I've been experiencing the same thing for about three months now.  I am not and have never been much of a drinker ... but now, with even a half a teaspoon of wine or other alcoholic beverage, I immediately start hiccuping and experience the feeling of needing to burb.  I did notice, however, that I do not experience quite the same with vodka.  Can't figure it out either and I haven't seen any responses here that satisfied me.
