The chances for using non-saccharomyces wine yeasts for a sustainable winemaking

Abstract

Climate changes and the trend towards organic and more sustainable winemaking highlighted the need to use biological methodologies. The reduction in the use of SO2, the need for the reduction of ethanol content of wines, and the need to reduce or avoid the use of chemical phytosanitary products have prompted the search for alternative practices. In this context, the use of non-Saccharomyces wine yeasts is promising for achieving environmental, economic, and health sustainability objectives.

Here, it is presented the various possible uses of non-Saccharomyces wine yeasts in the entire winemaking chain, from the vineyard for phytosanitary protection and control of the grape microbiota to biocontrol actions in the pre-fermentation and fermentation phase for the reduction of the use of SO2, to use in mixed fermentations to reduce the alcohol content of wines, to use in the drying of the grapes for the production of special wines and post-harvest. These uses, as amply demonstrated by the literature, are also associated with an improvement and an increase of complexity of the sensorial analytical profile of the wines.

Les possibilités d’utilisation de levures œnologiques non-saccharomyces pour une vinification durable

Les changements climatiques et la tendance vers une viticulture biologique et plus durable ont mis en évidence la nécessité d’utiliser des méthodes biologiques. La réduction de l’utilisation du so2, la teneur en alcool des vins et la nécessité de réduire ou de supprimer les produits chimiques phytopharmaceutiques incitent à rechercher des pratiques alternatives. Dans ce contexte, l’utilisation de levures non-saccharomyces vinari est prometteuse pour atteindre les objectifs de durabilité environnementale, économique et en bonne santé. Cette présentation illustrera les différentes utilisations possibles des levures non-saccharomyces vinari tout au long de la chaîne vinicole, depuis le vignoble pour la protection phytosanitaire et le contrôle du microbiote du raisin, jusqu’aux actions de biocontrôle dans les phases de pré-fermentation et de fermentation pour la réduction de l’utilisation du so2 , utilisation en fermentations mixtes pour réduire la teneur en alcool des vins, utilisation dans le séchage des raisins pour la production de vins spéciaux et en post-récolte. Ces utilisations de levures non-saccharomyces, comme le démontre abondamment la littérature, sont également corrélées à une amélioration de la complexité et du profil analytique sensoriel des vins.

Le opportunità di impiego dei lieviti vinari non-saccharomyces per una vitivinicultura sostenibile

I cambiamenti climatici la tendenza verso una vitivinicultura biologica e più sostenibile hanno messo in evidenza la necessità di impiego di metodi biologici. La riduzione dell’uso della so2,   del contenuto alcolico dei vini e la necessità di riduzione o eliminazione di  fitosanitari chimici hanno sollecitato  la ricerca di pratiche alternative. In questo contesto, l’impiego die lieviti non-saccharomyces vinari sono risultati promettenti per raggiungere gli obiettivi di sostenibilità ambientale, economica e salutistica. Qui verranno illustrati i vari possibili impieghi dei lieviti non-saccharomyces vinari in tutta la filiera di vinificazione dalla vigna per la protezione fitosanitaria ed il controllo del microbiota dell’uva, alle azioni di biocontrollo in fase prefermentativa  e fermentativa per la riduzione dell’uso della so2, all’impiego in fermentazioni miste per la riduzione del contenuto alcolico dei vini, all’uso nell’appassimento delle uve  per la produzione di vini speciali, e nella post-raccolta. Questi impieghi dei lieviti non-saccharomyces, come ampiamente dimostrato dalla letteratura, sono anche correlati ad una miglioramento della complessità e del profilo analitico sensoriale dei vini.

Raman spectroscopy as a rapid method to assess grape polyphenolic maturation and wine malolactic fermentation on site

Wineries can increase their economic and environmental sustainability by optimizing the winemaking procedures, from harvest to wine maturation and conservation. Based on analytical data of the chemical composition and wine sensory evaluation, the enologist makes his own decision regarding the enological interventions at the harvest date selection, winemaking and post-winemaking.

Unveiling the bioactive potential of aglianco grape pomace: oleanolic acid as a promising natural product

The winemaking industry generates a substantial amount of byproducts, including grape pomace, which is often discarded as waste. However, this seemingly useless material holds a wealth of bioactive compounds with potential health benefits. Recognizing the value of circular economy principles, this study delves into the comprehensive chemical analysis of aglianco grape pomace, aiming to transform this byproduct into a valuable resource.

Does treatment of grape juice with aspergillopepsin-i influence wine aroma?

Acid aspergillopepsins-i (ap-i) have been suggested for use in winemaking due to their ability to degrade proteins, which reduces haze formation and the necessity for bentonite to achieve protein stability. These endopeptidases cleave non-terminal amino acid bonds of proteins, resulting in their degradation.

Understanding the physiological responses of Sauvignon blanc vines to sequential extreme weather events: implications for vineyard management in a changing climate

Climate plays a predominant role in vines’ growth and productivity and several environmental variables are already known to pose challenges to grapevine production and the horticultural industry as a whole. In this context, a number of extreme weather events already occurring and expected to occur in the next decades even more frequently and with higher magnitude results from current climate change scenario. The aim of this study was to examine the physiological responses of roots, leaves, and berries of Vitis vinifera cv. Sauvignon blanc to consecutive and combined stressors simulated in a semi-controlled environment.
