I'd be interested in them doing a blind taste test.
Yes, there's human interaction and other subjective factors going into what people report taste as - much like knowing whether an artist traced a photo when making art (demonstrates skill without technological assistance)
But sometimes this changes - eg Europeans initially rejecting Californian and Australian wines, then grading them well in blind tests, then accepting them more (with some hold outs for traditional regions or high prestige makers etc)
