I'm guessing that it's either a flavored homebrewed beer or a wine. The distillation process is not typically something one would want in the basement, (smelly and a potential firebomb) and I'm thinking a regular house in Baltimore might be a tad urban for the process.
A small brandy still might be do-able in the back yard but I'd store the product in something smaller than a jug.
If it's a distilled liquor it's probably as drinkable as it was when it was bottled. If it's either beer or a wine, if the alcohol content is high enough, it's probably technically drinkable but I'd smell it real careful first. Might be vinegar or something nastier.
