Robert Parker's Wine Advocate (RP): 94+
"While it is eclipsed by the brilliance of the 2005, the 2006 Monte Bello (68% Cabernet Sauvignon, 20% Merlot, 10% Petit Verdot, and 2% Cabernet Franc) is a very strong effort. Its dense purple color is followed by copious aromas of creme de cassis, licorice, spice box, and a touch of oak. Well-balanced, dense, pure, layered, and rich, its big, rich style is similar to the 2003."

"Deep, bright ruby. Spicy, high-pitched aromas of red- and blackcurrant, cherry, pipe tobacco, rose and smoky Indian spices. Firm, mineral-driven dark berry flavors are given a firm edge by bitter cherry skin and pit notes, with the tobacco note repeating. Supple tannins add structure and carry through the long, sweet, smoky finish. This is showing gentler tannins than I usually expect from a young Monte Bello and I'd bet on it being drinkable before the 2005 and 2004 versions."
