One litre of the milk costs £29 and 25 litres are needed for cheese

If you're going to splash out £700 on a kilogramme of cheese, you want it to be very special.

And these dairy farmers in Serbia are certainly offering an usual experience for their pricey cheese, named Pule.

Retailing at €1,000 (£734) per kilogram (2.2lbs), the cheese is made with donkey’s milk and can only be found at Zasavica Nature Reserve, in Serbia.

One litre of the donkey's milk costs €40 (£29) and each kilogram of cheese needs around 25 litres of milk

Manager Slobodan Simic creates the cheese from 140 donkeys at the reserve, with only around 12 producing milk at any time.

He said: ‘What is particularly exclusive is that in the whole world only we were able to make and produce donkey cheese.’

Donkey's milk is believed to have medicinal benefits because it is similar in composition to that of humans.

It also contains an anti-allergenic, is low in fat and has 60 times more vitamin C than cow's milk.

The main reason for why the cheese is so expensive however is because it is very rare and its production results in very high costs.

One litre of donkey's milk costs €40 (£29) and each kilogram of cheese needs around 25 litres of milk.

Slobodan said: ‘This is the most expensive cheese in the world, costing 1,000 euros a kilogram, and it is on all the world first lists by price and by rarity.

‘So, the one thing is that it is the most expensive, and the other one is that it is produced only here, on the Zasavica farm.’
