explored an organic-friendly solution that involves the use of a pectolytic enzyme with secondary glycosidase activity. The enzyme was validated in Chianti wine production and was observed to significantly accelerate the hydrolysis of glycosylated quercetins, giving their aglycone form. This accelerated process enhanced deposition before bottling without causing significant wine colour depletion, thus can be considered a promising approach even for organic winemakers.

The agroecological transition is an essential issue for vineyards, given the high pressure surrounding the use of pesticides to protect the crop. Major changes are required in winegrowing systems in order to achieve sharp reductions in the use of these inputs. With the aim of providing technical and practical benchmarks on the performance of agroecological systems, we have built and evaluated scenarios using multiple-criteria decision analysis.

A study of changes in oxygen transfer through micro-agglomerated corks was carried out over 24 months under controlled storage conditions (Chanut et al., 2023a). This work demonstrated that the glass/cork interface can represent a major entry route for oxygen into wine bottles. It also showed that there is no difference in oxygen transfer at 20°C between bottles stored horizontally and vertically. However, high storage temperature greatly increases oxygen transfer at the interface between the cork and the bottleneck.
