How to read this

Capitals mark the stressed syllable. “ahn” is a nasal vowel: say it through the nose, with no n. The French r comes from the back of the throat. The recording is the reference.

The estate Jean Guyon began with 2 hectares at Bégadan in 1989 and grew to 87, the first stone of a group of 8 Médoc châteaux he had gathered by 2012.

The château

Jean Guyon, born in 1949, the son of an antique dealer and a lover of art, bought Château Rollan de By in 1989, with 2 hectares of vines at Bégadan. Then he kept buying: Château Haut Condissas in 1995, Château Tour Seran in 2000, Château La Clare in 2001, Château La Rose de By in 2011, and in 2012 Château Greysac, Château de By and Château du Monthil, which brought his Domaines Rollan de By to 185 hectares.

Rollan de By itself has grown to 87 hectares of clay gravel in the north of the Médoc, planted 70% Merlot and 10% each of Cabernet Sauvignon, Cabernet Franc and Petit Verdot. It is certified Haute Valeur Environnementale (High Environmental Value, the French state’s environmental certification for farms) and follows the Natura 2000 charter. Château Haut Condissas is the top wine of the house: 15 hectares of chosen plots, begun with 3 in 1995, planted 60% Merlot, 20% Petit Verdot and 10% each of Cabernet Sauvignon and Cabernet Franc.
