The group was founded in New South Wales by Samuel McWilliam in 1877 and was always family owned, but Gallo bought into the business in 2001.
Chairman Jeff McWilliam, a fifth generation family member, said: “This is a significant milestone in the company’s history. We are a proud multi-generational family-owned wine producer, and the decision to acquire Gallo’s shares in the business was unanimously supported at the recent shareholder meeting.”
Chief executive Rob Blackwell added: “In the past two years, McWilliam’s has undergone significant capital restructuring in order to make our business stronger. This has enabled us to take advantage of opportunities as they arise across the export and domestic markets - and one of the very positive outcomes of this is the company returning to being 100% owned by the McWilliam’s family for the first time in 13 years.”
