Lovely, soft tannins with a juicy and flavorful palate of currants, slightly toasted oak and chocolate. It’s full-bodied and layered with a plush texture and a long, flavorful finish. Warm and rather flamboyant for the vintage. Try in 2025.

Tight and concentrated fruits, this is knitted down right now, more muscled than many in the appellation and will need a good few years to soften. Clear dark spice, the Petit Verdot is pulling its weight and making its presence felt not just in the fruit quality but the sappy nature of the tannins, springly tightly shut on the finish.
 
93 Points Jeb Dunnuck
One of the finest vintages I've tasted from this château, the 2019 Château Siran has a great bouquet of ripe black cherries, blackberries, scorched earth, leather, and cedary herbs. With medium to full-bodied richness, polished tannins, and outstanding overall balance, it's going to benefit from 2-4 years of bottle age and drink nicely over the following 10-15 years. It's an impressive Margaux. Best After 2024.

92 Points Wine Spectator
Seductive, showing warmed plum and blackberry compote notes that are lush in feel, with pretty violet and anise hints and a flicker of black tea through the finish. This is hard to lay off of now because of its generosity. Cabernet Sauvignon, Merlot, Petit Verdot and Cabernet Franc. Drink now.
 
91 Points Robert Parker's Wine Advocate
Exhibiting aromas of rich currant fruit and creamy new oak, the 2019 Siran is medium to full-bodied, rich and fleshy, with lively acids and ripe, powdery tannins that assert themselves on the youthfully chewy finish. This is a flavorful, nicely balanced wine that will reward a bit of bottle age. Best After 2025. Rating: 91+
