Another Monster Blog? And it’s Monster Coffee, again? Bear (or in this case, brew) with me. I thought it was worth mentioning Monster’s “Killer Brew”, a beverage so aptly named. A standard monster only has around 160mg of caffeine, but Killer Brew has 300mg instead, nearly double! Killer Brew also comes in two new flavors. This could come in handy in emergencies—like when the coffee at your workplace is bad (or non existent).
