I think that's implied by the 还是 in that two options given. I think if you dropped the 'do you' structure that makes the English an explicit question and said "you like white wine or red" it would still be taken as a question for the same reason.
In English, we usually put the short word first in a pair. So I've reported that "Do you like red or white wine?" should be accepted. Yes the Chinese puts the colours in a different order, it's just euphony. (Same for 'man and woman', 'salt and pepper' etc. )
