From the product website (which you must be 21 to enter), there are apparently 2 varieties - East coast and West coast. All we saw today was the West coast variety, which is ironic, given that I live east of the Mississippi! Both varieties are malt beverages. If you want a good laugh, check out the videos on the website! That's all I say.
After a very short deliberation in which we considered trying some, we agreed we could live without the experience. Neither of us imagined we'd care for it, then we'd be stuck with the six-pack. If you give this a try, I'd love to hear your reaction!
