"You all" or "all of you" is not necessary in English. I understand why they ask for it but it is unnatural for many. It's an irritating feature that needs to be optional. I'll continue to write it up. They've wisely made it impossible to report.
Like alejoferrando said, "wine" without the "s" should also be acceptable. In Spanish the form is plural, but in English the same meaning is generally going to be expressed using the singular, since wine is an uncountable noun.
