Ice cream in Italy - what is it?

[LittleFiendSusan]

Currently in Italy and enjoying the ice cream. I prefer the fruity ones but they're not creamy like the ice cream I know from home nor grainy like sorbet.
What are they and how are they made? Can anyone enlighten me?

Gelato - made differently from ice cream, the name can refer to anything frozen but the type you’re talking about is what would be typically known as gelato!

Gelato or semifreddo, both too bloody gorgeous.

Thanks @babblingbumblingbandofbaboons so according to wiki, it's the air content that makes it what it is.
But how do they make it seem not dairy tasting-last night I had pink grapefruit and lemon gelato but didn't seem dairy based at all.

Sorbetto?

Gelato is normally made with skimmed milk, so the typical dairy 'creamy' taste isn't there.
