Domaine Pierre Usseglio was founded in Chateauneuf-du-Pape by Pierre’s father, Francis in 1948. Pierre eventually took the reigns and, since 1999, his children have run the estate. The Domaine holds 15 small vineyard plots throughout the AOC, totaling 22 hectares. Only one of those hectares is planted to white grapes. The remainder, with a mix of rocky and sandy soils, represent approximately 75% Grenache, 10% Syrah, 6% Mourvedre, 5% Cinsault, 2% Counoise and 2% Muscardin. Domaine Pierre Usseglio makes three red wines and one white.

Cuvee de Mon Aieul is a selection of grapes from vines 75 to 90 years old. They come from plots on La Crau, les Bédines or les Serres, where the soils are sand and stone, covered in the regions famous galets. A pure and concentrated wine, the nose is very complex with notes of raspberries, licorice and spices. It is a powerful wine yet retains great elegance, and is at its best between 10 and 12 years of age.
