Homebrewing is legal for adults across the U.S. at federal level, but it comes with limits and responsibilities, and it involves real hazards: boiling liquids, open flames or high-power electric elements, chemical cleaners and pressurised gas. This guide summarises the federal rules, points to where state and local law matters, and sets out the safety practices for each hazard. It draws on the Alcohol and Tobacco Tax and Trade Bureau (TTB), the American Homebrewers Association (AHA), NFPA fire-safety guidance, the Brewers Association and product documentation. It is general information, not legal advice; check the rules where you live.
Federal rules on home production of beer
The TTB’s beer FAQs set out the federal position:
- An adult may produce beer for personal or family use without paying tax, up to 100 gallons per calendar year if one adult lives in the household, or 200 gallons per year if two or more adults live there.
- Adults are defined as 18 or older, or the age required to buy beer in the locality.
- Adults may not produce beer for sale or offer it for sale.
- Beer may be removed from the home for personal or family use, including organised affairs, exhibitions or competitions such as homebrew contests or tastings.
- TTB regulations do not authorise production contrary to state or local law.
The AHA maintains a summary of state homebrewing statutes, which is a useful starting point for local rules on transport, competitions and events. See safety and regulations.
Fire and burner safety
Many brewers move to propane burners once batches grow beyond what a kitchen stove can boil. NFPA’s grilling safety advice applies to propane burners as well:
- Use propane equipment outdoors only, well away from the house, garages, overhangs and anything flammable.
- Check hoses and connections for leaks with a soap-and-water solution: bubbles mean a leak.
- Store propane cylinders properly and keep children at a safe distance.
Additional brewing-specific practices:
- Use a burner stand designed to carry the weight of a full kettle, on level, non-flammable ground.
- Never leave a lit burner unattended, and keep a suitable fire extinguisher nearby.
- Electric brewing systems draw high current: follow the manufacturer’s electrical requirements and have a licensed electrician install dedicated circuits with ground-fault protection where needed.
Hot liquids and lifting
Boiling wort causes serious burns, and a full kettle is heavy. Plan your process so you never carry boiling liquid across a room: use a valve, a pump rated for hot liquid or a siphon, and cool wort in place where possible. Wear closed shoes and heat-resistant gloves, keep children and pets out of the brewing area, and watch for boilovers as the boil starts and after hop additions.
Chemicals
- Read every cleaner and sanitiser label before use; many carry hazard warnings (one acid sanitiser’s EPA registration required the signal word “Danger”).
- Wear eye protection and gloves when handling concentrates.
- Never mix chemicals; bleach with acids or ammonia releases dangerous gases.
- Store chemicals in original labelled containers, out of reach of children.
Routines are in cleaning and sanitising.
Pressure
- Bottle only when gravity is stable to avoid over-carbonation.
- Use a regulator between any CO2 cylinder and a keg; manufacturer manuals warn that connecting a cylinder directly can cause an explosion.
- Secure cylinders upright; the Brewers Association advises chaining or otherwise securing them so they cannot tip.
- If CO2 leaks, ventilate and leave the area.

Setting up a safe brew space
| Area | Checklist |
|---|---|
| Hot side | Outdoors for propane; stable stand; clear of flammables; extinguisher |
| Cold side (fermentation) | Temperature-controlled space; electrical equipment kept dry |
| Cleaning | Sink or tub; chemicals stored safely; eye protection |
| Packaging | Secure CO2 storage; ventilated space for kegerators |
| Household | Children and pets kept away during brewing |
See homebrew setup and beginner equipment.
Drinking responsibly
Homebrew strength varies with the recipe and fermentation; estimate alcohol content from your gravity readings. Serve homebrew only to adults of legal drinking age, and never drink and drive.
Pre-brew safety checklist
- Burner set up outdoors on level, non-flammable ground, away from buildings; hoses and connections leak-tested.
- Extinguisher within reach; children and pets kept away.
- Kettle sized with enough headspace; plan for moving hot wort without carrying it.
- Heat-resistant gloves, closed shoes and eye protection ready.
- Cleaner and sanitiser mixed per label, in labelled containers.
- CO2 cylinders secured upright if kegging; regulator in place.
- Enough time: rushing is how burns and boilovers happen.
Frequently asked questions
Can I sell my homebrew?
No. The TTB states that adults may not produce beer for sale or offer it for sale under the home production rules. Selling beer requires the appropriate federal and state permits.
Can I bring homebrew to a competition or club meeting?
Federal rules allow removal for personal or family use including organised affairs, exhibitions and competitions. State and local laws also apply, so check the AHA’s statute summary and your local rules.
Comparisons of equipment are in equipment comparisons, and all guides are under Brewing Guides. Start with the equipment guide if you are new.
Is brewing indoors on a gas stove safe?
Kitchen stoves are designed for indoor use and many brewers start there with small batches. Ventilate well, never leave the pot unattended and avoid oversized pots that overhang burners. Propane burners designed for outdoor use must stay outdoors.
Does the 100-gallon limit apply to wine and cider too?
The TTB has separate rules for beer and for wine made at home. The figures in this guide come from the TTB’s beer FAQs; check TTB guidance on wine for cider and mead questions, and state law in both cases.
