Wyoming liquor laws set clear but sometimes misunderstood age limits for selling and serving alcohol. For example, the minimum age to serve is 21 in most cases, yet an exception allows 18-year-olds to serve in dining areas (but not behind a bar). Selling in liquor stores? You must be 21—no exceptions.

This guide breaks down Wyoming’s minimum seller-server age, legal drinking age, and other essential alcohol handling rules so you can stay compliant, protect your business, and serve responsibly.

Wyoming Alcohol Laws at a Glance

Wyoming’s alcohol service and sale laws are governed at the state level by the Wyoming Liquor Division (WLD), but cities and counties can (and do) impose stricter requirements. Here’s the statewide baseline:
Activity  Minimum Age Exceptions/Notes
Serve Alcohol (Dining Area) 18 Must not mix or pour drinks; only table service allowed
Bartend / Mix / Pour Drinks 21 Applies anywhere, including restaurants
Sell Alcohol (Off-Premise) 21 Applies to liquor stores, grocery stores, gas stations
Legal Drinking Age 21 Exceptions for family supervision at home, religious ceremonies
Sunday Sales Allowed statewide, but local ordinances may limit hours N/A
State Control Not a full control state—private retail sales allowed N/A

Minimum Age to Serve Alcohol in Wyoming

General Rule

The statewide minimum age to serve alcohol is 21—but there’s an important exception that often trips people up.

Dining Area Exception

If you’re 18 to 20 years old, you can serve alcohol in restaurant dining areas only, delivering drinks to patrons at their tables. However:

  • You cannot mix or pour drinks at the bar or service station.

  • You cannot work in bar-only areas or nightclubs.


Why It Matters for Employers:
Hiring 18–20-year-old servers can help fill staffing gaps, but they must be properly trained to understand these boundaries. Allowing them to handle tasks meant for 21+ staff (like pouring wine) can put your business at legal risk.

Minimum Age to Sell Alcohol in Wyoming (Off-Premises)

If your business sells packaged alcohol for off-site consumption (liquor store, grocery store, gas station), the law is strict: you must be 21 to sell alcohol.

Compliance Tips for Sellers:

  • Always verify ID for customers who appear under 30.

  • Only accept state-issued driver’s licenses, military IDs, passports, or tribal IDs as proof of age.

  • Document refusals in an incident log to protect against false accusations.

Penalties: Selling to minors can lead to fines, possible jail time, and suspension or revocation of your alcohol license.

Legal Drinking Age in Wyoming

Standard Rule

The legal drinking age in Wyoming is 21 for all public consumption and possession.

Exceptions

  • Family Supervision: Minors may drink at home if supervised by a parent, legal guardian, or spouse over 21.

  • Religious Ceremonies: Certain faith-based exceptions apply.

  • Limited Employment: 18–20-year-olds may handle alcohol as part of restaurant service in dining areas.

Penalties for Underage Possession or Consumption:

  • Misdemeanor charge

  • Up to $750 fine and/or 6 months in jail

Other Important Wyoming Alcohol Laws

DWUI (Driving While Under the Influence):
The legal Blood Alcohol Concentration (BAC) limit in Wyoming is 0.08% for drivers over 21. Commercial drivers have a stricter limit of 0.04%, and drivers under 21 face penalties for any detectable BAC above 0.02%. DWUI penalties range from hefty fines and mandatory alcohol education to jail time and driver’s license suspension. Repeat offenders face progressively harsher consequences, including ignition interlock device requirements.

Local Ordinances:
While Wyoming law sets the statewide baseline, counties and municipalities can add their own requirements—and many do. For example, certain cities may require all alcohol servers and sellers to complete a local or state-aligned training program, even though Wyoming does not mandate it statewide. Hours of sale, zoning restrictions, and open-container rules can also differ from one community to another.

Sunday Sales:
Wyoming allows alcohol sales on Sundays under state law, but local governments can regulate or restrict these hours. Some towns may ban early-morning Sunday sales, while others align hours with regular weekday operations. Always verify with your local licensing authority to avoid unintentional violations.

Not a Dry or Control State:
Wyoming is not a dry state and not a full control state, meaning private businesses can sell alcohol if licensed. However, wholesale distribution of spirits is managed through the Wyoming Liquor Division (WLD). The WLD acts as the state’s central wholesaler, ensuring compliance in supply and distribution while leaving retail operations to private license holders.

Challenges Encountered by Bar Staff & Businesses in WY

  1. Confusion over Exceptions: Misunderstanding the dining area rule for 18–20-year-olds leads to violations.

  2. No Statewide Mandatory Training: Creates inconsistent knowledge and practices across establishments.

  3. Local Rule Variations: County and city ordinances may differ, catching businesses off guard.

  4. High Liability Risk: Fines and license loss for serving minors are severe.

  5. Increased Enforcement: Tourist-heavy areas see more compliance checks.

Current Trends in Wyoming Alcohol Service

  • More Local Training Mandates: Cities like Cheyenne have stricter training expectations than state law.

  • Technology Use: Digital ID scanners reduce age verification errors.

  • Tourism Impact: Seasonal tourist spikes increase compliance monitoring.

  • Consumer Awareness: Guests are more likely to report improper service to authorities.

Some Practical Tips for Compliance

  • Train all staff on state and local alcohol laws—even if not required.

  • Keep updated copies of local ordinances on hand.

  • Use an ID scanner for consistent age verification.

  • Hold quarterly refresher sessions for staff on acceptable service practices.

  •  Document incidents to protect your business legally.

Learn the Rules and Get Ahead

Wyoming’s alcohol laws may appear straightforward, but the reality is a patchwork of state rules, local ordinances, and exceptions.

Even without a statewide training mandate, completing the Wyoming Alcohol Awareness Training is one of the best ways for bartenders, servers, sellers, and managers to stay compliant and confident.

In Wyoming’s fast-paced hospitality and retail environments, that knowledge is your greatest asset.
