>They may be describing a radical new chemistry that I'm not familiar with.

It's probably pot still vs. reflux still. Chemists use fractionating columns to get better separation. Home distillers won't necessarily do so, so official advice has to assume they will not.

Yeah column stills exist for home use but they’re not very popular. They’re big and expensive and strip flavor. It’s probably because Home distilling, like home brewing, is largely focused on the craft side rather than trying to get drunk cheaply.

If you’re trying to get drunk cheaply, and without tasting liquor, you cannot beat the product and efficiency of a column still.

But I want my whiskey or apple brandy to have the characteristics of the mash I distill it from. A column still would reduce that.

So most home distilling is a pot still for sure.

We could be breaking new grounds with spinning band distilled moonshine.
