Industry City Distillery -- Vodka for chem geeks?
I just stumbled on this interesting organization, and I thought I'd share. <strong><a href="http://drinkicd.com/"
target="_blank">Industry City Distillery</a></strong> uses a cool process to ferment their beet sugar into ethanol. They utilize a
specific strain of yeast that they've immobilized in alginate beads. They put these beads into glass reactor columns and feed their reactant solution
through. Pretty damn cool, and <em>very</em> environmentally friendly. I'm not sure if it's their original idea, or if they got it from
someone else, but somebody should earn a green chemistry prize for this.
I'm hoping to order a bottle or two of No.3 when I get one of my tax returns. (Yeah, that's right. Poor unemployed guy living in urban area wasting
his low-income tax return on booze! Maybe the government-funded healthcare I'm getting will pay for replacement kidneys? Suck a bag of dicks,
Republicans!)
Anyways, I thought this was just too damn cool not to share... so check it out! This is basically porn for people like us:

cool stuff and drink in good health .why is it steel is said to produce poison alcohol if used as a still yet i see stainless steel used all the time.
i have a pressure cooker that is stainless steel and have tons of copper tubing now and summer will soon be here so i want to make ethanol again.

Sounds like hype, I can imagine what is actually being achieved here; maybe if they were precisely controlling pH and temperature but the alginate
beads sound bogus. What's not environmentally friendly about normal fermentation?

It's a continuous fermentation process
rather than batch process.

Regular Steel? Too much iron becomes dissolved in the brew. Some African tribes, that practice fermentation in iron vessels, have suffered thereby.
Stainless Steel resists corrosion, and thus stays out of the brew. Copper, at least on the consumer level, is much cheaper than Stainless. More
available too. Got Copper tubing at the local hardware store. Stainless tubing is hard to come by.

However I fail to see how this topic justifies unwarranted insults against Republicans with the comment "Suck a bag of dicks, Republicans!". If you
can dish it out when it was so clearly uncalled for in this topic, then you can take it without whining. Especially since no two physical objects can
occupy the same place at the same time and democrats were and are already there doing just that.
Instead of being brainwashed by liberal professors with rabid hatred your education investment would be better served learning the little things like
how to spell 'beads', it is not 'beeds'. Only a brainwashed individual would spew hateful insults against such a large group with their own outlook on
life without the slightest justification or provocation beforehand.

I thought the "bag of dicks" jab was pretty funny, though perhaps a bit hypocritical in light of the fact that we were just lecured by him in the joke
thread in whimsy for being crude, lol.
That is very interesting. I may have to get a bottle too, with my low income tax return, hehe.

No hissing merely making my own equal and opposite 'joke'. I notice jokes always go one way on this site. Someone has to be the opposing point of
view. I could have reacted the leftist way and asked the ACLU to sue because my 'belief system group' was unfairly targeted. Instead I took the
'diamond' approach and countered with the equal and opposite view.

Is there a new handbook for tea-baggies out? Something like "The sensible fascist?" 
(pls sensibly notice the symbol placed at the end o the line before. Regards)
Immobilisation on alginate is the oldest of these techniques and comparably easy although it escapes me why they are doing it (except that its good
promotion). It has no advantages at all for ethanol production. A normal fermentation is basically selfcontrolled, such a continous process calls for
a lot of sophisticated sensoric and control.
Let me guess....
They have a nice show running producing a littel alcohol this way, makes a good press and marketing.
The real mass of alcohol they are buying on the overflowing free market as everybody with a brain would do, run it through some Britta waterfilter
style equipment and voila'! here we go.

I wondered if anyone would point that out.
<strong>IrC</strong>, I have two things to say to you:<ol><li>I made a typo. I know how to spell "beads", thank
you.</li><li>Get over yourself. It was a joke. Let's not start another pointless political flame-war. If there had been an opportunity
to take a jab at another large group of morons, I would have taken that. I'm an equal opportunity cynic.</li></ol>[note]
I had typed out a longer, more thoughtful and eloquent response, but it was lost.

Did you read these links? The first one is about targeted deliver of viral agents, the second is about a gelatin free alternative for general
pharmaceutical consumption.
Neither of these relate to fermentation or explain why fermenting with yeast in alginate is better than tossing it into the mash directly. As for the
continuous fermentation. Why? Judging by the picture there is very little volume in those fermentation vessels I can't imagine continuous fermentation
is so superior it's worth it to sacrifice so much money and convenience.

