In Operation Pacific, a 1951 John Wayne movie, when Wayne's submarine crew get arrested for crashing and busting up a luau with the local Hawaiians asking for damages beyond Wayne's budget, he finds out the locals had illegal "okoolihau" which caused his men to get drunk.

While the US Bureau of Alcohol, Tobacco, Firearms and Explosives once recognized okolehao as a unique class, like vodka, gin, bourbon, tequila, whiskey, liqueur, etc., it is now recognized as a distilled specialty spirit (DSS), which requires the producer or distiller to include the exact ingredients and general formula on the label.
