The Keurig Kold, which has been in development for six years, will go head-to-head with similar devices from SodaStream, a rival home carbonation company that's developed a close partnership with PepsiCo. Both devices face headwinds in the form of shifting consumer preferences as shoppers increasingly abandon sugary drinks in favor of healthier alternatives. That trend has caused SodaStream's stock to plummet; it's unclear if Keurig Kold will fare any better.
