The Apostolic Fathers make very little reference to wine.  Clement of Rome (died 100) said: "Seeing, therefore, that we are the portion of the Holy One, let us do all those things which pertain to holiness, avoiding all evil-speaking, all abominable and impure embraces, together with all drunkenness, seeking after change, all abominable lusts, detestable adultery, and execrable pride."

The Didache , an early Christian treatise which is generally accepted to be from the late 1st century, instructs Christians to give a portion of their wine in support of a true prophet or, if they have no prophet resident with them, to the poor.
