About John Duval:
John Duval began his self-titled label in 2003. Duval graduated from Adelaide University in 1973 with a degree in agriculture and winemaking before becoming a winemaker for Penfolds for the next 29 years. Duval was appointed Chief Winemaker at Penfolds in 1986 and was lucky enough to oversee one of the most dynamic periods of change in the Australian wine industry. He received Winemaker of the Year at the International Wine and Spirit Competition in London in 1989; Red Winemaker of the Year at the International Wine Challenge in London in 1991 and again in 2000; and saw the 1990 Penfolds Grange named the Wine of the Year by the prestigious US magazine Wine Spectator in 1995.
Duval focuses on fruit that comes from older vines in Barossa, including Rhone varietals, leading to one of his stellar ones, "Plexus."
