Wine is alcoholic, so if you really are serious about never drinking alcohol, then drinking wine would be breaking that pledge. Wine might be a "finer," more "cultivated" form of alcohol, but it's still alcohol.
I suppose the question is more why you don't want to drink alcohol. If it's because you don't want to get drunk, then you're probably not going to get drunk off a single glass of wine.
Personally, I don't drink alcohol at all -- not because of any principles or anything, but because I just don't like it. I'll admit I can't stand the taste of wine at all... I find it too sour and acidic.

Wine is not fundamentally different from beer and "strong drinks". All alcoholic beverages come from yeast eating sugar and pooping ethyl alcohol. The question is, where does the sugar come from? With wine, it's grape juice. With beer, it's barley malt. Various hard liquors start with different sources. Tequila is made with agave while rum is made from sugar cane, for example. What makes wine so special? (That's not rhetorical… I actually am curious why you think so.)
