Chateau Siran

Chateau Siran is an unclassified Margaux estate in the commune of Labarde, one of the appellation's most consistent over-performers relative to its formal status. The estate covers approximately 25 hectares planted to 55% Cabernet Sauvignon, 25% Merlot, 15% Petit Verdot, and 5% Cabernet Franc — a notably high Petit Verdot component that distinguishes the wine's aromatic and structural profile. The estate is owned by the Miailhe family and has been managed with consistent quality focus since the 1960s. Petit Verdot at 15% contributes violet, pepper, and firm structural tannin that gives Siran more aromatic complexity and aging potential than a similarly priced Margaux might suggest. The second wine is S de Siran. The estate has long sought classification, and its quality record has regularly attracted commentary from critics arguing it deserves inclusion in a revised Médoc classification. At auction, Siran averages $67 per bottle across 224 lots with peaks to $584 — a price range indicating that vertical lots of older vintages (1989, 2000, 2010) command significant premiums. The estate offers Margaux appellation prestige without classification premium, positioning it as one of the left bank's most compelling value addresses. The 15% Petit Verdot content also extends the wine's cellar life meaningfully, as this late-ripening variety contributes tannins that maintain structural integrity well beyond the typical Médoc aging window.
