Being an energy drink, i would evaluate the kick it has, maybe offering it to someone with a different caffeine consumption than mine and seeing how they react.

Also doing another evaluation as the step before.

First things first, nice design.

For the flavour part i want to highligh, depending on what type of beverage (caffeinated or not? for athletes? for gamers? etc) it is.

Secondly the composition of the flavour (Is it carbonated or still? Is it sweet or sour? Is it more bitter? What are the first flavors that come to mind when I taste it? Have I tasted this flavor somewhere else or does it offer a unique experience?)

These would be my main concerns. Then an evaluation on the brand (is it new? never heard of it? could this beverage be confused for another one? does this can smells/tastes like the aluminum or its fresh?)

Thanks for the opportunity to work with you.
