Legend has it that this property's soils contain gemstones which account for its golden hue. It was founded and owned by the Vigneau family for several generations, beginning in the early 17th century, and then purchased by Madame de Rayne in 1834. It was her great-nephew Albert de Pontac, of the renowned winemaking Pontac family, that renamed the estate after her in 1867. In 2004, the estate was acquired by CA Grands Crus, a subsidiary of the Groupe Crédit Agricole.
Located in the commune of Bommes on a magnificent gravelly rise overlooking Sauternes, this property is the third highest point in the region, and potentially capable of producing one of the very finest Sauternes. Although it has not usually achieved this, the style here has always been to make a wine of elegance and drinkability, not overly liquourous, and one that is fairly priced.
There are 84 hectares of vines, located in a single block on Garonne gravel over clay, and with an average age of 30 years. After all of the grapes have been harvested by hand they undergo a strict sorting process, before being barrel fermented, which is the custom in Sauternes.
Typically, the wine is a blend of 80% semillon and 20% sauvignon, which ages for 12 to 18 months in oak, 40% of it new. Though lighter than some of its neighbours, its wines age well, and can be enjoyed for four to 30 years.
