Yeah, I'm sure a lot of these tasters are overly pretentious. But some people are willing to go the opposite extreme and think people can't taste anything. Can anyone tell the difference between Coke and Sprite? Between Coke and Pepsi? Coke and Diet Coke? Of course we can. The difference between a typical pinot noir, syrah, or cabernet sauvignon is not something it takes magic powers to differentiate. Now specific years, wineries, etc, now that raises questions.
