`Plexus` Barossa Valley Shiraz/Grenache/Mourvedre

Barossa Valley

John Duval

One of the world's great winemakers, John Duval was given the 'Grange' torch...

by Max Schubert and passed it on to his successor when he left Penfolds to start out on his own with the 2003 vintage, sourcing fruit from some long-time friends in the Barossa. His red wines - a Shiraz and a Shiraz/Grenache/Mourvedre blend - are sourced from old Barossa vines aged between 50 and 100 years old and showcase the best of the Barossa region. In 2010 he introduced a white Plexus wine to his range using traditional white Rhône varietals.

Shiraz was sourced from old vineyards in the Krondorf and Marananga regions. Grenache from old bush vines 50-60 years old from Stockwell and Krondorf regions. Mourvèdre from old bush vines, the oldest over 100 years old, from the Light Pass and Krondorf regions.

Vintage Information

A warmer spring and cooler summer summarised the 2012 vintage conditions. Vine health was very good coming out of spring and combined with a mild summer and only three rain events over three months during vintage, this resulted in some excellent wines being produced. Yields were generally slightly below average.


Fermentation with submerged cap in both traditional old open and small stainless steel fermenters. 100% barrel matured for 15 months, with just 10% new fine grain French oak hogsheads (300 litre barrels): 90% three to six year old barrels. Some Shiraz finished fermentation in new French oak.

Tasting Notes

Crimson purple-red with an array of red and black berry aromatics, wild berries and cassis. Generous on the palate, the Plexus has a soft texture and fine tannins. Flavours of blackberry and dark cherry finish with hints of asian spice and Christmas cake.
