Bosc's vineyard is located all around the castle, thus it is easily accessible by the visitors. If you walk along the tower alley you will find explanatory boards about the vineyard and the grapes : grenache and syrah.

You can also find explanations about the typical and exceptional stony terroir of Signargues (similar to Châteauneuf-du-Pape).

The organic culture and the values of the chateau are also mentioned.

 

The exceptional terroir is made of rolled stones left by the Rhone river. Before the last geological change our plateau was part of the river's bed.

 

As you can see the tillage is extremely complicated for men and machines.
