Vineyards and wine production are the main local industry.
The Languedoc region, formerly famous for "Cooperative" plonk, now produces mainly quite drinkable wines. You can visit domains to taste, and buy, wines, including a bottle or two for the designated driver to enjoy on The Balcony later, or to be shipped directly to your home. In late Spring some vineyards offer a Wine Walk of their vines, when the French will carefully inspect the growth, and taste samples of wine from other years from those vines which are set out under a handy tree, before buying "en primeur" for delivery the following spring when the wine has been made.
A few vineyards may allow you to help with the harvest in the Autumn, which is also great fun.
