John Duval is a renowned winemaker who spent 29 years as the chief winemaker for Penfolds Grange before starting his own label in 2003. The John Duval 'Annexus' Mataro 2016 is a premium red wine made from the Mataro grape, also known as Mourvèdre, which is typically grown in the Rhône Valley of France.

The grapes for this wine were sourced from old vines in the Barossa Valley, Australia's most famous wine region, and the 2016 vintage was characterized by a mild spring and a warm, dry summer, which produced grapes with excellent ripeness and concentration.

On the nose, the John Duval 'Annexus' Mataro 2016 reveals aromas of dark fruit, such as blackberry and plum, as well as hints of licorice and earthy spices. On the palate, the wine is full-bodied and well-structured, with flavors of black fruit, leather, and a touch of smoky oak. The tannins are firm and provide a long, elegant finish.

This wine is a tribute to the Mataro grape, which is often overlooked but has the potential to produce exceptional wines when grown in the right conditions. The John Duval 'Annexus' Mataro 2016 is a superb example of this, showcasing the complexity and depth that can be achieved with this grape. It is an excellent choice for pairing with grilled meats, hearty stews, or aged cheeses.
