Poor or sour wine, the produce of the second or acetous fermentation of vinous liquors. The term sometimes designates a thin, sour wine, much used by laborers and by the Roman soldiers, Numbers 6:3 Ruth 2:14 2 Chronicles 2:10 John 19:29. See GALL. In other places it denotes the common sharp vinegar, which furnished the wise man with two significant illustrations, Proverbs 10:26 25:20.
