One with a cork and not a twist-off top. I prefer wines from Australia, myself.

can’t tell you bro am not old enough yet to drink

Buy a “classic” red like merlot, cabernet, or pinot noir, since reds age well.
Go for a bottle that has the vintage (year) on it.

Go with a nice Bordeaux made by Rothschild, If stored properly it will age to perfection in 18 year’s. Go to a good Liquor store and ask the Manager or owner to help you with that…. Congratulations on being a parent, I wish you all the best….

I’d probably go to a wine store and ask them specifically with your intentions.

Definitely go with Bordeaux . Something like Chateau cos D’estournel in St Estephe
You also need to become friends with a good wine merchant because the choices are vast and often confusing
Congratulations on becoming a father.
Btw Where are you located ?Maybe we know a wine guy in your area

Truthfully you are going to have to go for the big bucks to get a wine that will age in 18 years, if you want something that is going to be good to drink and well aged. Without going all the way up to the top range, you could try a bottle of La Consellante (sp), St. Estaphe, or any of the top line Romani Conie, which are quite expensive, but you can’t go wrong.
(please excuse the spelling). Of course, about the most expensive is Petrus, a Bordeaux, which can’t be beat.
