Oogave Root Beer

This is the second tasting for Oogave, an organic and caffeine free soda line using agave nectar as its sweetener. I'm picking up notes of cinnamon in the smell from the bottle. The actual flavor I get from this however, I feel is lacking. It's kind of like tasting that vegan alternative of one of your favorite foods... the basic gist is there, but somethings just off. It's actually a little bitter to me, but the one thing it has going for it is a lot of carbonation. I just think the flavor needs some work.
