Little by little, the team at Opus is refining the style of Overture, although it remains a riper, fruitier wine than the main bottling. A blend of the 2017 and (majority) 2018 vintages, this has a Californian generosity, but is firm in its tannic structure, with softening raspberry and blueberry fruits. It really needs a little time to open in the glass, when a heather, peony and olive tapenade character comes out. Still quite a step between Overture and Opus but this is appealing and succulent. First vintage 1993 but primarily sold cellar door – sold internationally as of 2016.
