I vaguely remember looking into this before, and it turned out that the tasters were being told (incorrectly) that it was a red wine, and asked to describe the flavour profile. They then used tasting terms more frequently associated with reds than with whites, and didn't question what they were told.

So it's less a case of "they cannot distinguish red from white" and more a case of "they went along with a suggested classification". I feel like this is a weaker result, although it's still a little surprising.

Thanks. Together with GP's point about the possibility of weird wines, it seems reasonable that one could go along quite far on a false premise.

My feeling is there is the high level classification which is quite difficult to fuck up. After that it’s all adjectives and analogues, which is the fluffed up phoniness that inherently presents itself in the process of converting our subjective experiences of physical reality into abstract symbols.

Yeah, but that still shows people's perception of wine is barely above noise level, if it can be so easily misled.

For comparison, imagine someone showing a piece of Picasso to art critics and saying "Could you please describe the artistic significance of this painting by da Vinci?" The critics won't start using terms commonly reserved for Renaissance era; they'll say "What the fuck are you talking about, this isn't da Vinci."

Both artists are dead. It is possible to learn all of their paintings. It is not possible to learn all of the wines.

That sounds a lot weaker.

Quick, label all the US states: https://imgs.xkcd.com/comics/label_the_states.png

I've given this map to half a dozen smart/well educated Canadians, who happily engaged in pointing out the states they recognized for several minutes, and not one of them noticed until it was pointed out.

I suspect it would work nearly as well on many Americans.

What’s the joke? Looks normal. I see Thirdmont. Indiantwo. Yep, ordinary map.

So? That's focusing on what they know and not having time to notice the extra. Different from making incorrect statements

For anyone else who is geographically challenged, the map apparently has 64 states instead of 50. Here is an article with the extra states highlighted.

I'm from the UK and would probably have fallen for this for several minutes as well. I hope that I'd eventually realise from the number of states down the West coast.

A lot of the biggest perceived differences come from temperature, since red wines are usually served at room-temperature. If you ever decide to do a blind test, make sure to control for temperature. I did it, and I had a very hard time picking out which varietals were red and which were white.
