Upon further investigation on the McDonald's site, the Cherry Berry Chiller consists of ice and "Cherry Berry Flavored Juice Blend" which sounds way too complicated to for it to actually be juice. Divulging deeper into the murky lair it seems as though this mysterious blend does indeed have Apple, Grape, and Raspberry juice concentrate as well as cherry puree. While not fresh out of your local grocer's produce section, this will certainly do for a fast food freeze.
With the beverage in a smooth frozen blend, I sipped deep down and was filled with a vibrant tangy tongue lashing. Lots of different flavors collaborate here and form a much greater rapport than any Big 3 in the NBA. There's no harsh after tones like a lemonade would convey and the flavor is actually something fairly unique and uncharted.
I suspect that this beverage is really the Triple Berry Smoothies younger sister, just lacking the yogurt and all of the unnecessary seeds that drink provides. I'm giving the Cherry Berry Chiller a 3 star rating. Definitely a Summer go-to.
