By the way, I have a question regarding "Do you want to drink coffee" and "Do you drink coffee".

I always thought that the former sentence stands for "コーヒーを飲みたいですか。" and the latter stands for "コーヒーをのむんですか。" - but "コーヒーをのむんですか。" can also mean "Do you want to drink coffee" (if I am not wrong) apparently.

So can someone explain to me the exact way to say "Do you want to drink coffee" and "Do you drink coffee"?
