A natural cave beneath a hill near Divle, Türkiye, is used to mature skin-packed tulum cheese. The district describes a cool, humid seasonal store; reported cave lengths differ between official sources.

Divle Obruğu is a natural underground cavity used to mature Karaman Divle Obruğu Tulum Peyniri. The Ayrancı District Governorship places it under a hill about 1.5–2 kilometres southeast of Divle, also called Üçharman, and describes the passage as running east–west. The cave is a place-specific part of the cheese practice; it is not a cellar design that can be transferred to another site.
The local source describes the cave as a natural cold store and says a lift above the hill is used to lower and raise cheese. It reports an approximate depth of 36 metres. Its current page gives a length of about 150 metres, while a 2023 Karaman Agriculture Directorate report says about 250 metres. These differing published figures are not reconciled here.
The Ayrancı source reports an interior temperature of about 4 ± 1 °C and relative humidity of 80 ± 5% during the cheese-storage period. It says the cave reaches about +22 °C in winter, when it is empty. These values describe the local source's account of this cave; they are not a universal specification for natural caves or a claim that temperature is actively controlled.
TÜRKPATENT identifies Karaman Divle Obruğu Tulum Peyniri as a registered designation of origin, registration number 270, dated 8 December 2017. The registered geography is Ayrancı District in Karaman Province. That product designation links the cave to a named regional cheese, while this build entry focuses on the fixed natural site.
The district's description says the cheese is packed into goat or lamb skin tulum sacks and matured in the cave for five to six months. Local and cultural-heritage accounts describe a seasonal cycle, with the mature bags taken out in autumn. The Türkiye Kültür Portalı records producer, weight, type and entry date on a cave slip and in the keeper's ledger, showing that the storage is organized by batch rather than treated as anonymous cave stock.
A 2016 Anadolu Ajansı photograph shows one interior view: skin-wrapped cheeses sit on wooden racks among rough cave walls. The rack arrangement belongs to that photographed scene; neither the district page nor the product register makes it a standard plan. The linked photo remains credited to AA/Mehmet Çetin, and the source does not state a reuse licence.
The Ayrancı District Governorship calls the practice centuries-old, but the sources used here do not provide a dated first attestation. The period is therefore recorded as unknown rather than assigning a medieval or earlier date. TÜRKPATENT's 2017 registration dates legal designation, not the cave's origin.
This page describes the natural cave, its documented use and reported local conditions. A full survey, geological account or guide to entering or building an underground space is not given.
The Ayrancı District Governorship describes cheese maturation at Divle Obruğu as a tradition lasting centuries, but the sources used here give no dated first attestation. This dates no particular cave feature.
The cave is described beneath a hill 1.5–2 km southeast of Divle/Üçharman village. Official sources report different approximate lengths, both with a depth near 36 m.
