Murray Street Vineyards, a winery at Greenock in South Australias Barossa Valley, was founded in 2001 by William (Bill) Jahnke, an American investment banker, and Barossa winemaker Andrew Seppelt. The winery on the estate was finished in 2007, in time for vintage.
In 2014 the business became fully family-owned, when Janai Brengman joined her father as co-owner. In October 2026 they sold the winery, the brand, the cellar door and the vineyards to Sandy Oatley and his daughter Nicky, of A.G. Oatley Wines.
Janai put it this way: We are incredibly proud of the wines and community we have built over the past 25 years, and we are confident the Oatley family will guide the brand into its next exciting chapter. Sandy said the Oatleys were honoured to be its next custodians, and that as a family business themselves they share the values that shaped Murray Street.
Murray Street has gone from one father and daughter to another, and the Oatleys say they want to build on the legacy Bill and Janai created.
Congratulations to Bill Jahnke and Janai Brengman on 25 years of Murray Street, and to Sandy and Nicky Oatley on taking it on.
