`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

The 2009 vintage was very successful with some excellent wines made. Shiraz was strong but Grenache and Mourvedre were also very good. After the extreme temperature of the second half of the 2008 vintage, it was good to receive average rainfall over winter and follow up rains of 100mm in November and December. This was followed by a period of hot weather in late January, lasting through to early February. Conditions from then on were favourable with no extreme heat and little rain until late April. Vintage started two weeks later than 2007 & 2008 with yields generally down. Shiraz in particular was down with yields the lowest since 2003.


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

Deep crimson, purple-red in colour. Fragrant spice nose, combining aromatic red fruits and savoury notes. The palate is a flavoursome compote of red and black fruits with a variety of spices. Youthful fine tannins balance the rich fruit intensity. Subtle oak adds to the structure and complexity.
