Pitt Cola

Pitt Cola is a popular soft drink in Gravity Falls. Grunkle 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. Pitt Cola also is available in a Diet subtype.

Appearance
Pitt Cola packaging is pinkish-orange with 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". You can also see a bottle of it in the theme song, next to Soos, while the main cast is sitting around the campfire listening to Grunkle Stan.
