I once visited a place where they do very regularly tasting of a lot of food and beverages. When visiting, the director told us that they had once a blind tasting between red and white wine, and that was involving some fairly seasoned wine drinkers. They could not tell red from white apart. I could not believe it, but I visited a winemaker recently in Burgundy, and asked the guy what he thought of this experiment. And he confirmed it, in a blind test, he and a lot of people can't distinguish red from white wine.
