Drinking age of Europeans

My father, who is of Polish and French descent, says he had his first sip of wine at the age of 12. This was a tradition that the night before a boy’s 13th birthday he was to be allowed one glass of wine as a symbolic of good luck into entering teenage years which marked the start of independence and manhood. Forty years ago, teenage boys were allowed to work and were expected to keep good grades and help around the house. A 13 year-old boy was seen as a young adult. This understood drinking is concerning to me because some young adults could go too wild at such a young age.
