Jet Brew is a chain of coffee used in the show. It is a parody of Starbucks, the name (and possibly the logo) is a parody of the airline service, Jet Blue. Mostly bought by Jade West, this is a beverage that has been in two Nickelodeon Shows. (It was also featured in iCarly). Tori and Trina have both been seen drinking Jet Brew that Jade found in the garbage. Andre was seen drinking this coffee in
The Birthweek Song when he was offered it, and Trina wanted Jet Brew in that same episode. André describes the coffee as "so good."
The logo is an image of a blue airplane, printed on the side of their typically styrofoam cups. Jade is a known customer who frequently purchases the coffee, along with Beck.
Trina also appears to like Jet Brew because in The Birthweek Song she asked to finish Tori's coffee (which Jade found in the garbage) and asked for coffee again when Andre was offered some Jet Brew.
Jade goes to 'Jet Brew' the most.
