Terrasses du Larzac Geology

I posted a map of the Terrasses du Larzac appellation in an earlier post here. Thanks to Languedoc Wines on Facebook I recently came across this fascinating video (in English) on how the Terrasses du Larzac were formed. It features Charles-Walter Pacaud of La Croix Chaptal, a domaine in the tiny hamlet of Cambous at the southern end of the Terrasses - the stepped plateaus that Charles-Walter explains and points out in the video.
