Vieux Château Chambeau, specifically their 2018 vintage. The wine is primarily made from Merlot grapes, which contribute to its supple and round character. Merlot is known for producing wines with smooth tannins and a soft texture. The addition of Cabernet Franc adds a silky charm to the wine, enhancing its overall profile.

The balance between these two grape varieties is achieved through the aging process in barrels. This aging imparts additional flavors, aromas, and textures to the wine, leading to a final product that is elegantly balanced and well-rounded.
