Step 3: Distillation

What is Distillation?
Distillation in science describes a process in which the boiling points of substances in a solution are utilized to separate the compounds.

How does this apply to our mash?
Well, to make it a higher percent alcohol, you need to separate it from the water and other by products of fermentation.

How do you do that?
Well, you need a distillation apparatus of course.

How do I make one?
Depends what type do you want to make?

What types are there?
Well, there are three types

Pot still
Fractionating Still
Compound Still

With that in mind, you may ask "which is the easiest to make" and the answer would be the pot still. However, the pot still is not very efficient and you would have to distill over and over again to reach a purity of 90%. On the other hand, if you were to use a fractionating still, you would have to only distill 2 or 3 times to reach such a purity. Finally, if you were to use a compound still, you would only have to distill once to obtain the same purity,
I will not really go over how to make any of these stills step by step but by explaining the process, you should be able to make your own.

Pot Still.
A pot still is a vessel that holds the mash and once it boils, collects the vapor and re-condenses it to a liquid form.

Fractionating Still
This still is much like a pot still; however, this still has material on the top that makes the vapor condense and fall back into the pot. Some of it however collects on the condensers and eventually will be able to reach the top of the column and be collected as it hits a condenser.

Compound Still
Much like a fractionating still but runs the vapor in a closed loop. After an equilibrium is achieved, you can slowly extract the alcohol that has reached the top.

Still Basics
if you are making a condenser, use copper it has very little heat resistance.
Also, use copper for apparently it makes it taste better.
For fractionating and compound stills, more surface area the better. Pot scrubbers are commonly used.
Never use an open flame, for alcohol vapors are explosive.
There is alot of math involved in creating the right size etc. with the fractionating and compound still.
To reduce the amount you need to distill as well as to increase the amount of alcohol present, use a pot still to do a strip run. A strip run is when you use a pot still to reduce the amount of water by collecting 100% of the vapors until 100 degrees C.
Patience is the key, and greed will get you an inferior product.
At 1 ATM or 760 mmHg, the max percent obtainable from distillation is 96% without a chemical to break the attraction between water and alcohol. Most chemicals that do that, are poisonous such as benzene .

