Definition
Moonshine whisky is illicitly distilled spirituous liquor, produced without governmental authorization, outside the supervision of revenue authorities, and typically without payment of excise taxes. The term encompasses distilled spirits manufactured clandestinely — most often in rural or concealed locations — in violation of federal or state licensing, taxation, and regulatory requirements governing the production of alcoholic beverages.
In the legal contexts where the term appears most frequently, moonshine whisky is functionally synonymous with "privately manufactured distilled liquor" — a phrase used in revenue and prohibition statutes to capture unlicensed spirit production regardless of the liquor's name or method. The defining legal characteristics are (1) that the product is distilled, (2) that it is of sufficient alcoholic strength to be intoxicating, and (3) that it was produced outside lawful regulatory channels.

Common Language
Modern common usage (Wiktionary): Informally produced whisky or other spirits, especially associated with Appalachian or rural American tradition; often used affectionately or nostalgically to describe homemade or craft-style distilled liquor.
Historical common usage (Webster's 1913): Whisky illicitly distilled, usually at night, to evade excise officers; applied to the product of unlicensed stills operated covertly.
The gap between common and legal meaning is modest but worth noting for researchers. In contemporary popular culture, "moonshine" carries a romantic or artisanal connotation and is even used as a marketing term by licensed craft distilleries. In the legal record — particularly across revenue law, prohibition-era statutes, and excise enforcement materials — the term carries no such neutrality. It is a term of legal condemnation, identifying a product whose manufacture constitutes a regulatory and often criminal violation. The nostalgic common meaning should not be imported into historical legal sources.

Why It Matters in Research
This term operates in a narrow but historically significant corridor of American legal materials: federal revenue law, state and federal prohibition enforcement, and the excise prosecution records of the late nineteenth and early twentieth centuries.
Several research traps are worth flagging:
First, terminology shifts across eras. Before national Prohibition (1920–1933), moonshine whisky cases arose primarily under federal internal revenue statutes penalizing unlicensed distilling and tax evasion. After Prohibition's repeal, the term resurfaces in state enforcement contexts and in federal prosecution under the Internal Revenue Code provisions governing distilled spirits. Researchers should not assume that a "moonshine" prosecution in 1890 and one in 1940 arise under the same statutory framework.
Second, the phrase "privately manufactured distilled liquor" — used as a legal synonym in the Bouvier entry — appears in some state prohibition statutes as a defined term of art. Researchers working with Wisconsin materials specifically (the citation 184 Wis. 664 references Wisconsin case law) should check whether that state's prohibition-era statutes use this phrase distinctly from more general liquor offense language.
Third, the sufficient-strength requirement matters. Not all homemade fermented beverages fell within statutes targeting moonshine whisky. Beer, wine, and low-alcohol fermented products were often treated under separate regulatory schemes, or exempted entirely. Legal sources defining moonshine whisky consistently require distillation and intoxicating strength — homemade cider or beer is a different legal animal.
Fourth, enforcement records are scattered. Federal moonshine prosecutions appear in U.S. District Court records and Treasury Department enforcement reports. State prosecutions appear in circuit and county court records with highly variable indexing. Researchers should cross-reference Internal Revenue Service (and predecessor Bureau of Internal Revenue) administrative records alongside judicial sources.

Historical Dictionary Support
Bouvier's Law Dictionary provides the controlling entry: "Moonshine whisky of sufficient strength to be intoxicating is 'privately manufactured distilled liquor.'" The entry cites Thorpe's National and State Prohibition (at page 156) and a Wisconsin case (184 Wis. 664) as authority.
The Bouvier entry is brief but precise, and its precision is its value. It does two things: it anchors the definition to intoxicating strength (a threshold requirement), and it maps the colloquial term onto statutory language ("privately manufactured distilled liquor") that would have appeared in formal charging instruments. This translation function — from popular term to statutory phrase — is exactly the kind of bridge that period legal dictionaries perform well.
What Bouvier does not address is the federal revenue law dimension, which was the dominant legal framework for moonshine prosecutions through most of the nineteenth century. Researchers relying solely on the Bouvier entry will miss the excise and tax-evasion framing that governed most federal cases. The prohibition framing reflected in Thorpe's citation represents one strand of the legal treatment, not the whole.
No other historical legal dictionaries in the current Law Mind corpus contain a dedicated entry for this term.

Jurisdictional Note
Federal and state law addressed moonshine whisky through parallel but distinct frameworks. Federal jurisdiction rested primarily on excise taxation authority; state jurisdiction operated through police power and, during Prohibition, through state-level dry laws. Some states retained independent prohibition or liquor control statutes even after federal Prohibition ended in 1933. Researchers should identify whether a given source is operating under federal revenue law, state prohibition law, or post-repeal state regulatory law before drawing cross-source conclusions.
