Name the Italian island known for its prisoner-produced wine

Francesco Papa, a prisoner on the penal colony, walks between rows of grapevines.

This island looks like a tourst's dream, with a lush Tuscan landscape and beautiful beaches.

But tourists are strictly prohibited. In fact, it's closed off to the public, save for supervised tours. 

That's because it's a maximum-security penal colony. The felons who reside here, though, produce some of Italy's finest wine. 

For this Geo Quiz, we're looking for the name of this Tuscan island. Can you name it?
