Father's Day is a special occasion and it is a great excuse to make your father a special drink.
This list includes some of the most popular "manly drinks," most of which require one type of whiskey or another but a few also feature rum,tequila,or a little of everything (see Long Island Iced Tea). The point is that he probably doesn't want any of the fruity, creamy or otherwise "girly" cocktails and you won't find any of them here.
Pick up your dad's favorite spirits and mix him up one of these very "masculine" drinks.
