One thing I know, though, is that I am getting sick and tired of the "tinted the white wine red and fooled them all" anecdote as it has very little substance.
Any wine, white or red, can express a huge range of flavor and texture, etc., and there is absolutely no reason to suspect a "red" wine is actually a white wine. You'll note that the study does not indicate the testers thought it was a great red wine, or any particular red wine - just that they did not question it was red. That's not nearly the indictment it's made out to be. In fact, it's not an indictment at all.
Assigning too much value, or "enjoyment" to price ? Fair critique. Describing wines with bizarre descriptors like "asphalt" ? Fair critique. Dubious claims of "terroir" ? Fair critique.
But the "fooled them with white wine" test is meaningless.
