Alcohol is one of the strongest elements with which we can learn about a person's personal characteristics. Make no mistake. Here we are talking about the stage before drunkenness, because at that point it doesn't matter what went into the stomach anyway, the masks have fallen, so there is no difference between whiskey and cheap wine. When we are drunk we are all "the same", regardless of what we drink. But the introduction to the peeling of the personality is already the choice of drink, and already in the glass or bottle your character is reflected.
