Château Tanunda unveils lightweight and smaller formats with a refreshed look

Château Tanunda has announced “three key innovations” across its Grand Barossa range in 2026, including a shift to smaller format bottles. The winery said that the introduction of a 275ml format for its Grand Barossa Shiraz positions it “in a strong way to move with ongoing moderation and occasion-based trends”. Alongside the small format bottles, Château Tanunda will also release a proprietary lightweight bottle and a new label design intended to reduce carbon emissions and draw attention in retail. Managing director Michelle Geber said the combined initiatives bring together the winery’s dedication to showcase the Barossa wine region with sustainability.
