My review of Monster Energy flavors.

I'm going to rank each flavor in terms of flavor, drinkability (higher score = I'll want to drink it more often) and flavor complexity (how rich the flavor is).

Assault:

Best described as slightly fermented coca-cola; It smells very similar to kombucha. It is noticably less tart than cola, with a distinct sweetness in the front, and a nutty taste in the back. The aftertaste is smooth, mildly creamy.

The sweetness is overpowering it, and the lack of sourness is making it feel bland. It somehow tastes more like what I'd imagine cola beans taste like. It's unique, I think the only flavor I've had that somewhat resembles this is Monster Mule. A slice of lemon and some ice would really do it justice. Also, infusing it with nitrous oxide would help, I think.

Bad Apple:

Strong sour apple flavor with a hint of kiwi. Leaves a refreshing tart aftertaste.

Reminds me of the Burn Sour Apple. Simple but well executed, though it can be a bit too intense for some.
