Pitt Cola

Pitt Cola is a popular soft drink in Gravity Falls. Stan and Dipper are frequently seen drinking it, and empty cans of it can be seen around the Mystery Shack. One of its slogans is: "It's the Pitts!"

Distribution
Pitt Cola appears to be sold by the can in vending machines, like the one next to the entrance of the Mystery Shack, and also comes in a two-liter bottle. It is called Pitt Cola because in the can there is an actual peach pit. Pitt Cola is also available in a Diet sub type.

Appearance
Pitt Cola packaging is red with a large salmon/pink stripe and the word Pitt on it, in a style that resembles Coca-Cola's logo. Some packaging has what appears to be a smiling peach on it, since Pitt Cola is peach flavored. There have also been scenes with orange and purple Pitt Cola, likely Orange and Grape flavored.

An advertisement for it also appears on the back cover of the magazine Wendy reads in "Tourist Trapped." It is more prominently seen in "The Inconveniencing," before re-appearing as a drink at the Mystery Shack party in "Double Dipper." A bottle of it can also be seen in the theme song, next to Soos, while the main cast is sitting around the campfire listening to Grunkle Stan tell a ghost story.

Trivia

 * Even though Pitt Cola is in almost every episode of the series, the first time its name is said out loud is in The Golf War. Pacifica Northwest was drinking a can of it at the Ye Royal Discount Putt Hutt, where the peach pit went into her mouth while she was drinking it.
 * Pitt Cola is named after Joe Pitt, one of the series directors.
 * Unlike most colas, Pitt Cola has a reddish color.
 * Pitt Cola also comes in "Diet Pitt Cola."
 * Pitt Cola has a peach pit inside of it.  Interestingly, peach pits can be poisonous.
 * In Stan's mindscape there is a cryptogram that reads "SLWW." Once decoded, it reads, "PITT."
