Hop-Up Soda

Hop Up Cola is a brand of soda that appears in Rapture. Interestingly, the soda could be found in only one place in the first Bioshock, in a trash can in Hephaestus where the game erroneously labels it "coffee". It appears to have more visibility in Bioshock 2, including a bottle cap seen on the back of the Big Sister's Big Daddy doll and an advertisement poster.
