Its actually a form of distilled battery acid that is drained from Military Tanks in the middle east.
Don't worry about the toxic properties, as they are weakened by the boiling in potato-eye syrup (proprietary mixture).
After the fermentation and aging process (in discarded 55 Gallon oil drums, steeped for over 2 weeks on each "end" of the drum) the concoction is squeezed through painter's drop-cloths and pressurized into the vending containers.
Its a pretty refreshing drink, once your taste-buds become numb.
Be sure to take a big GULP all-at-once, to savor the full "Beverly Effect".
