# How do you calculate alcohol content from specific gravity?

## How do you calculate alcohol content from specific gravity?

Your percent alcohol can be given by the formula: ABV(%) = (Initial Gravity – Final Gravity) * 131.25. So if your initial gravity was 1.108, and your final gravity was 1.041, your beer is approximately 8.79% alcohol by volume. Once again, this is only an approximation, and loses accuracy as the alcohol content goes up.

**How do you work out the percentage of alcohol?**

For example, wine that says “12% ABV” or “alcohol volume 12%” means 12% of the volume of that drink is pure alcohol. 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.

### What does specific gravity mean in alcohol?

Specific Gravity, sometimes called present gravity, is the density of beer or wort at standard temperature and pressure (20°C, 760 mm Hg) measured by saccharometer, hydrometer, or refractometer. A more accurate laboratory method is by weight using a specific gravity bottle.

**How do you measure alcohol content after distillation?**

The proofing hydrometer, also called an alcoholmeter, is used to measure the final alcohol content of your distilled moonshine. It can usually take measurements up to 200 proof (100% ABV). To take a measurement, you simply float the hydrometer in your moonshine and look at the ABV/proof reading on the side.

## What percentage is high gravity?

A high gravity wort is typically considered in the range of 14°–17°Plato and will result in a beer of 6%–8% ABV. A very high gravity wort has a solids content greater than 17°Plato and will usually have an alcohol content greater than 8%. High gravity brewing is performed by brewers for two reasons.

**What is a high percentage of alcohol?**

Generally, the ABV is between 4 percent and 8 percent, with 5-6 percent being the standard for most beers in the United States. Some craft beers nowadays are as high as 12 percent.

### Does high gravity mean high alcohol?

Given the right conditions, environment and care, certain yeast strains in high-gravity wort are capable of producing very large amounts of alcohol, which is why the “high-gravity” descriptor is synonymous with a high alcohol percentage.

**How much alcohol is in high gravity beer?**

A high gravity wort is typically considered in the range of 14°–17°Plato and will result in a beer of 6%–8% ABV. A very high gravity wort has a solids content greater than 17°Plato and will usually have an alcohol content greater than 8%.

## What does specific gravity equal?

The term specific gravity, symbolized sp gr, refers to the ratio of the density of a solid or liquid to the density of water at 4 degrees Celsius. The term can also refer to the ratio of the density of a gas to the density of dry air at standard temperature and pressure, although this specification is less often used.
