"You drink wine."
Translation:Du trinkst Wein.
If you're using 'Ihr' then the conjugation of the verb is 'trinkt' as 'Ihr' is the plural form of 'you' (i.e. You are all drinking wine). 'Trinkst' is the version that goes with the singular form of 'you' (assuming it's 'informal'). 'Ihr trinkt' or 'Du trinkst', but not 'Ihr trinkst'.
"Sie trinken Wein" is only right if you are using the formal "Sie" instead of the informal "Du". You still refer to a single person, male or female. If you were talking to a friend, it would be "Du trinkst Wein."
"They drink wine." would also be "Sie trinken Wein.", but here "Sie" is plural. It can easily be confused with the formal you (="Sie) :/
"Sie trinkt Wein." would be "She drinks wine."
"You drink wine." could also mean "Ihr trinkt Wein."
In conclusion: "You drink wine." can be translated with "Ihr trinkt Wein.", "Du trinkst Wein." or, if you are talking in a formal way, "Sie trinken Wein."
