More Australian winemakers are acknowledging the traditional custodians of their sites as they strive to build connections with First Nations communities.

Official acknowledgements have grown in the community, sporting and business space since being adopted at government events in the early 2000s, with the practice becoming familiar on winery websites and their products.

While Wine Australia and the state wine industry associations have no official policy on the issue, small and medium winemakers have led the way in promoting their respect to the traditional custodians of the land their vineyards are harvested on, with some extending this connection through cultural and educational experiences at their cellar doors.

Cullen Wines in Margaret River is probably the industry's oldest advocate in this space, after pioneering biodynamic winegrowing in Australia.

Managing director and chief winemaker Vanya Cullen often refers to being a custodian of the land and its "energy", acknowledging her wines come from the heart of the land, rather than the mind of the winemaker.

"It's 50 years of sustainable wine growing preceded by 65,000 years of Wadandi sustainable land care," Cullen said about the original inhabitants of her family's Wilyabrup estate.

"Our job is to be custodian to the land, to acknowledge the Wadandi people as the previous custodians with respect, and to look after the ancient Wilyabrup soils."

The biodynamic trailblazer is encouraged by the gradual but growing shift from winemakers to acknowledge the traditional history of their vineyards and sites.

"I think it's a great thing happening in Australia now, that people are acknowledging there was a very sophisticated, cultural and sustainable agriculture way in existence for a long while," Cullen said.

The momentum comes as the Margaret River Wine Association last month held its inaugural pre-vintage Welcome to Country ceremony, acknowledging the heritage of the Wadandi people and their connection to the land.

The association later confirmed the ceremony will become an annual event that will continue to evolve, as others in the industry remain hesitant for fear of getting history wrong, with little documented on the initial connection between First Nations people and the early days of Australian wine in the 18th and 19th centuries.

Drinks industry veteran Curly Haslam-Coates, who's Whole Bunch Collective organisation tackles the lack of representation and diversity in the Australian and New Zealand wine industries, believes First Nations communities can help winemakers uncover the history of how a site has grown and developed.

"We don't really know what happened because that information ... it's that systematic erasure, right?" she said.

"And it's not easily accessible ... because we don't have healthy links with our Indigenous communities around the land.

"The really interesting thing about the Acknowledgment of Country is the more I learn, the more I realise I have so much more to learn about whose country I'm on."

Acclaimed writer Bruce Pascoe, a Bunurong man and author of Dark Emu, had some simple advice for wine producers keen to acknowledge the traditional custodians of their sites.

"They should get in touch with the group from the district where they grow," he said.

This sentiment was shared by Jack Buckskin, a Kaurna and Narungga man who has spent his life recovering First Nations languages and believes traditional names on wine labels add an important level of specificity.

"But seek consultation with your First Nations and traditional owners to make sure you get it right," he said.
