Sommelier is one of the prestigious professions.

Becoming a sommelier is considered very prestigious. This requires a lot of time and hard work. But "wine critics" are ordinary people, and they can be deceived like any other person.

In 2001, a researcher from the University of Bordeaux conducted a test on 54 students studying winemaking. The researcher offered the students two glasses of wine, one with red and one with white. After a sip of wine, the subjects were asked to describe the taste of each wine. All of them painted a bouquet and grape varieties, from which the wine was made.

The problem was only one thing: in fact, they did not drink red wine at all (the researcher simply secretly colored a bottle of white wine with a red food color). A similar test was conducted at the California Institute of Technology. Researchers in advance poured cheap wine into expensive bottles and expensive wine into bottles of cheap wine. Subjects claimed that cheap wine tastes better.
