: Here is a possibility. In an article "Coffee Lore" in the PEF Quarterly of July 1905 (p. 258) I read "When the use of wine was prohibited, its place was taken by a decoction of coffee-berries. The name "coffee" is derived from the Arabic Kahweh (pronounced Kahveh by the Turks), and, in its primary sense, denoted wine or other intoxicating liquors."  Lynch in his Narrative (p243) also records kahweh as once meaning wine.
