Gelato
How is gelato different from ice cream?
Put a scoop of gelato beside a scoop of ice cream and they can look like the same thing. They aren't, and the difference has nothing to do with one being fancier. Gelato is churned slower and served warmer.
How much fat and air each one has
Two things separate them and both happen in the machine.
Air comes first. Every frozen dessert has air beaten into it while it churns. The trade word for it is overrun, and it's measured as the share of the finished volume that is air. Ice cream is churned fast and can carry a lot. Gelato is churned slowly and carries much less. That's why a gelato tub feels heavy for its size and a cheap ice cream tub feels like nothing.
Fat comes second. Gelato is built on a milk-heavy base. Ice cream leans on cream. So gelato ends up denser and leaner at the same time: the same volume weighs more and holds less fat.
What fat does to flavour
Fat coats the tongue. Flavour carried in fat is released slowly, so it arrives late and stays after you've swallowed. That's the round, lingering quality people mean when they say creamy.
Take the fat out and the flavour has less to hold onto. It arrives faster, reads sharper and leaves sooner. That's why a good pistachio gelato tastes overwhelmingly of pistachio, and a good vanilla ice cream keeps tasting of vanilla.
Neither is better. They answer different questions.
Why gelato is served warmer
Cold numbs the tongue. Taste receptors work slower the colder the food is, so the same recipe tastes weaker straight from the freezer than it does a few minutes later.
A domestic freezer sits around minus 18. Ice cream is built for that: the fat and the air keep it soft enough to get a spoon into.
Gelato is denser and leaner, so at minus 18 it's close to solid and you'd taste very little of it. Cabinets hold it warmer, closer to minus 12, which is soft enough to scoop and warm enough to taste. That's the same reason it goes soft within minutes of leaving the cabinet, and the reason ice cream survives a tram.
Which of the two names is regulated
Ice cream is a defined food in Australia. Standard 2.5.6 says anything sold under that name has to hold at least 100 g of milk fat per kilogram and 168 g of food solids per litre. Gelato is not in the Food Standards Code. The word does not appear in it once.
So gelato describes a style, and it sets no minimum. Most of what gets sold here is made carefully anyway. The real difference is that one of the two words carries a legal floor and the other carries a tradition.
Which one suits how you eat it
Gelato is meant to be eaten where it was made. It is softer and leaner, so it starts changing the moment it leaves the cabinet, and it never quite comes back.
Ice cream is for the freezer at home. It holds its texture, it survives the trip, and it's still good twenty minutes after you take it out.
Ours is the second kind. A 120 mL cup, real dairy, real cream, real sugar.

Common questions
Is gelato healthier than ice cream?
Not automatically. Gelato usually carries less fat, but it also carries less air, so the same volume holds more of everything else, sugar included. Per serve is the useful comparison here, since per 100 g hides the difference in density.
Why is gelato served warmer than ice cream?
Cold numbs the palate, and at gelato density the warmer serve is what lets the flavour come through at all.
Is Helado gelato or ice cream?
Ice cream. A 120 mL single serve made with real dairy, real cream and real sugar, built to hold its texture away from a counter.
