The winery is located in the municipality Châteauneuf-du-Pape in the area of the same name in the southern Rhone Valley. The ancestors of the current owners had been cultivating a small piece of land with vines, olive and cherry trees since 1670. At that time the business was operated under the family name Féraud. The estate with its current name was founded in 1987. It is managed by Paul Féraud and his daughter Laurence. The name "Pégau" refers to a clay beak wine jug from the 14th century that was discovered during excavations around the Palais des Papes (former papal palace) in Avignon.
The vineyards cover a total of 23 hectares of vineyards. All 13 classic Châteauneuf-du-Pape grape varieties are grown. Of this, 17 hectares are accounted for by the Châteauneuf du Pape Rouge, which are divided into 11 plots. In the "Les Bosquets" parcel, which is just over one hectare in size, vines over 80 years old are cultivated; the average age of the vines is 60 years. There is also one hectare for Châteauneuf du Pape Blanc and six hectares for the "Plan Pégau" vin de table. For the red Châteauneuf du Pape, the un-grained grapes are macerated for two to three weeks in traditional concrete tanks. The wine then matures in large and small wooden barrels for at least 18 months. Only then does the assemblage with 80% Grenache Noir ( Garnacha Tinta ), such as Syrah, Mourvèdre ( Monastrell ) and all other approved grape varieties. The white Châreauneuf du Pape is made from 60% Grenache Blanc ( Garnacha Blanca ), 20% Clairette, 10% Bourboulenc and 10% Roussanne blended and aged for six months in old oak barrels. Other CdP red wines are produced under the names Cuvée Laurence, Cuvée Justine, Cuvée Maxime and Cuvée Réservée.
