Mediterranean wines focus on sustainability

Published:  20 October, 2017

The wine sector is to focus on improving its environmental and sustainability commitments to respond to consumer concerns.

Vinisud 2018, the exhibition dedicated to Mediterranean wine, will focus on the issue of sustainable development and ethical accountability during its event on 18 to 20 February at the Montpellier showground.

The aim is to consider how consumer demands have changed with more focus on local products and transparency.

Vinisud will look into the way that the wine sector is adapting with sustainable, organic, natural winemaking practices and vegan wines.

Three international studies will be unveiled covering ethical consumerism in France; environmentally accountable labelling in New York and London and the progression of Mediterranean wines.

There will also be a survey of the responsible initiatives undertaken by exhibitors and a presentation on sustainable consumer habits.

Meanwhile, Bodegas Torres, the Spanish winemaker, has already revealed it is experimenting with technologies to minimise its carbon footprint.

The Penedès family winery said it wants to go a step further in its environmental commitment to reduce its CO2 emissions by 30% a bottle from 2008 to 2020.

Miguel Torres, president of Bodegas Torres, said: “The wine sector has in its own hands the capacity to lead the adoption of CO2 capture and reuse technologies to considerably reduce emissions.”

Bodegas Torres is supporting the research and development of CCR (Carbon Capture and Reuse) technologies, in cooperation with universities and technology companies, to seek ways of making use of the CO2 produced.

Tests carried out at Bodegas Torres are intended to show the range of possibilities offered by these technologies as a future solution for fighting climate change.

The Bodegas Torres environmental team has carried out tests with eight different technologies offering alternative uses of the CO2 produced during fermentation.

These technologies include using microalgae as biomass; carbon fertilisation; or charcoal (biochar) generation.

To obtain energy, tests have been carried out with power-to-gas (obtaining hydrogen from electrolysis of water with electricity from renewable energies), and methanation (transformation of CO2 and hydrogen into methane using methane-producing microorganisms).

In the case of products, CO2 can be used to produce solvents.
