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.
