Sommeliers are a scam
It is patently obvious. It would be funny if people were smart enough to not get taken in by this nonsense. "This wine tastes like new tennis balls." That's great, no really, I'm sure lots of talent and diligent study went into that statement. Okay, unless there actually are new tennis balls in that wine, while appreciated, that assessment is entirely unnecessary. And these clowns get paid big money to say stuff like this? Also you might have noticed that none of the master sommeliers or candidates seems particularly bright. So how hard could this test possibly be?
