What's wrong with kids knowing wine exists and people who like it exist? How does shielding children from knowing what wine is help them not become alcoholics? xD On the contrary, if they don't know what it is and feel like it's a forbidden topic, they would get their childish unhealthy curiosity making them do crazy things. I don't see anything wrong with this sentence. It doesn't say "Wine is good for everyone" which is wrong, it says "I like wine" which is a perfectly normal sentence.
But this is slightly off topic actually :)
