In the first half of 2013, SodaStream (NASDAQ:SODA) felt like the king of Fizzy Drink Mountain: the stock doubled during that time. But the second half of 2013 showed an unstable kingdom: when competition appeared, mainly in the form of Coca-Cola buying Keurig Green Mountain (UNKNOWN:GMCR.DL), SodaStream's stock acted like it was about to be overthrown.

In this episode of The Motley Fool's Where the Money Is, consumer-goods editor Mark Reeth has CG analyst Sean O'Reilly discuss whether SodaStream can continue making in-roads in the market, particularly in the U.S., and keep its crown despite competition from Coke the Kingslayer.
