When I was young the only coffee my parents drank was a weak instant so I didn't taste real, ground coffee until I'd left home and the first was a cup of real Turkish coffee brewed by the family of a fellow student. Do you remember yours?
I don't remember my first real coffee but I remember that when I first tasted it, I was like "mmm, what a muck"? since I was used to instant coffee from childhood
I think I was that lucky person who tried his/her real coffee at the time she actually began drinking coffee. I was fortunate enough to have only good coffee around.
