I realize it's probably not the healthiest thing, since it has 22g of sugar, contains corn syrup and artificial flavoring... but it was a one time try and I'm a sucker for interesting flavored products. The flavor is very similar to drinking actual Root Beer soda in milk, minus the carbonation. It's good, but not something I will probably drink again. lol.
