Biofuel Caffeinated Popcorn ($3-8) is not the solution to the world’s energy problems, and it isn’t brewed from organic detritus. It is, however, a creative way to stave off afternoon narcolepsy. Taste-wise, Biofuel teeters between salty and sweet, a la Kettle corn, while packing a 150 to 200mg wallop of caffeine per bag (roughly two energy drinks worth of jitter juice). That makes each of the bag’s 4.5 suggested servings basically equivalent to a cup of coffee. Wolfing down the entire bag, on the other hand, is closer to downing a fistful of methamphetamine or 1/4th of a can of Four Loko.
