Quick Answer
Pule, a Serbian cheese, is famously expensive because it’s made from donkey milk. Donkeys yield very little milk, and it’s tricky to process, making it incredibly rare. This highlights how unusual ingredients and difficult production, not just popularity, can lead to a cheese costing a fortune.
In a hurry? TL;DR
- 1Pule, a Serbian cheese, costs over £800/kg due to using rare Balkan donkey milk.
- 2Producing 1kg of Pule requires 25 litres of donkey milk and goat milk blend.
- 3Donkey milk's low casein content makes it hard to coagulate into cheese.
- 4Pule production involves meticulous hand-milking and a secret process with goat milk.
- 5The cheese is naturally smoked to achieve its unique texture and delicate flavor.
- 6Pule's extreme cost highlights value derived from biological scarcity and inefficient production.
Why It Matters
It's surprising that a cheese made from donkey milk is so expensive because donkey milk is naturally difficult to turn into cheese.
Pule is a rare Serbian cheese crafted from the milk of Balkan donkeys, commanding prices upwards of £800 per kilogram. Its status as the world’s most expensive cheese stems from a combination of scarce supply, manual labor, and a biological quirk that makes donkey milk notoriously difficult to coagulate.
- Origin: Zasavica Special Nature Reserve, Serbia
- Price: Approximately £800 to £1,000 per kilogram
- Milk Composition: 60 percent Balkan donkey milk, 40 percent goat milk
- Yield: 25 litres of milk are required to produce just 1 kilogram of cheese
- Production: Hand-milked three times a day
Why It Matters: Pule represents the ultimate intersection of biodiversity and luxury, proving that value is often derived from biological inefficiency rather than simple demand.
The Zasavica Monopoly
Deep within the Zasavica Special Nature Reserve in north-central Serbia, a small herd of roughly 200 Balkan donkeys produces the rarest dairy product on Earth. Unlike cows, which have been bred over millennia for high milk yields, these donkeys are a vulnerable breed with a very limited output.
A single donkey produces less than two litres of milk per day, and only when the foal is present. Compared to a Holstein cow, which can produce 30 litres daily, the scale of production is microscopic.
The Chemistry of the Crunch
The primary hurdle in making Pule is not just the rarity of the milk, but its chemical composition. Donkey milk is remarkably low in casein, the protein responsible for curdling in traditional cheesemaking.
For decades, experts believed it was physically impossible to turn 100 percent donkey milk into cheese without it remaining a liquid mess. Slobodan Simic, the founder of the Zasavica reserve solution, eventually bypassed this by using a secret process involving the addition of goat milk to provide the necessary structure.
Unlike mass-produced cheddar, which relies on industrial rennet and mechanical agitation, Pule is the result of a precise, low-yield craft. According to records from the Zasavica Reserve, the cheese is smoked naturally, which helps preserve the delicate, slightly sweet profile of the milk while adding the necessary firmness for slicing.
Why Donkey Milk?
Beyond its scarcity, the milk used in Pule is historically prized for its proximity to human breast milk. It is exceptionally high in Vitamin C—containing roughly 60 times the amount found in cow milk—and is naturally low in fat.
Legend suggests that Cleopatra bathed in donkey milk to preserve her skin, requiring a stable of 700 donkeys to maintain her routine. While modern consumers generally prefer to eat it, the nutritional profile contributes to the aura of a superfood that justifies its four-figure price tag.
Practical Realities: Buying and Tasting
You cannot find Pule at a local deli or even most high-end London grocers. It is produced almost exclusively on commission or sold in tiny 50-gram packages directly from the reserve.
- Texture: Crumbly and somewhat similar to Spanish Manchego but with a lighter mouthfeel.
- Flavour: Nutty, earthy, and notably salty, despite no heavy salt brine being used.
- Usage: Typically served as a standalone tasting experience rather than an ingredient in a dish.
Interesting Connections
- Historical Precedent: Pope Francis was reportedly fed donkey milk as a child in Argentina because of its digestibility compared to cow milk.
- Cosmetic Links: The high lactose content makes donkey milk a popular ingredient in luxury soaps and anti-ageing creams.
- Etymology: The word Pule actually means foal in Serbian, a nod to the young animals that necessitate the milking process.
Is Pule 100 percent donkey milk?
No. Because donkey milk lacks the protein required to coagulate on its own, Pule is a blend. The standard recipe is 60 percent donkey milk and 40 percent goat milk, which provides the structural integrity needed for aging.
Why is it so much more expensive than Wagyu beef or Truffles?
While truffles must be foraged and Wagyu requires specific diets, Pule requires manual labor that cannot be automated. Each donkey must be hand-milked three times a day because they do not respond well to mechanical milking machines.
Can you buy it online?
Occasionally, but usually only through the Zasavica Nature Reserve's official channels. Most people who taste it do so by visiting the farm in Serbia or at exclusive charity auctions.
Key Takeaways
- Scarcity: Only 200 Balkan donkeys exist in the Zasavica herd, creating a natural cap on production.
- Labor-Intensive: The lack of automation in milking and the secret coagulation process add significant overhead.
- Conservation: Every purchase of Pule effectively funds the preservation of a rural Serbian ecosystem.
- Nutritional Value: The milk is a rich source of Vitamin C and behaves more like human milk than any other animal dairy.
The price of Pule is not a marketing gimmick; it is a mathematical necessity of working with an animal that refuses to be industrialised. Drawing a comparison to other luxury goods, Pule is the haute couture of the dairy world—hand-stitched, rare, and priced for its impossibility.
