At the recent NACS show in Las Vegas, Red Bull announced that they are bringing 3 special edition flavors over to North America.
They've previously been released in select European markets, but now we'll get a chance to try The Red Edition (Cranberry), The Blue Edition (Blueberry), and The Silver Edition (Lime). These are the first flavor extensions for Red Bull.
Taking a look at Red Bull's Austrian website, we can pull (and translate) some details from the Editions FAQ. It's noted that these flavors are based on the same traditional Red Bull formula, with the different tastes added on top. Additionally, Red Bull notes that these products have a different look from their other products because "variations in taste need their own design."
Watch for these to arrive in March 2013.
