## What is the specific gravity of alcohol?

For example the starting specific gravity for an average ale or lager will be in the range 1.038-1.050 and for a wine, around **1.075-1.095**. This reading is termed the original gravity, or OG.

## How do you calculate alcohol content in homebrew?

The volume of the alcohol in the solution can be calculated as follows. **Specific Gravity at the start of fermentation, minus the specific gravity at the end of fermentation, divided by 7.36**.

## How do you calculate alcohol percentage?

People making their own alcoholic beverages often calculate the percentage of alcohol by volume by **measuring their relative density with a hydrometer** or their sugar content with a refractometer. These simple instruments cleverly detect how much sugar gets converted into alcohol during the fermentation process.

## How do you calculate alcohol by volume?

You can work out how many units there are in **any drink by multiplying the total volume of a drink (in ml) by its ABV (measured as a percentage) and dividing the result by 1,000**. So, to work out the number of units in a pint (568ml) of strong lager (ABV 5.2%): 5.2 (%) x 568 (ml) ÷ 1,000 = 2.95 units.

## What is proof vs ABV?

(Phew.) 3: In the United States, the system — established around 1848 — is a bit simpler: **“Proof” is straight up two times alcohol by volume**. 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.

## How accurate is ABV?

For wine at <=14% the tolerance is ± 1.5%, but may not exceed 14% eg a wine of real abv 13.0%, may be labelled in the range 11.5-14%. For wine >14.01% the tolerance is ± 1%, eg a wine of 14.4% may be labelled 13.4-15.4%. Values are always rounded to the nearest 0.1.

## Can you calculate ABV without OG?

Yes, there is, but only **if you have both a refractometer and a hydrometer handy**. You need both the final gravity from the hydrometer, and the brix value from the refractometer. If you have both of these values, you can determine the ABV without knowing the original gravity using a calculator.

## What is the strongest alcohol?

**Here are 14 of the strongest liquors in the world.**

- Spirytus Vodka. Proof: 192 (96% alcohol by volume) …
- Everclear 190. Proof: 190 (95% alcohol by volume) …
- Golden Grain 190. …
- Bruichladdich X4 Quadrupled Whiskey. …
- Hapsburg Absinthe X.C. …
- Pincer Shanghai Strength. …
- Balkan 176 Vodka. …

## What vodka is 60 proof?

Stateside, a liquor’s proof is two times the ABV. So this means that a **beverage with 30% ABV** is 60 proof.