Under the carboy paragraph you've carboy misspelled as carbon
I kept thinking that I'd read it's legal to brew for personal use, not for sale. Basically, you can't go into business.
Last time I checked, it was still legal in the US to distill up to 100 gallons per year for PERSONAL consumption which includes use as a biofuel (although you will need a very low sugar content in the solution for biofuel). You may NOT sell it NOR transport it without a license.
Hi ,<br>Can any one help me out in some calculation work its really very urgent , please help me out ..... i need to consume 1932.3kg/hr of CO2 with the help of Algae in a pond (water) for example Raceway pond , so i need to know the specific area to construct that pond and its sizing and dimension (length,etc) and the quantity of water needed and amount of algae used so that it easily consumes the mentioned amount of CO2 rate per hour..... please help me out soon you can also drop your suggestion and questions if any my email id is : sudhirmalik2011@gmail.com ....i will be waiting for your reply soon and i'll be highly thankful to you, if someone can help please do tell me its very urgent....<br><br>Thank you
use sherry yeast , it yields highest % of alcohol, if it is added to a normal sugar water base.
The problem here is one of definition. Ethanol = ethyl alcohol and methanol = methyl alcohol. Alcohol is a chemical term for a group of substances of which methanol and ethanol are both a part. Because ethanol is the alcohol that isn't poisonous to humans, it's what most people think of when they hear the world &quot;alcohol&quot;.<br />
64.7 &deg;C is the boiling point of methanol and is poisonous in rather small amounts such as 3 ml. at 10 ml causes blindness.<br/><br/>ethanol has a boiling point of 78.4 &deg;C<br/><br/>When distilling fruit mass it is recommended to boil it slowly to 80&deg;C and keep it at that<br/>If temperature was higher the distillate wouldn't contain as much flavour.<br/>If distilling that way you should throw away the head (its about 1% of distillate)<br/>(fruit distillates yeld about 15 % of mass) , keep the middle and save the tail.<br/>Then you mix tail with water (50-50)and distill it again if you want it drinkable.<br/><br/>cybercorfu plx be more comprehensive in your posts ; <br/>&quot;ethanol=alcohol methanol=toxic&quot; &lt;--not equal<br/><br/>
I'm impressed! you sound like you know what yer doin. maybe you can answer a couple of questions for me. first, whats an " auto-siphon" and where can i git one? second, can you add more sugar and yeast and re-rack it again?
Ok, well here is the thing. An auto-siphon basically allows you to siphon without creating a suction with your mouth. I would highly recommend it and can be purchased from really any home brew store. As for the add more sugar and yeast re-racking, well there it can depend. I am not real sure what you are asking, but if you mean a solution that you already fermented sugars in, aka already has an alcohol content then its a yes but only to a certain degree. Basically, certain yeast are only capable of fermenting to a certain percent then they die from alcohol as it messes with the stability of the yeast. the typical yeast does around 8-13 percent. if you get champagne yeast, it can prob do up to 18% and some mixtures (with yeast, yeast hulls, and other nutrients) can prob do up to 21 or 22%. However, i wouldn't recommend really anything above 18 cause it really isn't all that good tasting. You get alot of fusal and other weird tastes. As for figuring out how much sugar to add to how much water, I would suggest you by a hydrometer, which is a floating weight with a scale on it that measures specific gravity. the specific gravity of water is 1 and as you add more sugar, it goes beyond 1 and when it is fermented all the way, the meter should be lighter than 1. I think it was .999. There is a certain ratio of sugar to alcohol conversion and most of these hydrometers have a thing on it as well that will tell you. Hope that answered your questions.
fer anybody what cares, alcohols vaporize at specific temperatures. here they is, Acetone-134 F, Methanol-147 F, Ethyl Acetate-171 F, ETHANOL-172 F, 2-Propanol-180 F, 1-Propanol-207 F, Water-212 F, Amyl Alcohol-280 F, Furfurol-322 F. hope this helps somebody!
Not Methanol my friend but rather ethanol big diference... Boiling point <br/>78.4 &deg;C, 352 K, 173 &deg;F of ethanol=alcohol methanol=toxic<br/><a rel="nofollow" href="http://en.wikipedia.org/wiki/Methanol">http://en.wikipedia.org/wiki/Methanol</a><br/>
Got a little confused on the spelling.<br/><br/>Mash!=Mass<br/>Carboy!=Carbon<br/>Healthy!=Healthily <br/>
No, Mash is not a misspelling, you apparently don't know beverage fermentation terminology. A mash is the combination of fermentable liquids and the yeast. Same again with Carboy, a carboy is a large glass container, one of those 5 gallon jugs that hold water for water dispensers. They are commonly used in hobby fermentation, both wine and beer making.
I know, he spelt mash as mass carboy as carbon, etc
O really? Meh it must have been the auto spell checker.
Is there anything else readers of this Instructable would like? I wrote this a while ago and there is always more to be added. However, I am only interesting in investing time if there are specific things people are looking for. Merci.
This is more of a science lesson than an instructable. It would be more useful to see pictures/description of your (not you're) own still. How can I make one from material readily available from a hardware store?
You can make it from hardware store supplies. But as i said, i have not made one for it really is illegal for the purpose of what this instructable. I am considering obtaining a fuel permit to make E85. If I do, i will post pictures of what i made. But honestly, I am also kind of reluctant to post the ones I have designed for it took weeks to develop them. Many of them are a bit unusual but theoretically very effective. Additionally, there are many factors that will determine the viability of a still. material you use, length of parts, width, surface area etc. There are like atleast 15 different formulas that must be used. The information here, is really like everything you need to know except the making of a still. The images that are attached to this, is really all u need. replace the lab glassware parts for parts that serve the same purpose.
You mean like kettles and copper pipe? I agree.
Aww, what a pity such a low score despite all the work. Very well, I will include a plan to make your own still from common hardware store goods. Look for it in the following days.
one of the bold things at the top wasn't bold like the others and in the 2nd to last paragraph it says "are dificult to make and require years" years of what?
