Wilkins here once more, copper still in one hand and a cup of coffee in the other. My namesake, the old Pittsfield doctor, was a man of many trades — dentist, barber, gunsmith, saloon-keeper, and proprietor of an eating house with a caged bear out front. He understood that the right tool makes all the difference, whether you're pulling a tooth or pulling a clean cut of spirit. Today let's talk about choosing the right kind of still: pot or reflux.
This single distinction confuses more newcomers than any other, so let me untangle it for you plainly.
A pot still is the ancient, beautiful, simple design: a boiler, a head, and a condenser. Heat your wash, the vapor rises, turns through the head, and runs down through the condenser into your collection vessel. That's it. The genius is in the simplicity.
Because the vapor takes a short, direct path with little chance to re-condense and re-distill, a pot still carries all the congeners — the flavor compounds, oils, and esters — along with the alcohol into your glass. This is exactly what you want for character-rich spirits:
A pot still typically delivers spirit somewhere in the range of 40% to 70% alcohol per run, depending on your wash and how skillfully you make your cuts. It will not give you a flavorless, ultra-high-proof product — and that is the entire point. Our 6 Gallon Onion-Head Copper Pot Still is a textbook example of the breed. If you love flavor, the pot still is your soulmate.
A reflux still adds a tall column above the boiler, often packed with copper mesh or fitted with plates. As vapor climbs that column, some of it cools, condenses, and falls back down — this falling-back is called reflux. That liquid is re-boiled and re-distilled again and again on its way up, in effect performing many distillations in a single run.
The result is a much higher-proof, much cleaner, more neutral spirit — 90%+ alcohol is achievable. A reflux still strips away most of the congeners along with the impurities. That makes it ideal for:
The trade is right there in the chemistry: the same reflux that scrubs away impurities also scrubs away flavor. You buy purity with the currency of character.
Hold the two ideas side by side:
Neither is "better." They are different instruments for different songs. Asking which is superior is like asking whether a fiddle is better than a flute — it depends entirely on the music you intend to make.
You'll notice some of our most beloved stills carry a thumper and worm — see the StillZ 6 Gallon Copper Still with Thumper and Worm. A thumper is a sweet middle path: a second small chamber the vapor bubbles through, giving you a modest second distillation — a bit more proof and refinement — while still keeping the glorious flavor of a pot still. The "worm" is the classic coiled copper condenser submerged in cool water, the way the old-timers ran their spirit down the mountain. It's traditional, effective, and easy on the eyes.
If your heart is set on whiskey, rum, brandy, or honest full-flavored moonshine — and for most folks finding their way into this craft, it is — buy a copper pot still. Start your run with flavor; you can always chase purity later. If your dream is crystal-clear vodka or a clean gin base, a reflux design is your tool. Browse the whole fleet on the shop page and choose the instrument that plays your song.
Yours in vapor and seam,

Pot-still man at heart, though I'll not hear a word spoken against an honest reflux column.
