I forgot to mention this, but they revealed this info at Comic-Con.
The blood-orange carbonated drink has a slightly tart and lightly sweet flavor that is sure to taste better than the O negative blood consumed by the show's fictional vampires.
Crafted to replicate the appearance of the synthetic blood beverage preferred by the undead in the series, the real-life drink will also be called Tru Blood.
I'll try it. I'll do it to support the show.
