Question: What does proof mean when referring to alcoholic beverages? Answer: Proof is defined as twice the alcohol (ethanol) content by volume. For example, a whisky with 50% alcohol is 100-proof whiskey. Anything 120-proof would contain 60% alcohol, and 80-proof means 40% of the liquid is alcohol.

#### Is 100% alcohol equal to 50 proof alcohol?

Conclusion – The strength of liquor is measured in proof, which is twice the percentage of alcohol by volume. For example, 80-proof vodka contains 40% alcohol.100-proof whiskey contains 50% alcohol.150-proof rum contains 75% alcohol. The difference between 100 and 151-proof liquors is that the higher-proof liquors are more concentrated and therefore have a much higher level of ethanol (alcohol).

## Is 80 proof alcohol 40% alcohol?

It is twice the percentage of alcohol by volume. For example, an 80 proof vodka would contain 40% alcohol by volume. Often, you will see beer and wine labels displaying ABV and liquor labels displaying proof.

#### Is 200 proof alcohol 100% alcohol?

200 Proof Alcohol: Contains 100% Ethanol. (Specification is 200 Proof) All Ethanol products have a proof associated with the product description. The proof is the measure of water content of the Ethanol portion of the product and any level of proof can be manufactured based upon the amount of water added.

- Pure Undenatured Ethanol: Pure Ethanol is Ethyl Alcohol with no other additives or denaturants.
- Pure Ethanol is often referred to as pure alcohol even though the term “pure” can refer to any proof.
- Pure Alcohol is considered “pure” regardless of the “cut” of water (proof).
- Pure Alcohol (Ethanol) is commonly referred to as Beverage Grade Alcohol.

It is always 192 proof and derived from natural sources. Pure USP Alcohol: Pure Alcohol is also often referred to as USP Alcohol. That is because only pure, undenatured Ethanol can be certified as USP or NF Grade. Not all pure alcohol is USP grade certified, but only 190 and 200 proof pure ethanol which meets or exceeds the stringent standards set forth in the US Pharmacopoeia.

Natural vs. Synthetic Ethyl Alcohol: All Ethanol products can be made with naturally derived Ethanol (Grain alcohol or grain neutral spirits) or synthetically produced Ethanol. Natural alcohol is commonly referred to as Grain Alcohol. While grain and synthetic alcohol are technically the same, there are differences in the limited amount of contaminants in the product in the parts per million (ppm) range.

Federal Excise Taxes & Permits Required: All Pure Ethanol products may be purchased without a permit from the Alcohol and Tobacco Tax Trade Bureau (TTB). All pure alcohols (ethanol) are considered ‘Taxable Alcohol’. TTB requires payment of excise tax of $13.50/proof gallon (200 Proof, Pure Alcohol = $27.00/Wine Gallon).

- A tax exempt certificate is required to be on file with Capitol Scientific to avoid paying federal excise tax on pure alcohol.
- Federal & State Law Requirements: You must be the age of 21 or over to purchase of pure ethanol (non-denatured) alcohol products.
- All TTB, federal, state and local laws must be complied with.

You may be required to furnish a state or federal license even if purchasing products with federal excise tax added. Please contact us directly for help with determining your licensing requirements.

#### How many shots of 99 proof to get drunk?

Alcohol and Weight – The influence of alcohol on the nervous system depends on the quantity you have in your bloodstream. Because alcohol is being distributed across the body by plasma (the water content in the blood), it dilutes a bit faster if you have enough water in your bloodstream.

## What alcohol is 110 proof?

(US) Used other than figuratively or idiomatically: 55% alcohol by volume.

## What is 100 percent alcohol called?

Pure ethanol is called absolute alcohol.

### Why is vodka so strong?

Vodka is a strong alcohol made by fermenting grains or vegetables like potatoes. The core ingredient used in the fermentation process affects the overall flavor and experience of the vodka.

### Why proof instead of percent?

Why Alcohol Content Is Measured in ‘Proof’ Did you ever wonder why alcohol content is measured in “proof” — and why that number differs from the other number you’ll see on your bottle of vodka and whiskey, ABV (alcohol by volume)? While alcohol by volume, or the percentage of alcohol in the liquid, is a standard measure of alcohol strength across the world (a 30 percent ABV spirit in the U.S.

also a 30 percent ABV spirit in France), the proof scale varies. And if that sounds a little fuzzy — kind of like how you might feel if you’ve had a few – here are a few facts about proof to help provide clarity: 1: Proof is so called because, back in England in the 1500s, the government would on liquor containing a higher amount alcohol.

Alcohol content was determined via a rather crude test. Basically, the government would soak a gun pellet with alcohol and try to set fire to the gunpowder. If it lit, the alcohol content in the liquor was high enough gunpowder to ignite, the liquor was to be deemed to be a “proof spirit” — as in, there was proof it contained a high amount of alcohol — and was taxed at a higher rate.2: Because this method of providing proof of alcohol content wasn’t very precise or reliable, England in 1816.

