This week-end, have a look around and try wines. My tip is to take the train from town centre and alight at Russin, a small village surrounded by vineyards. Once up there (bit of a climb from the train station, nothing dramatic but to bare in mind if you have mobility issues), there is a "Cave" which has music, food and ample amounts of wine you can try, it's just off the village, go past the local boozer and follow the people going there.
