The wheels are examined by a quality control expert, who uses all five senses to examine them and evaluate whether they are worthy of becoming Grana Padano PDO cheese. 

The quality control expert tests each Grana Padano PDO cheese wheel to ensure that it has no defects.

To do this, he taps the rind in various places with a special small hammer.
