I've been at wine tastings where the sommelier who is a sommelier teacher can pick from what exact bordeaux region a certain wine is from without looking at the label. Respects that expert skill different from computers but mastery. I think it is like in all fields there are self proclaimed experts and real experts and not all who claim to be an expert are one some fake it. However its also been proven that people think that an expensive wine tastes better than a cheap one. So psychology and expectations play a big role. I would advocate that we get mass spectrometers out there in smart phones so that we can scan the wine and tell its contents. Not only do we want to test the wine contents, we also want to scan our meat to check that it is what is says it is and we also want to scan vegetables for pesticide residue.
