Zeowine: the synergy of zeolite and compost. Effects on vine physiology and grape quality

Abstract

The trial aims to improve the protection and management of the soil, the well-being of the plant and the quality of production in the wine supply chain organic and biodynamic, using an innovative product “ZEOWINE” resulting from the composting of waste of the wine and zeolite supply chain. At present, the use of zeolites in agriculture is a fast-spreading practice; their application to soils (both as natural zeolites and in combination with organic and mineral fertilizers) not only increases production but also leads to the exaltation of quality indices. The research was conducted in the 2019 season in San Miniato (Tuscany) on the vineyard of Sangiovese in production, performing the following inter-row treatments at the beginning of January: organic company fertilizer, zeolite (clinopthylolite) and zeowine (combination zeolite and corporate compost obtained through grape processing scraps) in the respective doses of 20 t/ha, 10 t/ha and 30 t/ha. Following the treatment, were measured gas exchanges and water potential, berry weight, °Brix, pH, acidity, total and extractable anthoclyanins and polyphenols. Treatments with Zeowine and zeolites reduced water stress. In Zeowine treatment, sugars are lower, while acidity, pH and berry weight do not vary from control. Statistical differences are also noted in the concentrations of anthoclyanins and polyphenols. Results suggest a positive impact of Zeowine treatment on physiology and quality characteristics in V.vinifera.

The challenge of quality in sulphur dioxide free wines: natural polyphenol alternatives

Sulphur dioxide (SO2) seems indispensable in winemaking because of its properties. However, a current increasing concern about its allergies effects in food product has addressed the international research efforts on its replacement. This supposes a sufficient knowledge of its properties and conditions of use. Several studies compared SO2 properties against new alternatives that are supposed to overcome SO2 disadvantages. Firstly, the state of art on SO2 wine replacements is revised, and secondly, the last promising results using natural enriched polyphenol extracts are shown.

Contribution of soil and atmospheric conditions to leaf water potential in grapevines

Etant lié au sol et aux conditions atmosphériques, le statut hydrique influence la physiologie de la vigne d’une part, mais joue aussi un role important en ce qui concerne la qualité du raisin et donc du vin d’autre part. Nous avons mesuré, dans la région de Stellenbosch, le statut hydrique sur des pieds de Sauvignon Blanc non irrigués, implantés sur 2 terroirs différents, l’un froid, l’autre plus chaud.

Influence of soil management and vine water regime on leaf gas exchange, berry composition and quality of Chasselas wines in Switzerland

A soil management and vine irrigation trial was carried out for 4 consecutive years from 2020 to 2023 at agroscope’s experimental vineyard in leytron (Valais, Switzerland) with the Chasselas grape variety (clone 14-33/4, grafted on 5bb). Two types of soil maintenance (bare soil with chemical weeding and sown grass) coupled with two water regimes (with and without drip irrigation from flowering to veraison) were compared in a randomized design with four replicates of 10 vines each.

La place du terroir dans le processus de patrimonialisation : l’exemple des paysages culturels viticoles du patrimoine mondial de l’Unesco

Eleven wine-growing sites are now on the UNESCO World Heritage List as Cultural Landscapes. If the viticultural character of these sites constitutes the main argument for the demonstration of their heritage value, the terroir and its biophysical and environmental characteristics tend however to appear in a minor mode compared to the aesthetic and cultural dimensions. In other words, the “specific characteristics of the soil, topography, climate, landscape and biodiversity” (OIV definition) are most often used as descriptive elements in the presentation of the sites, but it is more the aesthetic, historical,
