Tennis star Novak Djokovic will be buying the entire world’s supply of a rare cheese. The cheese, you may ask? Donkey cheese. This purchase has nothing to do with his gluten-free diet. From the story that has come out, this move is more of a business dealing for his restaurants. The cheese is called pule and is expensive. One pound of this donkey cheese is between $500-600. The cheese is produced in Serbia, which is where Djokovic is from. This partnership between the No. 1 tennis player in the world and local cheese farmers that produce this cheese presents a good local relationship. The farmers could, if they want, sell their cheese to the world and possibly sextuple their profits. Instead, Novak Djokovic owns all this cheese now. Basic economics here with buying low and, if he wants, sell high. For the most part, this cheese will be in food dishes at his restaurants. Expect the Travel Channel and the likes of Andrew Zimmern and Anthony Bourdain to visit the restaurant for a piece of that cheese.
