Ambra di Talamello

Ambra di Talamello is an Italian cheese that originated in the Marche region of Italy and is produced in Talamello, Italy. 
It is a type of Formaggio di Fossa, a designation for cheeses that are aged underground. Ambra di Talamello is wrapped in cloth and then aged in pits constructed of tufa limestone, and the floors of the pits are lined with cheesecloth and hay. During the aging process, the cheese develops a mold and ferments, which gives it a sharp flavor. 
The cheese is aged for a few months, after which it obtains a golden, amber coloration.
