The followup doco is even better - the newly minted master sommeliers proceed to contradict each other, and seem to have a lot more fun than the first one.
i like the 2nd one also. in the first one they were basically college kids, like gradschool aged, in the 2nd one they are adult professionals, very close to 30 if not over. good perspective on growth. and they all have very different opinions on things which is nice. surprisingly, none of them are snobby, just very knowledgeable.
