Can the use of rootstocks enhance terroir?

Abstract

Rootstocks are an essential l management tool for diverse viticultural challenges. However, studies that combine sensory evaluation and compositional analysis of berries and wine, to determine whether the use of a particular rootstock in a terroir can influence wine quality are sparse. The aim of this study was to determine the influence of different rootstocks and own roots control on sensory and compositional differences in grape berries and resultant wines

Descriptive Sensory Analysis and compositional measures including GCMS were conducted on berries and wines of Vitis vinifera L. cv Shiraz vines grown on own roots or grafted to three different rootstocks (110 Richter, 1103 Paulsen, Schwarzmann). The study was conducted in an experimental rootstock vineyard in the Barossa Valley, South Australia, during two growing seasons (2009/10-2010/11).

Sensory and compositional differences were found in berries and wines from the rootstock treatments and the own roots control that were reflected in the wine quality scores.

Innovative approaches for fungicide resistance monitoring in precision management of grapevine downy mildew

Effective control with fungicides is essential to protect grapevine from downy mildew, a devastating disease caused by the oomycete Plasmopara viticola. Managing this disease faces challenges in maintaining fungicide efficacy as the number of modes of action decreases and the risk of fungicide resistance increases. Long-term measures should address strains resistant to multiple modes of action, that can be selected by the repeated use of single-site fungicides. For these reasons, a precision management of the disease, that considers the selection of the best fungicide schedule according to the sensitivity profile of the pathogen population, is needed.

Color stabilization properties of oenological tannins

The use of oenological tannins is authorized for many years by the OIV and advised for color stabilization. For this reason, winemakers look for a better understanding of tannins/anthocyanins interactions to produce deeply colored wines with great color stability during aging.

Multi-omics methods to unravel microbial diversity in fermentation of Riesling wines

Wine aroma is shaped by the wine’s chemical compositions, in which both grape constituents and microbes play crucial roles. Although wine quality is influenced by the microbial communities, less is known about their population interactions.

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.

Application of plant growth regulators on Vitis vinifera L var. Mouchtaro affect berry quality characteristics & associated microbial communities

The phenolic profile of the red grapevine varieties berries is a key quality factor and several techniques have been applied to improve it (Perez-Lamela et al., 2007; Singh SK and Sharma, 2010). The last decade the application of resistance elicitors and phytohormones is an innovative viticultural technique (Paladines-Quezada et al., 2021; Alenazi et al., 2019).In the present study, leaves and berries of a Greek red indigenous variety (Mouhtaro) sprayed with two elicitors, benzothiadiazole and chitosan and a plant hormone abscisic acid, during veraison.
