Also, You Can't Make Vodka in a Pot Still

I apparently struck a nerve with yesterday's Tito's post. In barely 24 hours it has received 135,000 pageviews. That is so much more than what my posts usually get, I am blown away. Now I know how Katy Perry feels.

The post has received many comments, both here and on Facebook, and I've received quite a few emails about it, including from industry folks. Several have pointed out the difficulty of distilling vodka in a pot still, especially a true alembic without the benefit of a rectification column. If you talk about 'old-fashioned pot stills,' as Tito's does, then you're talking about alembics like the ones pictured above.

The problem is that to strip 95 percent of the water from a fermented mash that is 8 to 10 percent alcohol, you need multiple passes through a pot still. That simply means you run it, then take the condensed distillate and run it through again. It takes eight to ten passes through a pot still to achieve the 95 percent alcohol concentration necessary for a spirit to be called vodka. That's just chemistry, there is no way around it.

If you would like a distiller to explain it in greater detail, click here.

Now on to economics. If you did run a spirit through a pot still ten times and achieved the 95 percent alcohol concentration, you couldn't charge $20 a bottle for it. There is too much time and labor involved. Don't say, "well maybe Tito has figured out a way." No, he hasn't, it can't be done and it is not being done, by Tito or anyone else.

Tito's isn't alone in this. Far from it. Many of the products marketed as 'legal moonshine' are the same deal. Some 'legal moonshine' is corn whiskey, some is 'sugar shine,' some is a mixture of the two. Many, including most of the flavored products, are our old friend grain neutral spirit (GNS), i.e., vodka. Since 'legal moonshine' isn't a recognized type of distilled spirit, the small print must tell you what it really is, although some use the catch-all 'distilled spirit specialty' classification, which doesn't really tell you anything. In many cases, though, the words 'grain neutral spirit' or 'neutral grain spirit' are right there on the label. You just have to look for it.
