Yes, Oenologists assumed that the wine which was red was actually... red wine. This study is always quoted and is a sham IMO. What this is saying more than anything is "the placebo affect does work." which is totally true.
But IMO it doesn't say a whole lot about wine tasting being BS.
It's the kind of information that's a bit too upsetting though, even for non connoisseurs to want to accept.
This "study" has no value. I can certainly distinguish between the average $10 bottle and $50 bottle.
Actually the study does have a value: It induces people to think there are no differences between wines and keeps the prices for the good stuff lower. So please continue to post it.
What's your basis for making this silly assertion? These were Oenology students. It's not like they pulled random students off campus.
They should probably be using $200 equalizers to get that, not buying $10000 components where more than half of them couldn't possibly change the sound.
Well for one thing, that's wrong- distinguishing wine is easy. Even people who are just pretty into wine can identify different vinyards etc. and actual sommeliers can nail wine down to the year it was bottled and the conditions it was stored[1].
The thing you're referring to is that when you line up regular people and give them $5 and $1000 bottles of wine, they will rank them in essentially random order. That should be no surprise at all. People have their own favorites. When you line up experts, they can differentiate cheap wine from expensive wine, but inside a broad category (say $200-$1000) they will rank essentially randomly. Again, that shouldn't be surprising at all, because "quality" itself isn't what's being paid for or looked for. Each wine is developed for a taste, not for some abstract quality metric that is the exact same for every wine.
Normal audiophiles will typically aim for objective metrics like THD, but the extreme guys are often aiming for subjective/vague things like timbre, color and soundstage. That leads to some esotericism. They also tend to have gobs of money to throw at this stuff, so a $1000 knob may be more about getting exactly what you want, or even just prestige. Both rational choices. Regardless, its inherently way more absurd than wine because even audiophiles with the most virgin ears will get nothing from .001% THD (very high end) vs <.0001% THD (verging on a lab setup), and virtually all will get nothing from <.01% THD. On the other hand, wine fanatics who have found their favorite wine will be able to recognize it quite accurately.
