I watched Somm several years ago. I laughed so hard at the end when the main guy that everyone said was sooooo smart and such a great taster "failed", and didn't get promoted to Master (and laughed even harder when the pre-credits revealed that he'd re-taken it the following year and "passed" - IIRC, it costs $5,000 to sit the MS exam each time).
It's all a bunch of baloney.
