When did the concept of "wine is grape juice" originate? A discussion in chat today has lead me to this question.  Most of us should be familiar with the debate about whether Jesus drank alcoholic wine, or some other form of wine, or simple grape juice.

My question isn't about settling that debate, however.  My question is essentially asking when did the debate begin?  What is the history of "Jesus only drank grape juice" interpretation?
According to this PDF, the theory comes from the idea that the current process of fermentation far exceeds the fermentation process of Jesus time, therefore the concentration of alcohol in the wine must have been so weak compared to wine today, that people started to assume it must have been like grape juice compared to the wine today.

However, the bible does talk about drunkenness, and the only way to get drunk is with alcohol so the wine described in the Bible must have had some alcohol.
