Australia is one of the warmest and driest wine countries, with an industry which began in C19 only made viable in many regions using irrigation.

Today with frequent extreme weather events from frost, flooding, bushfires, droughts and warming temperatures, climate change issues in this hot dry land have become a hot topic.  Winegrowers need to find solutions to reducing water useage and their carbon footprint – fast.

Yet I have always been surprised that although Australia is one of the most affected by climate change, it lags far behind in its response.  I tuned into a seminar hosted by sustainability expert Jane Masters MW and the Government of South Australian to find out more.

The good news is that in July 2019 Australia began a national programme called ‘Sustainable Winegrowing Australia’ to help vine growers and winemakers improve sustainability.  This is largely run from South Australia, which makes up 60% of the total membership – mainly from Barossa, Adelaide Hills and McLaren Vale regions rather than the bulkwine engine rooms of hot inland Riverland and Riverina.

“It is a great tool for the industry to make a start”, explained Masters.  “The certification system measures, monitors and reports on growers’ carbon footprint and sustainability practices in six areas: land and soil, waste, energy, water, biodiversity, people and business.  This gives consumers confidence that wines are being made as sustainably as possible”.

To highlight how efforts were being made to improve sustainability, Masters introduced growers from five regions.

First up was Melissa Brown (above), co-owner of Gemtree Wines in McLaren Vale.  Brown had a life-changing experience at a wellness centre, returning home keen to reduce the toxic load in her lifestyle and wines she made.  “This was in the mid-2000s when no-one was talking about climate change”, explained Brown.  “I had to convince my dad this was the way to go”.

Brown pioneered organic and biodynamic practices in her vineyard.  She feels the key part is developing a healthy ecosystem and focusing on biodiversity, planting thousands of native trees and shrubs.  Like other growers she pivoted to growing grapes able to tolerate heat and drought resistance like Fiano, she feels McLaren Vale’s climate is similar to Italy’s Campania, as it has less water requirements than Chardonnay.

Malcolm Leask (above left) set up Hither & Yon becoming South Australia’s first carbon neutral certified winery with an aim to ‘make better wines with a lighter footprint’.  “Monocultures are disfunctional”, says Leask.  “We encourage non-productive zones restoring ecology and native grasses with mixed agriculture allowing cattle to graze freely in our vineyards”.  Leask also plants drought-resistant Aglianico, Touriga Nacional and Nero d’Avola.

In the hot dry Riverland, where Scots-born Giles Cooke (above) of Thistledown Wines buys grapes, the situation is serious with low water levels.  “Irrigation has largely moved away from open channel or overhead sprinklers to a drip system from pressurised pipes allowing growers to adjust to the bare minimum water useage”, says Cooke.

However, as Cooke explains, many Riverland growers are still not taking climate change seriously.  “They are somewhat removed from global climate challenges, more focused on personal survival”, he says.  “In my opinion leadership on this issue needs to come from the big players and this has not happened, so smaller growers are leading the way…but this is a slow process”.

Nigel Blieschke at Torbreck Vintners in Barossa Valley has a different problem.  He dry farms (no irrigation) a treasure trove of over 25 hectares of precious old Grenache and Shiraz vines, some over 125 years old.  To protect and keep these gnarled old vines thriving in the hot drought conditions he has altered canopies to bush vines to protect from hot sun, uses composting to retain moisture, mulching and undervine weeding with sheep for grazing.

The first independent winery in Australia to sign up to the Paris Agreement’s science-based targets was Wakefield Wines in South Australia’s Clare Valley, who have moved to solar and green power.  Wakefield’s director Clinton Taylor aims to cut the winery’s emissions by 50% by 2030.

“We are trialling the new PET flat plastic bottle which gives enormous savings compared to glass, weighing 63 grams compared to glass bottle’s 360-500 grams – and 87% of this PET bottle is recyclable”, says Taylor.

Shipping heavy glass bottles across the globe from down-under is not sustainable in the future.  Some winemakers are making subtle changes switching to lighter glass.

“At Thistledown Wines we changed the bottle weight on Gorgeous Grenache Red 2021 saving 17 tonnes of glass”, says Cooke.  “Most barely noticed, but it demonstrated to us how easy it was to make a change”.

Today this new light-weight bottle is Thistledown Wines’ largest selling wine across the world – so clearly their customers welcomed this move to a more sustainable wine drinking future.
