Robert Parkers's Wine Advocate
Exceeding my prebottling expectations, the 2016 Cotes du Rhone Les Quartz is a terrific effort that puts many Châteauneufs to shame. Aromas of crushed stone and raspberries mark the nose of this 8515 Grenache-Syrah blend. It's full-bodied and rich, with hints of chocolaty ripeness balanced by citrus zest on the lengthy finish.

The 2016 Côtes du Rhône Quartz offers a rare level of minerality and depth for a Côtes du Rhône, and anyone that loves southern Rhônes should buy bottles of this. Black raspberries, hints of cassis, crushed rock and dried garrigue characteristics flow to a rich, concentrated - even structured - effort that has the telltale elegance and purity of the estate. With ripe tannin, solid freshness and a great, great finish, it's going to drink nicely for a decade.
