I'm always a bit put off by the "experts can't tell the difference between these two things!", in this case red and white wine. On closer inspection one usually finds an element of deception, here the white wine is coloured red and then experts describe it as a red on tasting.

This makes sense from a Bayesian point if view... What are the experts priors? What's more likely? That their nose is off today or someone is trying to decieve them by dying white wine red? I would guess it's the former. There must be a large publication bias is well, "experts can differentiate white from red wine" is hardly going to get much attention.

To make this a fair trial I think you need to blindfold them rather than "trick" them.
