Don't need to go in medieval time. By my parents time, adults gave "colored water" to help keep children calm at school. And the "colored" part is wine.

Also, 21 for adulthood is very american, it's lower in most part of the world. And idk for the rest of the world, but it was also even younger in medieval europe than in modern europe as there was no concept of "teenager" for common folks.
