Chateau Beausejour Heritiers Duffau-Lagarrosse

Château Beauséjour Héritiers Duffau-Lagarrosse is a Bordeaux producer rated as one of the prestigious Premier Grand Cru Classé B estates in Saint-Émilion. It makes red wine mostly from Merlot, typical of the style of Saint-Émilion and Right Bank Bordeaux producers.

The property had been a larger single estate until 1869 when it was divided between the two children of its original owner, Pierre-Paulin Ducarpe. The château and half the vineyards were inherited by his daughter, who married into the Duffau-Lagarrosse family. She took her husband's name, which now appears in the estate's full name, Château Beauséjour Héritiers Duffau-Lagarrosse. It has since been passed down through nine generations and remains owned and operated by the family. The other half of the property went to Ducarpe's son and has become the modern estate Château Beau-Séjour Bécot.

Beauséjour has 7 hectares (17 acres) under vine, planted predominantly with Merlot, some Cabernet Franc and a small amount of Cabernet Sauvignon. Beauséjour's reputation grew in the 1990s, when American critic Robert Parker gave the 1990 vintage a perfect 100 points.

In 2009, Nicolas Thienpont from Château Pavie Macquin was hired to modernize Château Beauséjour, along with famous consultants Michel Rolland and Stéphane Derenoncourt. Changes brought on by the trio, including fermentation of whole grapes and punching down in open fermentation tanks, began with the 2009 vintage. The 2009 and 2010 vintages went on to score 100 points each from Parker.

A second wine called Croix de Beausejour is made in conjunction with the grand vin.