Yes I read them. I was responding to your comment "the alginate beads sound bogus" by showing the common use in industry of similar encapsulation of
similar materials. By similar I mean living organisms. The first link is from the largest company involved in your 'bogus' alginate beads which
ironically produces "alginate beads". I was showing encapsulation of organic life is common. When you called the beads 'bogus' it sounded like you
were disputing the existence of said technology. I did not bother going into the subject of why they are being used to make brew. Or whether or not it
is a desirable approach. However it did momentarily cross my mind reading once the termination of the fermenting organisms at high alcohol content is
a limiting factor. My thought was I wonder if this approach protects the organisms longer allowing a stronger brew. Just idle thought on my part,
thinking of the top of my head if you will. Do not see why you would rag me for posting of the links since at least one and the pdf I uploaded are
from a manufacturer of alginate beads. Likely the maker of the very ones being used in the brew which started the topic.
It just seemed to be logical to assume the beads protect the fermenting organism allowing the continuous production.

This is close
to what I think they're doing. It's not so much about the death of the yeast, but that they change their metabolism at high alcohol content, which
corresponds also to lower sugar content. I'm not a brewer personally, but what I've read seems completely sensible, that when yeast are well-fed in
ideal conditions the dominant metabolic product is ethanol. Stress them with low food and high alcohol and the metabolic pathway shifts, and they
start producing fusel alcohols, which are mostly 3-5 carbon single alcohols. But they also produce various diols and longer-chain alcohols; these are
more viscous and give rise to the alternate name fusel oils. For a vodka, these are all off-tastes, and the goal seems to eliminate them as much as
possible before distillation.

I am sure you are correct in all this but laws limit maximum proof and they do not need alginite beads for that, so this is why I said "momentarily
cross my mind " about why the beads. Isn't it possible their reason is more related to the continuous production protection for the yeast and to a
lesser extent about the percentage of alcohol. Anyway, this was why I stressed 'momentarily'. They have been making fairly high proof brews for eons
without the need for this new esoteric method. Just thinking out loud.
Yet another question:

Since this is about science geeks is there a reason the entire assembly, condenser and all, cannot be 100 percent geeky glassware most of us already
have?
By the way if you have industries such as chicken processing plants within your area, they are a goldmine of stainless steel tubing in many sizes and
of the highest quality. Tyson's has an incredibly huge junkyard of it and no doubt so do many other similar companies. If you get to know whoever runs
their maintenance department you might be able to make fantastic deals on it.

IrC probably because stills can hold gallons and are cheaper to run. i just didnt understand why the fermented brew can be warmed in stainless steel
pots and condensed with copper tubing. apparently stainless steel is not like carbon steel or tin and is accepted but i wanted to be sure. i made it
with a tin can and it smells delicious and it being poisonous probably kept me sober. my ethanol burns clean and i still have 1 pint but just knowing
that it is toxic makes me feel that i didnt achieve making real alcohol. ah hell maybe i'm just kidding myself.

"it being poisonous probably kept me sober"
Explains some of the craziness in Chicago during prohibition. They made it in strange devices and drank it too. I knew an old lady nearing the end of
her days in the 70's who told some amazing stories of the roaring 20's. She had the first wringer washer in her part of town but it never washed
clothes it's first decade of existence. It was used as a still supplying a few speakeasy's . I never really quizzed her about the method of
manufacture. Don't remember if she ever said in detail, other than mentioning the washer was the mash container and was run for agitation (probably
only every so often during a run). No idea what the condenser was or where it was hidden in raids but the washer stood in plain view always completely
overlooked during raids. The wringer (was that the name?) was two rollers on top, hand cranked to squish dry clothes. One time they were searching
around she described running a shirt through it the whole time to distract them from looking inside. Seems it was full of the next batch. Wish I would
have thought to ask her if there was any odor coming from it (I've never made brew) because it seems there should have been. I think. If you worry
about your tin can brew I have to wonder what was in something made in a washing machine, and what effect it had on those drinking it. She knew Capone
and Nitty, on occasions they drank some of her alcohol. Sure would explain a lot about their behavior in those days.

I imagine that baking bread would easily mask the odor. There's an old washing machine, as you describe, in the basement of my brother's house. He
already does home brewing. I wonder if we could try it out—<em>for science!</em>
