Do you have any suggestions for different types of liquor i can substitute?
Looks like you go for stronger alcohol, so might as well throw in some rum and absinthe, maybe tequila too. Soju, sake, and baijiiu are pretty trendy these days, although I don't know if you'd like their flavor & proof, same goes for hard seltzers in place of the dinner beer.
Tbh there's a ton of variety you could get within just whisky and beer without needing to go for other alcohols. If you enjoy whiskey that much, might as well swap out that Busch Light for craft stouts. And if you're on that Tennessee/Kentucky border, I mean, you've definitely got a bunch of bourbon and rye whiskey to tide you over before you even have to start thinking about trying yogurt soju.
