I started consuming coffee when I was in the high school(16-17yo), because here in Bulgaria it is not common for the younger kids to consume coffee. The general thought is that caffeine is quite harmful for the young people, so it’s better to start drinking coffee not before 15 yo.
But… I remember that in my family there used to be an old manual coffee grinder just like this one…
I liked to grind the coffee for my parents… and now I have quite the superior grinder, and I sometimes recall the old childish habits of grinding my parents’ coffee. Now one of my sons enjoys grinding coffee a lot too and whenever I forget to give him the honor, he feels really sad… 😁
