13.5% is the mid-range level of alcohol in wine, so what a ingenious name for a wine bar... Baltimore’s 13.5% Wine Bar is in Hampden, a neighborhood not normally known for fine wine, but gentrifying enough in recent years that the bar now fits right in. They offer over 40 wines by the glass, as well as over 200 wines by the bottle and a menu of lite fare and entrees to tempt the taste buds.
