That's an interesting point, although the ancient Greeks only ever drank diluted wine, and they did believe that you could die from drinking wine at full strength. Undiluted wine was given to the helots so that their drunkenness served as a warning to the spartiates, and the death of one of the Spartan kings was partially attributed to madness caused by drinking undiluted wine, a habit which he picked up from the barbarians (although I admit that particular episode lends itself to many different interpretations).
