Château Tanunda has announced a big shift to smaller format bottles, with the introduction of the 375ml format for its Grand Barossa Shiraz.
The move responds to evolving drinking habits, as moderation continues to gain momentum and consumers place greater
importance on drinking less, but drinking better.
Alongside the small format bottles, Château Tanunda will also roll out a proprietary lightweight bottle and bold new label evolution, designed to both reduce carbon emissions and command attention across retail respectively.
Managing Director Michelle Geber said: “As a family-owned winery, we are continually assessing how we can evolve responsibly. Whether through packaging innovation, brand investment or responding to evolving consumer behaviour, while remaining true to our Barossa heritage and continuing to deliver wines of distinction and enduring quality.”
The winery will also introduce a proprietary lightweight Bordeaux-style bottle for its Grand Barossa range. Designed in partnership with Orora Glass, the shift reduces the weight of a six-pack carton by 720g, delivering a 6.8% reduction in CO2
emissions, while keeping the stylistic “Barossa” deboss and red wax stamp signalling classic winemaking style.
“We’re focused on building Grand Barossa’s presence across all retail networks,” Geber said. “Classic wine styles have endured for a reason, they offer consistency and staying power. But for many consumers, committing to a full bottle can feel like too much … either due to price or the risk of not finishing it.
“Our changes are about improving visibility and access, removing the barriers that sit in the way of saying yes at the shelf.”
The Grand Barossa range will also debut a bold new look —designed to elevate our impact, strengthen recognition, and command attention on shelf.
The 375ml Grand Barossa Shiraz will be rolled out across its 2024 vintage this year. The lightweight bottles will roll out with a brand refresh across retailers throughout the year. Independent retailers looking to stock the 375ml Grand Barossa Shiraz should contact Chateau Tanunda.
