White grapes on the left (probably sauvignon) and red grapes on the right (I don't know which).
Here and there you can also find, if you know what you're looking for, local grapes like grolleau and pineau d'aunis. They're grown in lesser quantity and are used mostly for blending, although the pineau d'aunis makes an excellent dry rosé which is one of my favorite wines.
From a distance, you can clearly see the transition from one varietal to another.
Throwback Thursday has taken today off.
