Coca-Cola selling high-end milk in test markets

Falling soda sales have prompted Coca-Cola to dip its toes into a new drink. It's called "Fairlife" and it's a healthier alternative to regular milk.

The beverage is premium milk with 50 percent more protein, 30 percent more calcium, half the sugar of typical milk, and has a higher price tag.

As of right now, Fairlife is only sold in test markets.

The soda giant plans to launch it nationally in 2015.
