The Sustainable Wine Roundtable has added two new signatories to its Bottle Weight Accord. 

The first new signatory is the Australian company Coles Liquor, which operates a network of over 900 Liquorland stores, selling exclusive wine brands including James Busby, Winton Road, Land of Giants, Canard-Duchêne, Whispers, Rock Paper Scissors and more. 

The second is the Australian brand Wirra Wirra, based in McLaren Vale, which has committed to lowering the average bottle weight of its wine ranges to 420g per 75cl bottle. 

Shae Courtney, national quality & sustainability manager at Coles Liquor, said: “Joining the Bottle Weight Accord reflects Coles Liquor’s broader commitment to packaging sustainability through innovation and collaboration with industry partners.  

“It also recognises the progress we have made on the packaging of our portfolio of fabulous wines – and last financial year we reached a milestone of having 98.7% of Coles Liquor Own Brand primary packaging being recyclable, reusable or compostable.” 

Luke Tyler, sales & marketing director for Wirra Wirra added: “We’re proud to join the Bottle Weight Accord as part of our ongoing commitment to reducing environmental impact. While eager to learn from others, we also look forward to sharing our own insights. We’ve recently introduced a new lightweight 410g proprietary bottle without compromising its iconic design that will start appearing in fellow BWA participants’ stores in time for Christmas this year.” 

Delaney Sheridan, operations manager at the SWR said: “As we reach the Accord’s second anniversary, it’s really encouraging to see more members coming on board. Partnerships between retailers and producers, as with Coles Liquor and Wirra Wirra, show what’s possible when the industry moves collectively around a simple, evidence-based target.”
