Weeknight Cocktail | Vampire's Bite

For some reason around the holidays people start making frou-frou drinks full of sugar that don't taste good.  Why do that when you can just make your regular drink festive?  Adding a ghoulish dripping edge to a standard vodka soda {or take it up a little with berry vodka and berry soda} makes you fun and festive, but still a grown up.  Because grown-ups drink real drinks.
