The Prohibition Amendments are the 18th Amendment, which banned the production, sale, and transport of alcohol nationwide starting in 1920, and the 21st Amendment, which repealed that ban in 1933 and handed states broad power to regulate alcohol inside their own borders. That second amendment is the one that still matters day to day. It is why liquor laws look nothing alike from one state to the next, why some counties are still dry, and why shipping a bottle of wine across a state line is a legal question with dozens of different answers.
What the 18th Amendment Did
Congress proposed the 18th Amendment on December 18, 1917.1Congress.gov. Amdt18.4 Proposal and Ratification of the Eighteenth Amendment It banned the manufacture, sale, and transportation of intoxicating liquors within the United States, along with importing and exporting them.2Constitution Annotated. U.S. Constitution – Eighteenth Amendment Nebraska pushed ratification over the three-fourths threshold on January 16, 1919. A built-in one-year delay let businesses wind down, and Prohibition took effect on January 17, 1920.3Congress.gov. Amdt18.1 Overview of Eighteenth Amendment, Prohibition of Liquor The amendment gave Congress and the states shared authority to enforce it.
The amendment itself was short. The rules came from the National Prohibition Act, better known as the Volstead Act, which Congress passed on October 28, 1919. The Volstead Act set the definition of “intoxicating liquor” at any beverage with 0.5% or more alcohol by volume. That threshold pulled in beer and light wine alongside spirits, leaving almost nothing legal to drink.4Congress.gov. Constitution Annotated – Section: Amdt18.5 National Prohibition Act
There were narrow exceptions. Doctors could prescribe alcohol as medicine. Religious organizations could obtain permits to buy sacramental wine. Industrial alcohol for fuel, dye, and antiseptics stayed legal under a strict permit system.4Congress.gov. Constitution Annotated – Section: Amdt18.5 National Prohibition Act Each exception also became a channel for diverting legal alcohol into the illegal market.
Why Prohibition Collapsed
The law was comprehensive on paper and unworkable in practice. The Bureau of Prohibition employed roughly a thousand investigators to police the drinking habits of an entire country.5FBI. The Bureau and the Great Experiment Bootleggers, speakeasies, and organized crime filled the gap. Public support eroded as violence climbed and, once the Great Depression arrived, the loss of alcohol tax revenue became harder to justify. By the early 1930s the political will to keep the experiment going was gone.
What the 21st Amendment Did
The 21st Amendment’s first section is blunt. It repeals the 18th Amendment outright.6Congress.gov. U.S. Constitution – Twenty-First Amendment What makes it unique in American constitutional history is how it got ratified. Congress required approval by specially elected state conventions rather than state legislatures. No other amendment has ever been ratified that way. Delegates were elected for the single purpose of voting on repeal, which sidestepped the usual legislative dynamics.
Ratification moved quickly. On December 5, 1933, Utah became the thirty-sixth of the then forty-eight states to ratify, clearing the three-fourths threshold and ending Prohibition.7History, Art and Archives, U.S. House of Representatives. The Ratification of the Twenty-First Amendment The federal enforcement machinery built under the Volstead Act was dismantled.
How the 21st Amendment Still Shapes State Alcohol Law
Repeal was only half the story. Section 2 of the 21st Amendment says the transportation or importation of liquor into any state in violation of that state’s laws is prohibited.6Congress.gov. U.S. Constitution – Twenty-First Amendment That single sentence handed states a level of constitutional authority over alcohol that they do not hold over most other products, and it is the reason liquor law is still largely a state-by-state affair.
States have used that power in very different ways. Seventeen states and several local jurisdictions operate as “control” states, where the government itself runs wholesale distribution and, in some cases, retail liquor stores. The rest use license systems where private businesses handle sales. More than eighty counties across nine states are still completely dry, banning alcohol sales outright, and local governments in those areas set their own penalties for unauthorized sales.
Almost every state also uses some version of a three-tier system that separates producers, distributors, and retailers. A brewery sells to a licensed distributor, and the distributor sells to a bar or store. The same company generally cannot operate at more than one tier. The structure exists to prevent the vertically integrated setups common before Prohibition, when large producers owned saloons and used them to push out competitors. It also creates a trackable supply chain that makes tax collection and product recalls easier.
State excise taxes stack on top of federal ones, and rates vary widely by beverage and by state. Moving alcohol across state lines for resale usually requires specific permits and payment of the destination state’s taxes. Annual retail liquor license fees alone run from under a thousand dollars to more than forty thousand, depending on the jurisdiction.
Where State Power Stops
State authority under the 21st Amendment is broad, but the Supreme Court has drawn a line: states cannot use it to discriminate against out-of-state businesses in ways that violate the Commerce Clause.
In Granholm v. Heald (2005), the Court struck down laws in Michigan and New York that let in-state wineries ship directly to consumers while blocking out-of-state wineries from doing the same. The 21st Amendment, the Court held, does not authorize states to favor local producers over out-of-state competitors.8Justia U.S. Supreme Court. Granholm v. Heald, 544 U.S. 460 (2005) The Court reinforced the point in Tennessee Wine and Spirits Retailers Association v. Thomas (2019), striking down a Tennessee law that required liquor store license applicants to have lived in the state for at least two years. Protectionism, the Court said, is not a legitimate interest under the 21st Amendment.9Supreme Court of the United States. Tennessee Wine and Spirits Retailers Assn. v. Thomas States can still address genuine public health and safety concerns, but economic protectionism dressed up as alcohol regulation will not survive review.
What the Federal Government Still Controls
Repeal did not end federal involvement. The Alcohol and Tobacco Tax and Trade Bureau (TTB) is the primary federal regulator of alcohol production today. Any business that wants to operate a distillery, brewery, or winery must apply to the TTB and receive approval before producing anything. There is no federal fee to apply for or maintain a TTB permit, but the paperwork and compliance load is substantial, particularly for distilled spirits.10Alcohol and Tobacco Tax and Trade Bureau. Applying for a Permit and/or Registration
Federal excise taxes apply to all commercial alcohol. Distilled spirits are taxed at a general rate of $13.50 per proof gallon, with a reduced rate of $2.70 on a small producer’s first 100,000 proof gallons. Beer is taxed at $18.00 per barrel generally, and as little as $3.50 per barrel on the first 60,000 barrels for small domestic brewers. Wine rates depend on alcohol content, starting at $1.07 per wine gallon for still wines at 16% alcohol or below.11Alcohol and Tobacco Tax and Trade Bureau. Tax Rates
Federal law also draws a sharp line between homebrewing and home distilling. Brewing beer or making wine at home has been legal since 1978. Home distilling remains a federal felony. Under 26 U.S.C. § 5601, producing distilled spirits without a permit can bring up to $10,000 in fines and five years in prison, and the law specifically prohibits operating a still in a dwelling or on any premises connected to a residence.12Office of the Law Revision Counsel. 26 USC 5601 – Criminal Penalties
Shipping is another federal restriction worth knowing. Sending alcohol through the U.S. Postal Service is illegal. Title 18 U.S.C. § 1716 classifies all alcoholic beverages as nonmailable.13Office of the Law Revision Counsel. 18 USC 1716 – Injurious Articles as Nonmailable Private carriers like UPS and FedEx do ship alcohol, but only between licensed parties and only under the destination state’s rules on direct-to-consumer shipments. Those rules vary a lot: some states let consumers receive wine from out-of-state wineries with an annual permit, others prohibit direct shipments of spirits entirely, and permit fees for out-of-state shippers can run from nothing to more than a thousand dollars a year.
