Yes, home brewing beer is legal in Montana under federal and state law. Montana aligns with the federal Craft Beverage Modernization Act, permitting adults 21+ to brew up to 100 gallons (50 gallons per adult in a household) annually for personal, non-commercial use. The Montana Department of Revenue (DOR) and the Alcoholic Beverage Control Division (ABCD) do not regulate home brewing as long as it complies with federal excise tax exemptions and avoids sales or distribution. Local ordinances typically defer to state and federal guidelines, though some municipalities may impose zoning restrictions on storage or equipment.
Key Regulations for Home Brewing Beer in Montana
- Volume Limits: Home brewers may produce up to 100 gallons per household annually (50 gallons per adult if multiple brewers reside together). Exceeding this triggers federal excise tax obligations under 26 U.S.C. § 5053.
- Age and Intent Restrictions: Only individuals aged 21 or older may brew, and production must be for personal consumption—sale or barter is prohibited. Violations may result in misdemeanor charges under Montana Code Annotated (MCA) 16-4-106.
- Equipment and Storage: Local fire codes and zoning ordinances may govern storage of flammable materials (e.g., propane for brewing) or large-scale equipment. The Montana Fire Prevention Code (adopted via MCA 7-33-2201) requires compliance with NFPA standards for home brewery setups.
Note: While Montana does not impose state-specific permits for home brewing, the 2026 Federal Excise Tax Adjustment (part of the Consolidated Appropriations Act) may alter tax thresholds for small producers. Brewers should monitor updates from the TTB and Montana DOR for compliance shifts.
