John Duval is one of Australia's most acclaimed winemakers, with deep roots in South Australia’s Barossa Valley. His passion was cemented during a 28-year tenure at Penfolds, where he rose to Chief Winemaker and played a pivotal role in the legacy of the iconic Grange. Recognized globally, his accolades include International Winemaker of the Year and Wine Spectator’s Wine of the Year. In 2003, Duval launched his own label—John Duval Wines—focused on the Barossa’s low-yielding, old-vine Shiraz, Grenache, and Mourvèdre. His wines are known for their intensity, complexity, and regional character. In 2016, his son Tim joined the family business, ushering in a new generation. Duval draws from decades of experience and a deep understanding of the Barossa to craft wines of place. He employs submerged-cap fermentation in open-top tanks for gentle extraction and favors minimal new oak to highlight old vine fruit purity. His wines—layered, structured, and restrained—stand out for their elegance and aging potential. With its warm climate and treasured old vines, the Barossa Valley yields fruit of great concentration and character. Thanks to long-standing grower relationships and deep regional knowledge, Duval has access to some of Barossa’s finest sites. The John Duval wines are a tribute to the land’s heritage and potential.
