Chateau Phelan Segur

Bernard O'Phelan, an Irish wine trader, left his hometown of Tipperary and settled in Bordeaux in the late 18th century. At that time, the town was a vital trading place with Brittain, and O'Phelan quickly established close relations with families in the wine trade. Through these links, he married the daughter of Daniel Guestier, a renowned wine trader in Bordeaux. With his father-in-law's experience, O'Phelan decided to produce his own wines and purchased Clos de Garramey in Saint-Estèphe in 1805 and Ségur de Cabanac estate in 1810.

The Palladian-style Château, which dominates the summit of a hillock facing the estuary, was built in the heart of a park which stretched towards the port of Saint-Estèphe. 

At the start of the 20th century, Château Ségur de Garramey changed its name to Château Phélan Ségur, reflecting the property's classic and noble values, blending innovation and heritage.

Château Phélan Ségur's vineyards spans over 70 hectares of clay-gravel soils on the hillocks and plateaus of Saint-Estèphe. The vineyards comprise four large sections, which are adjacent to other renowned vineyards like Châteaux Montrose and Calon Ségur. The grape varieties are Cabernet Sauvignon (58%), Merlot (39%) and 3% of Cabernet Franc and Petit Verdot. The latter grape was incorporated in the blend since 2015.

The last 25 years the wines of Phelan Segur scored increasingly better per vintage. Excellent high scoring vintages include 2005, 2009, 2010, 2016, 2017, 2018, 2019, 2020, 2021.
