A.C. Byrne & Co Margaret River Chardonnay

A.C. Byrne & Co is a wine brand primarily associated with the Margaret River region in Western Australia, known for producing premium cool-climate varietals like Chardonnay. The brand name pays homage to the legacy of the Byrne family, who have a long-standing history in the Australian wine industry dating back several decades.

While the brand maintains a boutique image, it is a private label brand developed and owned by the multinational retail giant ALDI. By leveraging direct relationships with growers in premium regions like Margaret River, ALDI is able to offer award-winning wines at competitive price points. The manufacturing process takes place locally in Western Australia to ensure the geographical integrity of the Margaret River designation.

As of 2026, the brand remains under the ultimate ownership of ALDI South (Aldi Süd), headquartered in Germany. The brand serves as a core part of ALDI's premium alcohol selection in Australia and various international markets, highlighting regional Australian winemaking expertise through a corporate-backed supply chain.
