`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 Krondorf, Marananga and Ebenezer districts, the Grenache from Tanunda and Krondorf regions and the Mourvèdre from the Light Pass and Krondorf regions.

Vintage Information

The 2014 vintage had some challenges. After a good winter and early spring rains, the soil profiles were generally full, but a combination of a windy spring with northern Barossa frosts did dramatically reduce the production for some vineyards. A dry late spring and hot start to summer was brought to a holt in mid-February, by significant rain and then cooler conditions for the remainder of the vintage. Due to the rain, harvesting of the red grapes was delayed until the end of February.


Fermentation was carried out with the cap submerged and in small open stainless steel fermenters. The wine was 100% barrel maturated for 14 months, with just 10% in new fine grain French oak hogsheads (300 litre barrels), the barrels were between three and six years old.

Tasting Notes

Vibrant purple-red colour. The nose has attractive ripe red and black fruits aromas, which are complemented by savoury, spicy notes. On the palate, the wine has a good intensity of bright, plush blackberry fruit and Christmas cake character. An appealing texture with a soft tannin backbone.
