93-Points by Wilfred Wong & Decanter.
Overture is a blend this year of the 2014, 2015 and 2016 vintages, with a dominance of 2016. This is supple with clear ripe berry fruits, generous and fully ripe, tempered by white pepper spice and smoked cedar notes. It has a gentle but confident tannic frame and mouthwatering lift on the finish. This is focused and ready to drink and impresses with its rippling silk texture.
Blend: 77% Cabernet Sauvignon, 8% Petit Verdot, 8% Merlot, 5% Cabernet Franc, and 2% Malbec, aged for 18 months in New French oak. 
 
Elegance and Complexity
Opus One is the realized dream of two men: Baron Philippe de Rothschild of Chateau Mouton Rothschild in Bordeaux and Napa Valley vintner Robert Mondavi. The estate vineyards rise from the western part of Oakville, including 100 acres within the highly acclaimed To-Kalon Vineyard and 70 acres combined between the Ballestra and River parcels surrounding the winery.
Beginning in 1993 and following in the tradition of great Bordeaux estates, Opus One created a fine second wine called Overture. Every acre of the estate vineyard is meticulously farmed with the attention to detail and singular focus required to produce Opus One. This scrutiny carries through the blending process and certain lots will not be included in the final Opus One blend. Yet, when these lots are afforded additional time in barrel along with the added flexibility of blending across multiple vintages, the final wine achieves a remarkable elegance and complexity.
Overture reflects the winemaker’s artistry by showcasing the talent of blending five traditional Bordeaux grape varieties and capturing terroir characteristics of the same variety grown in different soils. However, Overture’s third blending aspect – that of marrying multiple vintages – yields a softer, rounder expression of our estate that can be enjoyed upon release.
