Pruno, also known as prison wine, is an alcoholic beverage that is made by inmates in prisons using a variety of ingredients. The ingredients used to make pruno include apples, oranges, fruit cocktail, fruit juices, hard candy, sugar, high fructose syrup, and possibly other ingredients, including crumbled bread. Contrary to popular belief, bread does not contain yeast for the pruno to ferment. The concoction can be made using only a plastic bag, hot running water, and a towel or sock to conceal the pulp during fermentation. The end result has been described as a "bile flavored wine-cooler". Inmates are not permitted to have alcoholic beverages, and correctional officers confiscate pruno whenever and wherever they find it. In an effort to eradicate pruno, some wardens have gone as far as banning all fresh fruit, fruit juices, and fruit-based food products from prison cafeterias. However, even this is not always enough, as there are pruno varieties made almost entirely from sauerkraut and orange juice. Food hoarding in the inmate cells in both prisons and jails allows the inmates to acquire ingredients and produce pruno. During jail and prison inmate cell searches, correctional officers remove excessive or unauthorized food items to halt the production of pruno.
