I don't recognise that at all and think you are chasing a stereotype. There is a choice of 3 red and 3 white. Since VS improved the UC meal service, the crew has been noticeably more informed about the wines and it's not uncommon to find that the crew have tasted them (not in-flight!) and can pronounce the names reasonably confidently. I contrast that with an experience in BA F where the crew-member said "I'm not even going to try to say that!" (The word was "frangipane".)

The real criticism of VS is that the wines themselves are pretty dire. But the service usually isn't.
