Chateau De Goulaine, France
Est. 1000
This is the oldest family-owned business and continuously-operating winery in Europe. They started producing wine in the year 1000, and has been in the Goulaine family all along, minus a short period of time during the French Revolution, where it was sold to a Dutch banker to prevent it from being looted and destroyed.
The Goulaine family reacquired the business in 1858 and expanded their operations, producing a variety of wines including a Muscadet and Sancerre. The grounds currently house a biscuit museum and butterfly aviary, as well as the wine-making infrastructure.
