Ever heard of pruno? It’s an illicit drink made secretly by prisoners in the California prison system. Over at The Black Table, Eric Gillin created a step-by-step, illustrated guide on how to ferment your own batch. And oh, does he make it sound good!

By most accounts, pruno isn’t something a normal human would want to drink, so potent that two gallons is said to be “a virtual liquor store,” enough to get a dozen people mindblowingly wasted. And while it tastes so putrid that even hardened prisoners gulp it down while holding their noses, they’ll go to incredible lengths to make it, whipping up batches from frosting, yams, raisins and damn near everything.

It’s Miller Time.
