How Much To Discard When Making Moonshine? - Información de la cerveza

How to Remove Methanol from Moonshine – One way a commercial distiller would determine the presence of methanol is to monitor still temperature, If anything is produced by the still before wash temperature reaches 174 degrees, it’s methanol. A commercial distiller will discard it.

Again, methanol boils at a lower temperature than ethanol and will concentrate at the beginning of distillation runs.
Additionally, commercial distillers have determined that simply discarding a standard amount per batch, based on batch size, is enough to keep things safe.
The rule of thumb is to discard 1/3 of a pint jar for every 5 gallons of wash being distilled.

How much initial product to discard:

1 gallon batch – discard the first 2/3 of a shot glass 5 gallon batch – discard the first 1/3 of a pint jar 10 gallon batch – discard the first 3/4 of a pint jar

Regardless of still temp, it’s a good idea to always follow this rule of thumb. Methanol or not, the first stuff to come off the still tastes and smells like rubbing alcohol. It’s by far the worst stuff in the entire production run and it isn’t going to impress anyone.

How much methanol do you throw out?

Will I make methanol when I distill? You will produce small quantities of methanol when distilling using commercial ‘spirit yeasts’ and sugar/dextrose. The temperature ethanol (drinking alcohol) boils off at is 78C-82C, which is why we are always told to keep our still between these temperatures.

The acetone and methanol boiling temperatures are a lot lower, and this is why they are the first impurities to come out of your still, hence why you should always throw the first 150ml of alcohol (impure alcohols/methanol) that comes out of your still.
As we are only fermenting sugar with a known yeast and nutrient mix (often refered to as ‘Turbo Yeasts’), we know how much by products such as methanol are to be discarded at the beginning, making the process of distillation safe.

If you wish to distill other mixtures (other than brew shop yeast and sugar/dextrose) then the methanol quantity produced is unknown and could prove disastrous! : Will I make methanol when I distill?

How many foreshots do you have to discard?

Glossary: Foreshots Foreshots are the first vapours to boil off during distillation, usually containing compounds such as acetone, methanol, and aldehyde volatiles. Distillers always discard the foreshots and never allow them to be part of the final product.

Depending on the base material used to make the spirit and the apparatus used, foreshots can be 2% to 5% of the overall volume collected.
We always consider foreshots and “heads” as separate parts of the early spirit collection, as for spirits like Gin (or others who are redistilling Neutral Spirit) foreshots are likely to contain the dregs of the previous run left in the tubes.

They may also contain some harmful compounds and are always discarded, while the heads are perfectly potable spirit, but simply an undesirable flavour for their recipe. As the risk of collecting nasty compounds is low when redistilling a pure Neutral Spirit, for gin makers, foreshots are often just 0.1 – 0.2% of the total run, while the heads can be a further 1-3% depending on the recipe.

In this case heads are collected separately, added to tails and sometimes used to make other products. Many distillers who are starting from a wash (i.e. not rectifiers transforming previously distilled Neutral Spirit) such as Scotch Whisky makers and Moonshiners, do not make that distinction and simply separate the distillate as foreshots, hearts and feints.

Is 1 mL of methanol toxic?

Outlook (Prognosis) – Methanol is extremely poisonous. As little as 2 tablespoons (30 milliliters) can be deadly to a child. About 2 to 8 ounces (60 to 240 milliliters) can be deadly for an adult. Blindness is common and often permanent despite medical care.

Theory: Distillation Distillation is a purification technique.

It can be used for the separation of a low boiling solvent from a solid or a high boiling liquid.
The liquid vaporizes in one vessel (the distillation pot) and then condenses into another vessel (the receiving flask).
Heat Sources: Steam Bath – Use with flammable liquids that have a boiling point below 100 oC.

Heating Mantle with Powermite – Use with round bottom flasks during distillation or reflux. The Powermite allows heat regulation. Hot Plate – Use with Erlenmeyer flasks containing non-flammable or high boiling liquids. Can also be used with beakers containing water (for a water bath).

Boiling Point: Boiling point is the temperature at which the vapor pressure of a liquid is equal to that of the surrounding atmosphere. Boiling point varies with atmospheric pressure and is corrected to the temperature that would be observed at sea level (760 Torr). The higher the altitude, the lower the atmospheric pressure and the lower the boiling point.

Boiling point is measured during distillation when the temperature is constant (at the stillhead). Corrected boiling point can be measured using a nomograph or the following equation: Boiling Point Correction Factor = Corrected Boiling Point = Observed Boiling Point + Correction Factor Return to Top Typical Experiment Student A left approximately 20mL of a liquid mixture for his partner, Student B, to work up.

Student B was to remove and identify the solvent as well as retain the residue and distillate.
Student B decided to use simple distillation to remove the solvent.
He placed a lab jack in position and set up a heating mantle with a Powermite control.
He clamped the distillation flask in place and added boiling stones followed by his unknown liquid.

