Château Cos d’Estournel has been making wine of first growth quality for years, but the period of ownership under Michel Reybier has coincided with a dramatic shift in ambition and overall quality. And not just in the main wine. Pagodes de Cos, the second label, in recent years is now better than many vintages of the grand vin itself in the 1990s. Yet, while there has been a string of impressive wines here in the last few vintages – 2014, 2015 and 2016 are all exciting editions of Cos – 2018 is a real marvel. I reckon it is possibly the finest wine made in the last decade at the estate. And, in what is a truly remarkable vintage for St Estèphe, Cos might actually just pip the extraordinary wines also made in this year at Château Calon-Ségur and Château Montrose. 

As chief winemaker at Penfolds for a decade, responsible for Grange and the rest, Peter Gago holds unarguably one of the wine industry’s plum jobs. He’s also a master entertainer. I don’t think I’ve attended a wine tasting tutored by a more dynamic personality. Gago was constantly on the move, gliding up and down the floor of the ‘masterclass’ theatre at the London Wine Fair in May as if on stage at Wembley arena.
