In vino veritas

It means, of course, there is truth in wine, an observation that surely predates Rome. It means that alcohol can remove psychological and social inhibitions and allow people to say what's really on their minds, which has probably ended millions of friendships. Alcohol can make people sentimental, or violent, or sloppy, or amorous; but it can't make them bigots unless they started out that way. Too much alcohol changes behavior. It doesn't change beliefs.
