My pet peeve with all of those studies is who they consider as an expert. It is usually adhoc random group of enology students.
There is great video of guy trying to reconstruct red wine from whites + coloring and serving it to master of wine: https://www.youtube.com/watch?v=sN83j5ZOUm0
And there are a lot of other tricks and blind tasting sessions in his channel. This is how expert taster works.
