Stump liquor is a slang term for moonshine, or homemade alcoholic beverages made from grains such as corn or barley. Synonyms for stump liquor include white lightning, hooch, mountain dew, firewater, and corn whiskey. These terms all refer to the clandestine production and distribution of unregulated alcohol, often associated with rural areas and prohibition-era America. While moonshine was once a relatively common illicit activity, it is now considered dangerous and illegal in most places. Despite its reputation, however, stump liquor is still enjoyed by some as a traditional spirit with a distinctive flavor and cultural significance.
