Château Tanunda is set to unveil three key innovations across its Grand Barossa range in 2026, including a big shift to smaller format bottles.
The introduction of the 375ml format for its Grand Barossa Shiraz positions themselves in a strong way to move with ongoing moderation and occasion based trends.
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 says the combined initiatives bring together the winery’s dedication to showcase the premium Barossa wine region with sustainability.
“As a family-owned winery, we are continually assessing how we can evolve responsibly,” she says.
“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.”
Château Tanunda’s inaugural 375ml release of its Grand Barossa Shiraz responds to evolving drinking habits, as moderation continues to gain momentum and consumers place greater importance on drinking less, but drinking better.
In addition to the new half-size format, the winery will 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 percent reduction in CO2 emissions, while keeping the stylistic ‘Barossa’ deboss and red wax stamp signalling classic winemaking style.
It’s a move that reflects a broader shift gaining traction over the past five years, with industry bodies such as the Margaret River Wine Association identifying lightweight glass as a key lever in reducing wine’s overall carbon footprint.
Geber said, “We’re focused on building Grand Barossa’s presence across all retail networks.
“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, timeless and unmistakable new look.
“Designed to elevate our impact, strengthen recognition and command attention on shelf like never before, signalling the pinnacle of Barossan winemaking at a glance,” Geber said.
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.
