It's clear that Jessica is a big fan of whiskey (one of the titles even references it), and in episode 3, she buys a bottle of the good stuff to ease his ills. The brand she settles on is called Wild Fowl (it's seen throughout the show littered around her apartment too), a Marvel universe take on real world brand Wild Turkey (which oddly also seems to appear in an early episode). That in itself is a nice little gag, but the brand actually already exists in Marvel films, having appeared in The Punisher in 2004.
