- "Joey! Let's make some wake-up juice."
- — Chester to his assistant Joey
Wake-up juice was a type of drink created by Chester and Joey at the Palace Saloon in 1885 as an antidote to alcohol, which Emmett Brown was forced to drink after passing out from drinking whiskey. According to the novelization, it contained green pepper juice, tabasco sauce, cayenne pepper, chili peppers, onions, and mustard seeds. However, in the movie, only five ingredients are mixed together and no chili peppers are added to the drink. It caused Doc to immediately wake up, run outside, and dunk his head in the horse trough (which Chester had earlier told "Clint Eastwood" was the only place to get a drink of water at the saloon).
