This is kind of a cool study.

Oh noes!

I don't think the so called wine tasting experts fair too well either.

I read about a sighted wine test where there was a white with food dye in it, and it was described as a red.

I saw that too. Was some show/documentary on tv some time ago.

I've done blind wine tastings. Those are just as fun as the blind audio auditions.
Doubly fun is doing them together, though i recommend starting the audio run BEFORE you get too much into the wine run.
