Wine Advocate-Parker :
The 2018 Calon-Ségur is blended of 65% Cabernet Sauvignon, 17% Merlot, 15% Cabernet Franc and 3% Petit Verdot (14.9% alcohol). It is anticipated to age for 20 months in barriques, 100% new. Deep garnet-purple colored, it needs just a little coaxing before it reveals seductive notes of baked cherries, warm cassis, licorice and smoked meats with nuances of hoisin, camphor, Chinese five spice and dried roses with a waft of cardamom. Full-bodied and completely packed with concentrated black fruit and spice layers, it has a firm frame of grainy tannins and a wicked backbone of freshness giving an energetic lift to the very long finish. There's lots of brightness coming from the Cabernet Franc component in here, but it is nonetheless a decadent expression.
