John Duval was a winemaker with the renowned Australian winery Penfolds Grange for 29 years.
His love of wine began with his family, who owned quality vineyards to the south of Adelaide, Australia, providing Shiraz grapes and vine cuttings to Penfolds.
He began to work for Penfolds in 1974 and was named Chief Winemaker there in 1986.
During his time with the Australian winery, John supervised a dynamic period of development, winning many awards and a great deal of recognition for his wines and helping to establish Penfolds as one of the world’s great wine brands.
In 2003, he began to work with Ventisquero Wine Estates, co-creating the winery’s flagship wines Pangea, Vértice and Enclave with Felipe Tosso. That same year, he launched his first wine, Plexus, for John Duval Wines.
He currently lives in the Barossa Valley, which is one of the most famous wine regions in Australia, and travels to Chile annually to work on blends at Ventisquero.
