"Which wine is expensive?"
Translation:어느 와인이 비쌉니까?
It's true you can reorder pieces of a sentence around but in Korean, just like in English, determiners (e.g. "that" in "that dog", "this" in "this car", "a" in "a cat", "which" in "which car", "what" in "what bread", etc.) always affect the noun that immediately follows. In English "car this" does not mean "this car", "bread what" does not mean "what bread", "car which" does not mean "which car", and so on. The same is true in Korean. 어느 always precedes the noun it affects so you need to keep it before the noun it affects.
Here's a more Illustrative example:
무슨 차 - what tea (무슨 is a determiner, just like 어느)
그 여자 - that woman
좋아해요 - like
그 여자가 무슨 차를 좋아해요? - What tea does that woman like?
The subject and object can be switched around to write 무슨 차를 그 여자가 좋아해요? and mean the same but notice that the subject is not 여자 but rather 그 여자. Likewise the object is not 차를 but rather 무슨 차를.
So what happens when we switch determiners? This happens:
무슨 여자가 그 차를 좋아해요? - What woman likes that tea?
Note how the subject is now 무슨 여자가 instead of 그 여자가 and the object is now 그 차를 instead of 무슨 차를. So this question is not the same as the previous one.
The answer you actually wrote is not grammatical in Korean as 어느 is not affecting a noun.
