Every Monday evening during summer, the lovely medieval town of Sommières organizes a festive outdoor event around wine and local products. For 4€ you get a glass that you can fill twice with the wines of your choice amongst the selection proposed by the local wine producers. You also have live music and lots of local food to buy. It gets a bit buzzy so it’s nicer to arrive early.
Sommières – Place du Marché – 19h-23h.
