Your typical soda fountain in a fast-food joint features eight boring choices, usually offering nothing more exotic than “Orange.” It’s been that way for decades, but one of the oldest players in the market is finally shattering that paradigm. Coca-Cola is introducing a machine that can pour 100 different flavors. Early prototypes underwent testing earlier this summer and second-gen units are headed for limited markets early next year — the same thing they said about those self-cooling bottles last year. Assuming they do come to market, swapping out the highly-concentrated flavors is likened to changing a print cartridge, meaning new choices can come and go quickly depending on popularity. It all sounds refreshing, but we’re not looking forward to the lines as the thirsty yet indecisive ponder 15 different flavors of Diet Coke.
