I give the Bang Black Cherry Vanilla a solid B, as it was a refreshing drink with a pleasent taste akin to cherry juice with sparkling water.
The only reason I give it a B over an A, is beacuse it tasted super chemical-ish (which energy drink isn't tasting like a chemical factory?), but it could have been better if the flavour was milder. Although I have to say the drink was super smooth, especially the first few sips where amazing.
I probably wouldn't get this flavour again, as it wasn't anything spectacular. I don't regret purchasing this drink.
