# Quick Answer: What Is A Gravity Point?

## How do you find original gravity?

Before you can get an OG, you must get an SG (specific gravity) reading by using a hydrometer or similar instrument.

The SG compares the density of the beer (or wort) to the density of water.

Water has a specific gravity of 1.000.

When grains for the wort are added, the density increases..

## How do you adjust the original gravity?

There are several possible means of adjusting the values, depending on whether the actual volume and gravity are above or below the targets. Diluting the wort with water will increase the volume and decrease the gravity, both before and after the boil. Adding fermentables will increase the gravity.

## How do I lower my final gravity?

Adding some dry beer enzyme or beano will break down the complex sugars in the dark malt, and some of other nonfermentables, but you may end up with a thin beer afterwards. A more controllable approach is to blend the beer with a low gravity, higher alcohol beer, but this of course requires another batch of beer.

## How much does sugar increase gravity?

Simple sugars are another great option to boost ABV. One pound of sugar adds approximately 1.009 specific gravity points per 5 gallons.

## What does high original gravity mean?

“High-gravity” refers to brewing a beer with high original gravity (OG)—typically, above 1.075 OG is considered high. OG is a measure of the fermentable and un-fermentable substances in the wort before fermentation.

## How many gravity points does sugar add?

Corn sugar yields 42 gravity points per pound per gallon (ppg) and is 100 percent fermentable.

## What if my original gravity is too high?

If the gravity is too high, dilute it by adding boiled or sterile water: This time we’ll assume our target was 1.056 but we overshot and came in with a gravity of 1.064, again using a 5 gallon batch. We’ll use the fact that the number of points times volume should be a constant to do the dilution.

## What is final gravity?

The Final Gravity is the specific gravity measured at the completion of fermentation and represents the amount of unfermentable sugars remaining in the beer. … For example if you have a yeast with a 75% attenuation rate and your original gravity is 1.050 the estimated final gravity would be about 1.012.

## When should I start reading gravity?

Gravity readings are typically taken before pitching the yeast and after visible signs of fermentation have ceased. It is generally not recommended to take more samples than necessary because each time the fermenter is opened to draw out wort, you are introducing the risk for contamination.

## What should my original gravity be?

Most 5 percent ABV beers have an original gravity around 1.050. Bigger beers like American Barleywines and Imperial Stouts can surpass 1.100 with smaller beers like an American Light Lager or Berliner Weisse rarely exceed 1.030. The color of a beer can provide clues to its density.

## What if my original gravity is too low?

Correcting Your Original Gravity If your gravity is too low, the calculation for the amount of dry extract to add is: Calculate the difference between your target and actual OG, then multiply by 1000. For example if you were targeting 1.056, but only hit 1.048 this would give us (1.056-1.048) x 1000 = 8 points.

## What is a gravity reading?

A gravity reading refers to the total amount of dissolved solids in water, since we’re talking about beer, those dissolved solids are sugars. … A gravity reading taken just prior to yeast being added, or pitched, is referred to as the original gravity (OG).

## How do you read Gravity?

It really comes down to a simple 4-step process:Retrieve Sample & Insert Hydrometer. You will need to take your first measurement after the cool down, prior to pitching the yeast. … Obtain the Original Gravity Reading. … Calculate with Temperature. … Repeat to Obtain Final Gravity Reading. … Careful, Don’t Overdo It.

## What is a specific gravity point?

Specific gravity is the ratio of the density of a sample to the density of water. The ratio depends on the temperature and pressure of both the sample and water.

## How are gravity points calculated?

To calculate the number of gravity points, take the specific gravity, multiply by 1000 and subtract 1000. Pale malt usually has a specific gravity of 1.036. So, pale malt has 1036-1000 = 36 gravity points.
