I also really don't like the taste of UHT milk (called "H-Milch" in German). For me it's undrinkable. I can also taste the difference in a cappuccino. Interestingly, like the_mitshuiko already said, UHT milk is not very common in Austria but extremely common in Germany. When I'm in Germany, I have a hard time finding a coffee shop that doesn't serve coffee with UHT milk. It is basically impossible and to be honest, it says a lot about the German food culture. In Austria, not even McDonald's uses UHT milk in its McCafes but in Germany, even the most expensive coffee shop with coffees for 4 € and up cheap out on the milk.

It’s a preference thing. UHT milk is not very common in Austria for normal consumption but it accounts for almost all milk sales in Austria. I’m sure some recipes take this into account. I found some pastries that explicitly called out to use UHT milk.

I don’t think either has a better taste. Lots if people also love lactose free milk which has a completely different taste.

The UHT process destroys milk proteins. I'd rather eat maturated cheese than drink UHT milk any day.

I grew to love the UHT milk in France. It does tastes a bit different, but has some upsides too.

I loved the milk but then again it was chocolate. Maybe plain tastes different. I know i despise powdered milk.