A stillhead was then attached and a thermometer was inserted into the thermometer adapter. The receiving flask was clamped in position and the condenser was connected between the receiving flask and distillation flask. Student B then attached the water tubing to the condenser and turn the water tap on full.

The tubing popped off and sprayed the student’s TA (who was not impressed). The student reconnected the tubing and this time used the hose clamps and turned on the water tap slowly. The student set the Powermite to 25 and after a few minutes, the liquid in the distillation flask began to boil. The solvent began to boil and the temperature of the distillate was observed to be 38 oC at ~700 torr.

When no more solvent distilled over, the heating mantle was slowly lowered and the apparatus allowed to cool before disassembly. Return to Top Practical Lab Tips When connecting the water tubing to your condenser, remember that water enters from the bottom of the condenser and exits from the top.

Add boiling stones to your distillation flask BEFORE you start heating. Distillation is complete when: a) no more liquid collects in the receiving vessel, b) when the temperature of the thermometer starts to drop or c) when the distillation flask is empty. Return to Top Q: When using the water condenser, which hose connector is water-in and which is water-out? Water goes in from the BOTTOM of the condenser.

Return to Top Q: Why does it matter whether the water enters the condenser at the top or from the bottom? If water enters from the bottom of the condenser, it will always be completely filled with cold water which ensures efficient cooling. During distillation, vapors are formed in the heated distillation flask.

The condenser cools these vapors condensing them back to liquid droplets that flow down the condenser into the receiver flask. A completely filled condenser provides maximum cooling therefore allowing for maximum recovery of the purified liquid during distillation. Return to Top Q: How fast should the water run through the condenser? A continuous flow of water through the condenser is necessary; however, the lower the flow rate, the lower the pressure and the lower the chance of having the tubing pop off (resulting in you spraying yourself or others).

Return to Top Q: How far down the stillhead should the thermometer bulb be placed when setting up the distillation apparatus? The mercury bulb of the thermometer should be positioned so that vapors condense readily on it. The tip of the bulb should be in line with the lowest part of the connecting tube of the stillhead.

Return to Top Q: How do you know when distillation is complete? Distillation is complete when: a) you notice a drop in temperature, b) no more distillate is being formed or c) the distillation pot is empty. Return to Top Q: Why are no drops coming over eventhough the distillate is boiling? There could be two reasons for this: If this happens at the beginning of the distillation, there is insufficient energy input to cause adequate vaporization of the liquid.

In this case, you should increase the heat. If this happens at the end of the distillation, almost all of the low boiling liquid has been removed. Solvent vapors trapped in the boiling stone pores will continue to be an ebullition source, causing bubbling.

Return to Top Q: Can I use a bunsen burner for reflux and distillation? It is safer to use a heating mantle with a Powermite control for flammable vapors.
The Powermite also makes it easier to control the temperature.
Return to Top Q: When setting up the distillation apparatus, can I use an Erlenmeyer flask for the receiving flask? Yes, but there are less organic vapors if you use a small round bottom flask.

Return to Top Q: How much does boiling point vary with atmospheric pressure? For most organic liquids, there is a decrease of 0.5 oC with every 10 torr difference from 760 torr Return to Top Q: If the atmospheric pressure is 695 torr today, does that mean the actual boiling point of this liquid is listed in the literature at a higher value than the temperature I saw, even after I corrected the temperature for my thermometer? Yes.

Why would you distill vodka 5 times?

Is more distilled vodka better? – Some people believe that more distilled vodka is better. However, there is no real evidence to support this claim. In fact, most vodkas are distilled two or three times, so there is no real difference between the brands.

The distillation process for vodka can be done multiple times in order to create a high-quality product, Some argue that the more times vodka is distilled, the better the end product will be. However, over-distilling can also affect the flavor and aroma of vodka, so it is important to do this process correctly,

When vodka is distilled, the end product is a clear, odourless liquid. However, if it is distilled too many times, the vodka can become harsh and flavourless. This is because over-distilling can remove some of the natural flavours and aromas that make vodka enjoyable to drink,

What happens when you distill alcohol multiple times?

An Example of Triple Distillation – Each distillery’s process to double and triple distillation is vastly different, but for the basis of this article I will succinctly explain a standard approach. The fermented distillers beer, at about 8 to 12% ABV, is first distilled in the stripping still – commonly referred too in the Whisky World as the Wash Still.

The distillate, now called the low wines, is about 25% abv and is held in the Low Wines Holding Tank.
It is then mixed with the tails from the preceding low wines distillation and distilled in the Intermediate Still.
This Intermediate Distillation is then split into two parts: strong and weak (those tails).

The latter will be mixed with the next lot of low wines and redistilled in the Intermediate Still. The strong portion is taken forward to be redistilled in the spirit still. This runs as normal, with the heart of the run (referred too as new make spirit) being separated from the Heads and Tails, which are mixed with the distillate obtained from the Intermediate Still, and then redistilled in the Spirit Still.
