`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, the man who created Australia’s most famous wine. John passed it on to his successor when he left Penfolds in 2003 to start his own label. He sources fruit from long-time friends in the Barossa, all of whom own vineyards with vines aged from 50 to 100 years old. The wines are made with minimal intervention and showcase the best of the Barossa.

The Shiraz was sourced from old vineyards in the Tanunda, Krondorf and Ebenezer regions, Grenache from the Tanunda and Ebenezer region and Mourvèdre from the Light Pass region.

Vintage Information

The 2013 vintage was characterised by a very dry winter and spring which led into a hot summer. This meant yields were low and the fruit was picked earlier than usual, starting in the second week of February.


Fermentation with submerged cap occurred in both traditional old open and small stainless steel fermenters. The wine was then 100% barrel matured for 14 months, with just 8% new fine grain French oak hogsheads (300 litre barrels), and the remainder in three to six year old barrels. Some Shiraz finished fermentation in new French oak.

Tasting Notes

Deep crimson, the 2013 Plexus has an attractive red and black fruit character with savoury undertones. Generous on the palate, with a soft texture and fine soft tannins.
