Good to know
Once a small rig starts to feel cramped, a 4 gallon onion-head copper pot still is the natural next step. It's hand-formed from heavy copper, so you get room for bigger batches with the same honest build: every joint sealed with lead-free tin-silver solder, and no brass anywhere. The craftsmanship shows in every curve.
Why step up to a 4 gallon copper pot still?
More capacity per run means more distillate to study. A larger charge makes the run last longer, which gives you more time to watch the temperature climb and see how the flow changes from start to finish.
- Complete set: copper boiler, time-honored onion-head dome, swan neck and a condenser with a thermometer port.
- Copper does chemistry: as vapor rises through the dome and swan neck it meets copper, which reacts with sulfur compounds and helps produce a cleaner distillate.
- Making cuts: on permitted spirit runs, collect in small jars. Then you can separate heads, hearts and tails by smell and proof instead of guessing.
- Beyond spirits: the same rig handles essential oils and distilled water. Neither one involves producing alcohol.
Owning this still is legal across the US. If whiskey, rum, brandy or moonshine is on your list, get your federal TTB permits first. Every run after that is an experiment you design: pick the charge, set the heat, read the numbers, refine. Have a question about this size? We're happy to help.
