Enhancing grape traceability from grower to consumer through GS1 Standards: A case study of the Australian table grape industry

Traditionally, non-saccharomyces yeasts were deemed undesirable in winemaking, for this reason, it is a common practice to add sulphites to prevent their proliferation during the initial stages of vinification. However, the current research on yeast diversity has unveiled numerous non-saccharomyces strains possessing advantageous traits that enrich the sensory profile of wines. The genus hanseniaspora is often associated with wine fermentation and is also commonly found on grapes.

Viti-tunnel®, une innovation imaginée pour répondre à deux des objectifs majeurs des viticulteurs : 1.la sécurisation de la vendange : viti-tunnel® permet de protéger les vignobles des pertes de récolte dues aux maladies, au gel et à la grêle. 2.la réduction des pesticides : viti-tunnel® permet de réduire de plus de 90 %, le recours aux produits phytosanitaires et aux passages de pulvérisateurs, et ce, en toute sécurité pour la vendange. Un dispositif automatisé pour protéger les vignes viti-tunnel® est un dispositif de mise à l’abri automatique des rangs de vigne pendant les pluies et les évènements climatiques extrêmes.

This paper aims to (i) identify the state of the art regarding digital transformation in the transition to sustainability in the wine industry, (ii) analyze the adoption of digital technologies at different stages of the winemaking process and their contribution to the triple bottom line of sustainability, and (iii) present a research agenda that facilitates the development of the field, providing contributions to both literature and managerial practice.

The presence of undesirable compounds in wines, such as ota, biogenic amines and pesticides residues, affects wine quality and can cause health problems for the consumer. Additionally, an excess of tannins can produce an undesirable increase in the astringency and bitterness of the wine, so tannins are also a target for reduction. The main tool that a winemaker has to reduce their content in the wine is fining. However, some of the fining agents commonly used in the winery can cause allergies or even increase the protein content in the wine, increasing the turbidity.

The article presents the results of a study on the technological features of producing sparkling wines of the Pétillant Naturel (Pet-Nat) type, made using the ancestral method from the Muscat Ottonel and Pinot Noir grape varieties.
