In 2003, John Duval established his eponymous label, with a focus on old vine Barossa Valley Shiraz, along with some select other Rhone varietals.
Traditional, low intervention winemaking techniques are employed with Plexus, allowing the wine to be approachable in its youth, but also have medium term cellaring potential for 8-10 years.
Variety: Shiraz 52%, Grenache 30%, Mourvedre 18%. The Shiraz was sourced from old vineyards in the Krondorf, Ebenezer and Eden Valley regions, Grenache from the Tanunda, Ebenezer and Greenock regions and Mourvèdre from the Light Pass and Ebenezer regions.
Winemaking: Fermentation with submerged cap and small open stainless steel fermenters.Grenache saw a small inclusion of whole bunches.
Oak Maturation: 100% barrel maturated for 15 months, with just 13% new fine grain French oak hogsheads (300 litre barrels); with the balance in older seasoned hogseads.
