The varietals used for Hemera come from a plateau, called le « Causse », at an elevation of 370 m, just beneath the Causse du Larzac. Lots of stones, regular strong winds and cool nights make the conditions for spicy and strong wines. The vineyards are at the upper limit of wine growing in the area.
Two main varietals can be found on the estate : Syrah and Grenache, plus a small acreage of Carignan and Mourvèdre.
The Estate works according to biodynamic principles and is Ecocert certified.
