The Château de Goulaine is a former castle, now a château, in the Loire Valley located near Nantes, France. This castle has been home to the family of the marquis de Goulaine for over a thousand years. Château de Goulaine is also the estate-bottled wine produced at the château.
In the 12th century, when the Duchy of Brittany was independent, the first Goulaine, Jean de Goulaine, then captain of the city of Nantes, fortified the estate, which is still surrounded by marshes, to defend against attacks from Normans. The Goulaine were of the old nobility, recorded in the Seventh Crusade (1248). During the Wars of Religion, the Goulaine fought for the Catholic League: Gabriel, sieur de Goulaine, at the head of fifty lancers, and his brother Jean, baron du Faouët, took the châteaux of Trogoff (Plouescat) and of Kérouzéré (Sibiril) in 1590. Gabriel was attached to the Bourbon cause in being made a marquis by Henry IV of France. The Goulaine family ownership of the estate continued uninterrupted until 1788 when it was sold to a Dutch banker. This circumstance helped save the château from destruction during the French Revolution. In 1858, a member of the Goulaine family reacquired the estate and maintains it today.
While it is not clear exactly when the estate vineyard started producing wine for commercial use, rather than just family consumption, the millennium during which the estate of Château de Goulaine has been producing wine makes it the oldest known wine business still in existence; It is believed to be the third oldest commercial enterprise in the world. It is considered the oldest European family owned business. The castle estate is one of the last Châteaux de la Loire to still be producing wine.
