Novak Djokovic: No. 1 in tennis, king of donkey cheese

The jokes write themselves on an item like this: Novak Djokovic, world No. 1 and a budding restaurateur in his native Serbia, has seized the lump sum when it comes to, of all things, the world's supply of high-end donkey cheese. It is called pule, and among its other traits, is said to have 60 times as much Vitamin C as that from any given bovine. Labor intensive, 25 liters are required to produce one kilogram of cheese. The Zasavica farm where this cheese is produced shares a name with its location, Zasavica, Serbia.

This begs two questions: Just who is milking these donkeys? And is Djokovic trying to trump Roger Federer's connections to that other heralded flavor, Swiss cheese?  
The best excerpt from the write-up linked above: <em>"The reserve also produces bottled donkeys' milk, which is said to have been a beauty secret of Cleopatra. ... The legendary Egyptian queen was famously said to have bathed daily in asses' milk, and the Serbian company offers a soap bar made from donkey milk for those who can't afford a bath of the stuff."</em>  
Say what you will, Djokovic is revealing himself to be a shrewdly enterprising man.
