Character mistake: At the ravine, upon learning that the bridge doesn't exist yet, Marty states to Doc "We can't wait a year and a half for this to be built". If you carefully look at the sign, it says the bridge is opening Summer 1886. That's under a year away, not a year and a half from Sept. 1885.

Directed by: Robert Zemeckis
Starring: Christopher Lloyd, Elizabeth Shue, Lea Thompson, Mary Steenburgen, Michael J. Fox, Thomas F. Wilson
Factual error: When Marty goes to meet Mad Dog Tannen for the duel, in the background on the right side is the current flag of California. But that flag did not become the state flag of California until 1911, so would not have been around in 1885.
Trivia: The band playing at the Hill Valley festival is rock band ZZ Top (two guys with long white beards playing guitar, and a drummer), who wrote songs for the film.

Answer: He simply has an absurdly low tolerance for alcohol, and whiskey is not a wise choice if this is the case. It helps set up the joke when Marty asks the bartender, "How many has he had?", and he replies by telling Marty, "Just the one", as we are meant to think Doc has been in the bar all night drinking away his sorrows.
