If you read only one of my Bordeaux articles this year, make it this one. In twenty years of visiting the region I have never come across a property like this Margaux, never seen vines as ancient as these and never met a winemaker like Jean-Pierre Boyer, one of the last of his kind. Bel-Air Marquis d’Aligre illustrates what Bordeaux has gained with modernity and money, and what it has lost.
