Acts 2:13 - Ellicott's Commentary On The Whole Bible

These men are full of new wine. — Literally, of sweet drink — the word “wine” not being used — stronger and more intoxicating than the lighter and thinner wines that were ordinarily drunk. The Greek word was sometimes used, like the Latin mustum, for the unfermented grape-juice. Here, however, the context shows that wine, in the strict sense of the word, was intended, and the use of the same word in the LXX. of Job 32:19 confirms this meaning. The word for “new wine” in Matthew 9:17; Mark 2:22, is different, but there also (see Notes) fermentation is implied. The words, as has been said above (Note on Acts 2:4), point to a certain appearance of excitement in tone, manner, and words.
