Thanks for your question.
Joel 1:5 "Awake, ye drunkards, and weep; and howl, all ye drinkers of wine, because of the new wine; for it is cut off from your mouth." (Drunkards don't drink juice!)
Mt 9:17 "Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved." (They burst because the old wine that was previously in the skins (not glass bottles) had stretched the skins due to the fermentation process. To fill up the already stretched skins with new wine would burst the skins because they could not stretch further to accommodate the fermentation of the new wine.)
Acts 2:13-15 "Others mocking said, These men are full of new wine. But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: For these are not drunken, as ye suppose, seeing it is but the third hour of the day." (Peter, on the day of Pentecost, is accused of being drunk with "new wine" so clearly even this beverage has alcohol content.)
In ancient times grape juice was produced to make wine. It was rarely drunk before it was fermented. Access to non-alcoholic juice would have been limited to those with vineyards or who lived near a vineyard. New wine was alcoholic wine which had not had a chance to age properly.
Usually, when people ask this question, they want to know whether the Bible prohibits the drinking of alcoholic beverages. It does not. In fact, wine is considered to be a blessing - Deuteronomy 7:13; 33:28; Psalm 104:15; Proverbs 3:10; John 2:3-10; 1 Timothy 5:23; Ephesians 5:18. However, the Bible does condemn drunkenness - Proverbs 23:21; Romans 13:13; 1 Corinthians 6:10; Galatians 5:21. Although hard liquor [AV "strong drink"] is not forbidden, there are ample warnings against its dangers. Passages such as Deuteronomy 14:26 indicates that drinking "strong drink" is not wrong in itself but the warnings against over-indulgence are clear. See Proverbs 20:1; Isaiah 5:11,22; 28:7.
