A week after Bastille Day, the summer heat was at its peak. The rosy tan stucco on the houses matched the scorched soil, a shade lighter than their terra cotta rooftops. Their large shutters shielded them from the sun’s onslaught, and spoke of a time before air conditioners. It was a traditional, agricultural region still. Orchards of peaches and apricots, olives and grapes; this was the terroir of Cotes du Rhone, and the famous Tain l’Hermitage vineyards. Gardens burst with bougainvillea, hibiscus and oleander.
