Not containing or having any wine.
The wineless dinner was a refreshing change from the usual wine pairings.
Wineless → It is formed from "wine" (from Old English *win*, meaning fermented grape juice) and "-less" (meaning without). The word "wineless" means without wine or lacking wine.
Think of being 'without' ('-less') wine ('wine') — that's what wineless means.
