Most state laws, including Vermont (I would assume) label liquor as alcoholic drinks over a certain % ABV. ABV under a certain % (usually around 20/21%) are allowed to be sold in grocery stores. In Ohio, watered down liquor such as vodka, rum and even bourbon are sold on grocery shelves. Just because they are sold in grocery stores, doesn't make them wine. I think it sounds like it should be allowed, but it might not depending on the security personnel.
