Taste - Decent for a non-carbonated drink. It says that it has 100% juice but, they call it energy juice, so i guess the can is filled with 100% energy juice (hmmm that's interesting, I never knew that guarana, and taurine were made of juice). This taste is a combo of: apple, orange, tangerine, acai, elderberry, and guava juice concentrates. Ahhhh, nice juicy flavor.
RATING - 7.5/10
Buzz - Wow, they really took their energy blend serious. This blend is very similar to that of monsters, except better. Yes, that's right, this drink is better than monster. It has all the same ingredients and their amounts as monster, except Rumba has a lot of vitamins that monster doesn't. Beastin' energy.
