Wine Advocate-Parker :
The 2015 La Sirene de Giscours is a blend of 65% Cabernet Sauvignon, 30% Merlot and 5% Cabernet Franc. It has a crisp, quite pure black cherry, raspberry coulis and cedar-scented bouquet that gently unfolds in the glass. The palate is medium-bodied with good depth for a deuxième vin, the 30% new oak nicely integrated with good depth and grip on the graphite and spice-tinged finish. This is worth seeking out - the best La Sirène de Giscours to date, but those with a wise head will give it 2-3 years in bottle.
