This might actually be my favorite card thematically. I love the idea of an investigator seeing something horrifying like some Rotting Remains and just deciding "nope" and taking a swig of alcohol. And you can bust the bottle over the head of an enemy too, which is hilarious.
Tennessee Sour Mash has quickly become one of my earlier upgrades for solo Skids who has trouble with willpower treacheries. This gives him enough of a boost to either pass those scary tests or at the very least lessen the damage they do. Two uses tends to be enough unless he is particularly unlucky with encounter deck cards. The attack is also solid, granting him +3 fight and +1 damage. Combine it with Vicious Blow and suddenly you have an incredibly versatile card that is useful in a variety of situations. The upgraded version being fast is especially critical when playing solo where every action counts.
