On the left is the 'Red Bull Energy Drink Winterdition Citrus Mandarin Flavor,' and the can has an orange-based design reminiscent of mandarins. On the right is the regular version of Red Bull.

However, because Celsius energy drinks contain around 200 milligrams ... The Fantasy Vibe sparkling mandarin marshmallow tasted like an orange creamsicle. I had low expectations for the Fantasy ...

It's got a slight orange tint but mostly it's the neon-ish yellow/green you'd expect from an energy drink. The orange is Fanta-style artificial but crisp. There's a lot of bold flavor here.

I tried every Celsius energy-drink flavor I could find and ranked them from worst to best. One clearly blew the others away.