- The new system involved scientifically precise measures of density and gravity and set the “proof” threshold at 57.06 percent alcohol by volume.
- This measure was standardized 1952.
- In the U.K., a 100 proof spirit is about 57 percent ABV and the ratio of proof to ABV is 4 to 7.
- You get the proof.
- Around 1980, however, the U.K.

began to adopt a straight ABV scale for labeling spirits. (Phew.) 3: In the United States, the system — — is a bit simpler: “Proof” is straight up, So a vodka, say, that is 40 percent ABV is 80 proof and one that is 45 percent ABV is 90 proof. A “proof spirit” is 100 proof (50 percent ABV) or higher.4: In France, they use a scale measured in, instead of proof.

### What percent alcohol is 50 proof?

Whether wine, beer, spirit, cider or hard seltzer, every alcoholic beverage label is required to show how much alcohol it contains, What can be confusing is the multitude of ways it can be written. The two main methods for indicating the alcoholic content of a beverage are alcohol-by-volume (abv) and proof.

- In the United States, a spirit’s proof is simply double the abv.
- This means the liquid in a bottle of 90-proof bourbon is 45% abv, while a bottle of 151-proof rum is 75.5% abv.
- So, where does proof come from and why do we still use it? Most sources point to 16th century England, where higher taxes were levied on spirits above a certain strength.

Without the tools to measure the exact alcohol level of a spirit easily and accurately, its strength was tested by a much simpler method: Will it catch fire? If the liquid was strong enough to burn (or ignite a gunpowder pellet soaked in it), it was considered proof that the bottle was strong enough to warrant the extra tax.

Privacy Policy This, of course, is a generally poor way to measure the amount of alcohol in a spirit.

- Combustibility depends on factors beyond abv, as anyone who’s ever lit a 90-proof whiskey on fire can attest.
- The temperature of the liquid plays an important part, too.
- Warmer liquid and ambient room temperate allow for more alcohol vapor to escape, increasing flammability.
- Absent a more scientific process, the “proof” of a liquid could change on warm day versus a cold one.

It does, however, explain why drinks like wine and beer were historically never referred to by their proof. They would never ignite and not be subject to the extra tax, so there was nothing to prove. By the 19th century, more accurate techniques had been discovered to measure the amount of alcohol in a spirit, namely figuring out the liquid’s specific gravity, or density.

- As alcohol increases, spirits generally get lighter—this is how it’s possible to float different spirits on top of each other in cocktails.
- In England, this led to a “proof” spirit being officially defined as a one that was 12/13th the gravity of an equal volume of distilled water when measured at 11°C (51°F).

In other words, this amounted to about 57% abv being defined as a “100 proof” spirit in the United Kingdom. If you find this math confusing, you’re not alone. Around 1848, the United States, seeking a simpler system, defined a spirit’s proof as simply double the alcohol percentage.

- Thus, stateside, 100 proof became synonymous with 50% abv, which is coincidentally around the same alcohol level that allows a spirit to easily ignite.
- Meanwhile, a French chemist named Joseph-Louis Gay-Lussac found the arbitrary assigning of numbers by politicians setting tax standards to be inefficient, and in 1824 created his own system.

For the French scale, measured in degrees, 100% alcohol was simply 100 proof, while plain water was 0 proof. In France, the proof was the abv. Such it became that a bottle of liquor with 50% alcohol-by-volume could, at the same time, be designated as 100 proof in the U.S., 50 proof in France, and 87.6 proof in Britain.

Everclear Grain – 95% ABV Popularly known as the grain alcohol or a neutral spirit, Everclear is distilled from 100 selected grains.

- The final result is 95% ABV (190-proof) liquor.
- Everclear Grain has a neutral flavour profile and is colourless and odourless.
- The alcohol is used in the international market for creating various cocktails and blends.5.
- Golden Grain – 95% ABV Coming from the makers of Everclear Grain, Golden Grain is manufactured by American company Luxco.

Another strong alcohol, Golden Grain is a 100% neutral spirit distilled from grain. Similar to Everclear, it’s colourless and odourless. It is majorly used for creating homemade liqueurs and extracts.6. Spirytus Rektyfikowany- 95-96% ABV From the land of Poland comes Spirytus Rektyfikowany with 95-95% ABV.

This rectified spirit is made using premium ethyl alcohol with an agricultural cereal origin. Spirytus is often used as a base for liqueurs and other infusions and drinking it directly isn’t recommended at all. Describing the liquor one sampler told the New York Post “It’s like getting punched in the solar plexus” and an endorsement read, “Pilots in Siberia used to drink it.” 7.

Cocoroco – 96% Made from sugarcane, Cocoroco is extremely high in alcohol content by volume – 96%. This Bolivian booze is potable alcohol sold in a tin. Cocoroco is illegal in some countries due to its high ABV. Disclaimer: Kindly read the label before consuming any of these liquors.
