The Alaric Mountain is a region where all the geological eras are represented. It's an enormous mass of limestone, a vast reservoir for groundwaters which emerge at Fontcouverte at a temperature from 18 to 22°C.

The Las Vals vineyards are planted between 150 and 250 metres above sea level on tertiary and quaternary limestone, clay or sandstone formations which are of marine, river or lake origins on the high plateau.

The average temperature is from 13 to 14°C with important variations (+40 to -12°C).

Rainfall in autumn or spring average about 550mm per year over the last 34 years.

There are few days without any wind!

There is an alternance of a dominating dry north wind called Cers, sometimes quite violent, and a humid easterly wind called Marin, generally bringing with it rain.
