Wine Chateau Cantenac Brown 3eme Grand Cru Classe Red. A ‘third’ Grand Cru Classe from the Margaux region and specifically from the village of Cantenac, with a chateau that architecturally resembles a Scottish style more than the neighboring chateaux. Logical, since the owners who built it in the 19th century had Scottish roots. Approximately 2/3 Cabernet Sauvignon and 1/3 Merlot, along with a little Cabernet Franc, give a flawless wine that one sip convinces you why Cantenac Brown fans are fanatics. Try it both young and after its 20th birthday.
