"Some juice, please."

Translation: Um pouco de suco, por favor.

"Um pouco de sumo" está correto????? I don't agree

[Paulenrique]

It's correct in Portugal.

why is this not "do suco"

[Endverbraucher]

"Um suco, por favor" is not accepted even though in another exercise, it is. "Eu gostaria que você me trouxesse um suco" is translated as "I would like you to bring me SOME juice.

So, why is it not accepted here?
