Is port a kind of wine？thank you !

This is a better way to phrase your question : "Which products are worth buying in Spain and Portugal?"

I have visited Spain a few times.  I really like their cured meat e.g. chorizo and jamon serrano.  Rioja wine is very nice.  I also like turron, which is a nougat-like sweet.  

I have never been to Portugal but I like port.
