Carbon footprint in Austrian viticulture – Evaluation of the main polluters and possible solutions in entire the production chain

Abstract

This study examines the carbon footprint of Austrian viticulture, with a focus on grape suppliers and wine producers across different regions. The analysis highlights key contributors to emissions, including vineyard replanting, grape production, wine production, using the certification data “Sustainable Austria” from the years 2022 and 2023. The findings reveal regional differences in emissions, with Burgenland, Lower Austria, Styria, Vienna and Carinthia, particularly in grape production. Notably, emissions from vineyard replanting remained consistent across all operation sizes, while grape production and packaging showed significant variation. Larger wineries benefited from economies of scale, displaying lower emissions per unit compared to smaller wineries. However, emissions related to small units (glass bottles…) and packaging remain critical areas for improvement, contributing a substantial portion of the total carbon footprint. The study underscores the need for continued sustainability efforts, particularly in optimizing packaging practices and supporting smaller wineries in reducing their carbon footprint.

 

Empreinte carbone de la viticulture autrichienne – évaluation des principaux émetteurs et solutions possibles tout au long de la chaîne de production

La certification de durabilité “nachhaltig austria” (www.nachhaltigaustria.at ; www.sustainableaustria.com) est proposée depuis 10 ans dans une version en ligne pour les exploitations viticoles autrichiennes et, entre-temps, plus de 25% de la surface viticole autrichienne est certifiée. Depuis la récolte 2022, “nachhaltig austria” calcule automatiquement l’empreinte carbone de chaque domaine viticole, par hectare de vigne, par litre de vin en fût et par bouteille de 0,75 litre (Poelz, W. et Rosner, F.G. 2023).  Les publications de l’année dernière et de nombreuses présentations au niveau national et international ont déjà abordé des sujets tels que le rechargement des bouteilles en verre, les bouteilles en verre légères, les énergies renouvelables, … Etc. Ont été mis en lumière en ce qui concerne l’empreinte carbone. La présente publication compare les millésimes 2022 et 2023 et analyse les questions relatives aux différences entre les millésimes, les régions, les intrants utilisés tels que les quantités et les sources d’énergie, les bouteilles en verre et les emballages, la production de vin biologique versus standardisée, etc. Et discute des solutions possibles.  Ces données sur l’empreinte carbone autrichienne seront utilisées pour contribuer aux discussions internationales en cours sur les normes internationales harmonisées dans le cadre de l’OIV et d’autres plates-formes et initiatives.

Co2-fußabdruck im österreichischen weinbau – bewertung der hauptverursacher und mögliche lösungen entlang der produktionskette

Die nachhaltigkeitszertifizierung “nachhaltig austria” (www.nachhaltigaustria.at; www.sustainableaustria.com) wird seit 10 jahren in einer online-version für österreichische weinbaubetriebe angeboten und mittlerweile sind über 25% der österreichischen weinbaufläche zertifiziert. Seit der ernte 2022 berechnet “nachhaltig austria” automatisch den co2-fußabdruck für jedes weingut, pro hektar rebfläche, pro liter fasswein und pro 0,75-liter-flasche (Poelz, W. und Rosner, F.G. 2023).  In den veröffentlichungen des letzten jahres und in zahlreichen präsentationen auf nationaler und internationaler ebene wurden bereits themen wie die wiederbefüllung von glasflaschen, leichte glasflaschen, erneuerbare energien, … Usw. Im hinblick auf den co2-fußabdruck beleuchtet. Die vorliegende publikation vergleicht die jahrgänge 2022 und 2023 und analysiert fragen zu unterschieden zwischen jahrgängen, regionen, eingesetzten betriebsmitteln wie energiemengen und -quellen, glasflaschen und verpackungen, biologischer versus standardisierter weinproduktion etc. Und diskutiert lösungsmöglichkeiten.  Diese österreichischen co2-fußabdruckdaten werden als beitrag zur laufenden internationalen diskussion über harmonisierte internationale standards im rahmen der oiv und anderer plattformen und initiativen verwendet.

French wine sector facing climate change (part. 2) : the implementation of the national strategy

This summary follows this made by Hervé Hannin et al. Entitled “French wine sector facing climate change (part. 1) : a national strategy built on a foresight and participatory approach “. The french wine sector has taken a collective approach to the issue of climate change, and has officially submitted its strategy to the minister of agriculture in 2021. This industry policy is the result of multidisciplinary work carried out through the “laccave” project (metaprogramme accaf, inrae) and its prospective study designed to anticipate climate change in the french wine industry (aigrain p. Et al., 2016). French wine professionals decided to structure a strategy to deal with climate change du in particular to the presentation made at the 2016 OIV congress in Brazil.

Ceramic imprint in wine: influence of hydraulic ratio on ceramic dissolution and wine pH in amphorae systems

This interaction is primarily due to an acidic attack on the ceramic by the wine. It results in (1) the dissolution of the ceramic into the wine and the release of a wide variety of elements; and (2) an increase of the wine pH. The extent of these effects depends on the mineralogical and chemical composition of the ceramic, as well as the hydraulic ratio of the ceramic-wine system (the term hydraulic ratio (ρ) defines here the volume of wine over the surface area of the ceramic in contact with the wine).

Anticipating consumer preference for low-alcohol wine: a machine learning analysis based on consumption habits and socio-demographics

The global wine consumption landscape is undergoing a transformation, marked by a growing trend towards reduced consumption and a preference for healthier lifestyles. In line with this shift, european union regulation (regulation eu 2021/2117) has recently redefined dealcoholized or partially dealcoholized wine within the wine category.

Reduce sulfur dioxide addition using a natural polymer chitosan phytate

Most oxidation reactions in wine require iron as a catalyst. The iron content of wine has decreased greatly in recent decades due to the use of low or no release cellar materials; however, in some cases it is still necessary to adopt winemaking practices to remove excess iron from wine, prevent its oxidation, and be able to reduce the addition of sulfur dioxide and other antioxidants.

Evolution of oak barrels C-glucosidic ellagitannins

During oak wood contact, wine undergoes important modifications that modulate its organoleptic quality and complexity, including its aroma, structure, astringency, bitterness and color. Vescalagin and castalagin are the two main C-glucosidic ellagitannins found in oak wood used for wine aging wood but lyxose/xylose derivatives (grandinin and roburin e) and dimeric forms (roburins a,b, c and d) are also present. The presence of several hydroxyl groups in the ortho-positions at the periphery of the structure of the ellagitannin isomers allows these molecules to undergo oxidation or condensation reactions with other compounds.
