Keg wine on tap: a sustainability-oriented innovation

Abstract

How could the wine industry be more sustainable? To answer this, an Interreg French-Swiss project gathered researchers to help a French keg producer and a Swiss wine distributor make their innovation more ecological, social and economical. What innovation? A reusable plastic keg with a disposable airtight pouch inside.

To assess the environmental impacts of this keg compared to glass bottles and help its eco-conception, IFV did a Life Cycle Assessment (LCA). Six indicators were considered as relevant. Results show an environmental benefit of the reusable keg except for resources depletion. A shift from aluminium to plastic pouch and from single use to washable pouch’s head could improve the keg ecological profile.

The Changins School of Viticulture and Oenology tested the suitability of the keg for the conservation and consumption of wines, by chemical and sensory analysis. The nature of keg materials was studied in different storage conditions. A HACCP was also carried out to ensure the quality of the wine, from conditioning step to dispensing system. Results confirmed the capacity of the keg to ensure wine quality and protect wines against oxidation, offering a real opportunity for sulphite free wines.

Market studies conducted by Ecole Hôtelière de Lausanne show that winemakers, as well as 64% of restaurateurs and 96% of wine consumers are in favour of kegged wine, mostly for economic savings, and for its sustainability, respectively. Kegged wine also results in optimal logistics from wineries to restaurants, more customer-centric staff, better service efficiency, and improved consumer experience, by meeting a growing demand for wine by the glass. Finally, keg wine served on tap is seen as a sustainable-oriented innovation that benefits all wine industry stakeholders.

Mineral-wine profile and AI: wine authentication and identification

Enhancing the mineral wine profile: from authentication to identification by artificial intelligence for enhanced security. Analysis of a wine’s mineral concentration profile provides a distinctive fingerprint for each cuvée. Unlike organic profiles, this identification signature remains stable over time and can be deciphered using direct analysis by inductively coupled mass spectrometry (icp-ms).

The socioclimatic dynamics and the table grape production during a long-drought: the case of Brazilian semiarid

In 2022, the area cultivated with grapes in Brazil counted 75 thousand ha. About 1/2 of the grape production is located in rio grande do sul state, in South Brazil. Nonetheless, the northeast region, especially the Sao Francisco River Valley (SFRV), is increasing its area and production, mainly pushed by table grapes. The states of bahia and pernambuco already respond for circa 1/3 of brazilian grape production.

Identification of natural terroir units for viticulture: Stellenbosch, South Africa

Une unité de terroir naturel (UTN) peut être définie comme une unité de terre qui est caractérisée par une relative homogénéité topographique, climatique, géologique et pédologique. De telles unités sont de grande valeur pour mieux comprendre le système terroir/vigne/vin. Le but de cette étude est de caractériser la région viticole du Bottelaryberg. – Simonsberg-Helderberg en utilisant une information digitale existante et d’identifier des UTN en utilisant un Système d’information Géographique.

REMEDIATION OF SMOKE TAINTED WINE USING MOLECULARLY IMPRINTED POLYMERS

In recent years, vineyards in Australia, the US, Canada, Chile, South Africa and Europe have been exposed to smoke from wildfires. Wines made from smoke-affected grapes often exhibit unpleasant smoky, ashy characters, attributed to the presence of smoke-derived volatile compounds, including volatile phenols (which occur in free and glycosylated forms). Various strategies for remediation of smoke tainted wine have been evaluated. The most effective strategies involve the removal of smoke taint compounds via the addition of adsorbent materials such as activated carbon, which can either be added directly or used in combination with nanofiltration. However, these treatments often simultaneously remove wine constituents responsible for desirable aroma, flavour and colour attributes.
