The vineyard of Château de Rouanne is a unique single block, planted entirely with 50+ year old vines, which are a selection massale of Grenache, Syrah and Mourvèdre. The ancient terroir is comprised of limestone and sandy marl soils dating back to the Pliocene epoch.
Louis Barruol, owner and winemaker of Château de Saint Cosme, uses whole bunches during fermentation, as the stems absorb alcohol and help retain acidity and tannin. Indigenous yeasts are used to impart the character and the purity of the terroir into the wine. The wine is aged for 16 months in concrete vats and is bottled unfined and unfiltered in order to deliver a “straight to the ground” interpretation of this unique vineyard.

'Upon first whiff, this wine evokes the spirit of Barruol, with a spicy red berry and rhubarb compote bouquet lifted by cedar and warm spice. Though still tightly wound, it hints at layered complexity beneath the surface. With aeration, the palate expands, weaving garrigue into pure plumy fruit, topped with a savory layer of Nyons olives. A wine of quiet power and elegance—best revisited after 2030 to witness its charming expression."

"Dark and meaty with a wealth of wild-blackberry aromas, this is bold and powerful on the full-bodied palate. Generous fine-grained tannins. Incredible mountain freshness on the front- and mid-palates then intense licorice flavour in the long, very focused finish."
