Many lavender distilleries are scattered about the countryside surrounding Valensole. We saw a few just on our drive into town, up the valley from Gréoux.
We were told that one of the Valensole distilleries is the only one left [in the region?] that still uses the classic method: separating the flowers from the stalks, using the stalks to fuel the furnace and cooking the flowers - rather than throwing everything together into an hermetic pressure-cooker type of still. The Office de Tourisme was closed on Sunday, where we had hoped to get more information on this.
