So I just picked up a bottle of this at 7-11. I had not heard of this before and I am a big fan of regular Bawls so I thought I'd try it, even though it was $2.29 for one bottle. After tasting this new version of Bawls I can say it is now my favorite.
As far as root beer goes, it definitely tastes quite a bit like Barq's (not surprising since Barq's is also a caffeinated root beer.) I think it had a nice root beer flavor with just the right amount of bite to it. If you are a fan of either Bawls or root beer I would definitely recommend picking up some of this new product. According the the website you can purchase Bawls at CompUSA, MicroCenter and Target (as well as a few online retailers) however I've yet to find it at my local Target store.
