There’s not one ideal soil to produce a great wine. Many great wines come from completely different terroirs (granit, limestone, clay, sandstone, …). It’s not easy to understand the influences of all the natural parameters on grapes quality. However, you can feel that you need to look into all those parameters to optimise the potential of your natural heritage, the one that nobody can recreate.

You're welcome to visit our website which shows our most recent studies in different vineyards areas such as Provence, Côtes du Rhône, Beaujolais, Burgundy, Savoie and Switzerland.
