Divle obruk peyniri is made in the village of Divle in Karaman's Ayrancı district. Produced from sheep's and goat's milk by traditional methods, it is packed into lamb and kid skins and lowered into a cave the villagers call an obruk. Resting about 5 months in this natural cold store, 36 metres deep, the skins take on a reddish hue from a bacterium that lives inside.
