How Long Can you keep your Pizza Dough in the Fridge?

The answer is : It depends 

Here is a test of some dough I thought would be getting a bit funky. I made  4 dough balls on a friday night . Cooked 3 pizzas on Sat then left one in the fridge until the following WED ! That is 5 days !  I made a prosciutto Pizza on day 5. Dough was Caputo 00 flour , 60% hydration. I took it out of the fridge 2 hours before and stretch and folded it once , and shaped it into a ball about 1 hr before. 

The result : more chew than a fresher dough - but not in a bad way,  quite tasty and still had a good rise around the rim and toasted up in 2 min.
