Chateau Haut-Brion is the "more intellectual and less understood" of Bordeaux's first growths, according to its current owner, often displaced by the arguably more illustrious Lafite, Latour, Margaux and Mouton-Rothschild.

Prince Robert of Luxembourg said Haut-Brion has always been the most popular among professionals in Bordeaux and those in the wine trade, but less so with the general public, the Drinks Business reports.

This is partly because the chateau is so much smaller than the other first growths, he added, with just 48 hectares compared with Latour's 100.

Prince Robert went on to say that Bordeaux's second growths "are becoming more and more visible" and they need to be "if not as great as the first wines, very worthy of the name".

Speaking to Luxist recently, Prince Robert said he plans to expand Domaine Clarence Dillon by producing a more affordable blended wine, named Clarendelle, on a larger scale.
