Might want to refresh your reading on this. AFAIK this is reference to one (unpublished) study where undergrad wine science students tended to choose from a list of descriptive terms usually associated with red wine to refer to dyed white wine, most of the time.
It's certainly true that suggestion can change ones perception of wine (or any flavor), but I don't think it's clear that it's the primary factor.
Yes, this is correct —- it’s actually a fascinating study, but the translation from French was done poorly and then the English-speaking media ran with the clickbait version.
The original study finds that the terms we use for flavor (partly) encode the tuple of flavor and color. That is, given two identical smelling / tasting liquids, subjects will pick different vocabulary to describe the flavor when the liquid is red vs clear.
There's evidence that wine judging is less objective than most people involved in it seem to believe. I'm not sure that justifies calling it nonsense, or misrepresenting a study as showing that experienced people can't even distinguish white from red.
It does actually, but that wasn't really my point in referring to it. More that the GP post misrepresenting the study isn't justified by other evidence of a lack of rigour in the field.
