Thank you for your references, but you are missing the point. Neither of your link actually contradict my statement, if your read the article beyond the click bait.

Two of them are about classifying the wine from cheap to expensive, which makes no sense because the price doesn't mean the wine taste better, taste is actually subjective first of all and the price does not only depend on the taste anyway as I explained before. Giving a rank to wines or saying that they are different is actually an immense difference in term of logic.

The one about colours is not relevant either. It states that people are influenced by the colour and dismiss the odour. Being able to distinguish similar wines in taste is very difficult, regardless of the price and wine colour. It takes an expert to do it because of the shear number of flavours. Even expert can be fouled when wine are close.

I wish you had the opportunity to try a nice aged Bordeaux one day you'll get my point. For most people all bread are the same, all rice tastes the same, truth is if you are into this kind of food you are able to tell them apart.
