In the movie 'Twilight' what is Charlie's choice of drink? (Not Rainier beer.)

Well seeing as Rainier beer is his drink of choice all I can think you want is what he refers to it as which is 'Vitamin R'

"I’m actually talking about Charlie’s and Billy’s drink of choice: Rainier Beer.

Charlie, the protagonist’s dad, referred to Rainier Beer as “Vitamin R.” There were at least three scenes that showed Charlie getting back from the store with two, 6-packs of Rainier “tall boys,” or slugging down a can of Rainier Beer while listening to Bella talk. There’s even one scene where Bella says something like, “Here dad, have another one of your favorites,” referring to the beer."
