I somewhat remember my parents offering me a drink to try out when I was 6 or 7. Not sure if it's a made up hint of memory.

It definitely wasn't something frequent or high dosage though.

I actively started drinking with peers around the age of 12 - 14. That was in secrecy from parents though, asking homeless to buy us the goods.

My parents definitely offered me alcohol when I was a child. The hard alcohol was mostly to show me how it burns the throat and not to try it, while beer was bitter but okay for a sip or two to feel grownup. Alcohol also had a medicinal use in the family, though I'm not sure about the medicinal effect.

After I was 14 and more, alcohol was introduced on more regular bases, but not with social pressure to drink, just was available as an option.

Decades later, I'm just a social drinker.

I had essentially the same experience. I'm 67 now. My grandmother used to give me a miniature of De Kuyper's Cherry Brandy for Christmas from when I was six or seven, I made it last until after New Year!
