• SWR Member Interview: Lessons on lightweighting from Wirra Wirra

  In this Sustainable Wine Roundtable Member Interview podcast, I’m joined by Luke Tyler, marketing and sales director, and Matthew Deller MW, CEO of Wirra Wirra. Located in South Australia's McLaren Vale, the winery exemplifies what the region is well-known for: premium red wine and a strong commitment to sustainability. Wirra Wirra has a long history of sustainable practices, with current initiatives spanning across waste reduction, decarbonisation, biodiversity, packaging, and a reconciliation action plan. In recent years, lightweighting has been a major focus, and this year the winery introduced a proprietary 410g glass bottle across a significant portion of its production. Matt and Luke share practical insights into the lightweighting process, the importance of partnerships across the value chain, and why they chose to join the Sustainable Wine Roundtable and the Bottle Weight Accord.

• From the Roundtable: Myths, facts, and what’s next in sparkling bottle lightweighting

  In this episode of From the Roundtable, I’m joined by SWR’s Delaney Sheridan and Dr Peter Stanbury to share some updates – and clear up a few misunderstandings – about lightweighting sparkling wine bottles. SWR is developing a new Sparkling Bottle Weight Accord, building on the success of the still wine Bottle Weight Accord (BWA) launched in 2023. We discuss the progress of the BWA so far, what makes sparkling wine more complex, and how we’re working through those challenges. There are many opinions when it comes to bottle weight, and it can be hard to separate fact from fiction. We thought we’d help set the record straight and run through some of the most common claims. Fact or fiction? Have a listen to find out.
