Actually, what I think they've tested is wine snobbery, not whether there's a difference between red and white wine. That's what I meant by "bullshit". Look at the setup of their experiment. They made people say stuff about the wine they were drinking. Unsurprisingly, they found people used "red" words for wine dyed red and "white" words for un-dyed wine. This is not a surprising result. The effect is called "priming" and it has been known for a long time. It doesn't say anything about being able to taste the difference between red wine and white wine. If you do a blind folded taste test, I can guarantee you you can tell the difference. And if you happen to know red wine tends to be less acidic and more astringent than white wine, I can also guarantee you will be able to pick out which is which.
