Tracing the world’s oldest cheese is challenging, but direct evidence shows that humans have been consuming milk for millennia.
Archaeologists have discovered milk residues in ancient pottery from various locations worldwide.
Research on carbon isotopes of fatty acids from pot residues reveals that humans have been consuming milk in the UK since 4000 BC. However, in Anatolia, a region in Türkiye noted for its Neolithic agriculture, evidence suggests milk consumption dates back even earlier to around 7000 BC.
Farmers in Anatolia were widely mobile. Although milk fat residues often degrade over thousands of years underground, the sheer number of ceramic pieces found leads scientists to speculate that these early peoples were likely producing long-lasting dairy products like cheese.
When milk is transformed into cheese, lactose levels decrease, helping to mitigate lactose intolerance, which was common across Europe. It wasn’t until approximately 3,000 years ago that genetic mutations became prevalent, enabling adults to produce lactase.
A 2023 study from York University found protein structures in a Polish late Neolithic pot, suggesting it contained cheese made from the milk of cows, goats, and sheep.
The oldest cheese sample still known today is approximately 3,500 years old and was found around the neck of a Bronze Age mummy in the Xiaohe Cemetery in northwestern China.
A team at the Chinese Academy of Sciences conducted an analysis of this specimen, identifying it as kefir cheese (fermented bacterial milk). The scientists found DNA from various bacteria and yeast species, including Lactobacillus kefiranofaciens and Pichia kudriavzevii, which are present in kefir today.
They hypothesize that the lump could represent a kefir starter grain, a concentrated bacterial colony used to initiate cheese fermentation. These grains were likely regarded as valuable offerings for the afterlife in ancient times.
