John Duval is one of Australia's most highly regarded winemakers. As Penfold's Chief Winemaker and custodian of Australia's famous Grange, he was instrumental in establishing Penfolds as one of the world's great wineries.

The inspiration of the Barossa Valley’s old vine, low yielding Shiraz, Grenache and Mourvedre created Plexus, combining elements into a beautifully structured blend. Traditional winemaking practices and fifteen months in French oak barriques will ensure the age worthiness of this first ever release, ensuring a long cellar life.

Entity Shiraz is an intricately structured wine comprised of rich and vibrant Shiraz fruit. A true reflection of Barossa’s soil and climate, Entity displays deep color and distinctive structure. Intense and elegant, Entity expresses aromas of ripe blackberry, blueberry, and a hint of spice.
