What is the specific gravity of wort?

This results in a dimensionless number, which by brewing convention is usually listed to three decimal places. For example, pure water would have a specific gravity of 1.000, while an unfermented wort might have a specific gravity of 1.048. Finished beer would typically have a specific gravity in the 1.005-1.015 range.

What specific gravity should my beer be?

As a guide, the gravity of a beer should drop about 75 per cent during fermentation, so a wort with a gravity of 1.040 should ferment to a beer of a gravity of about 1.010.

What is wort gravity?

Original Gravity (OG), sometimes called original extract, is a measure of the solids content originally in the wort, before alcoholic fermentation has commenced to produce the beer. OG is one of the major measurements used by brewers to determine the future alcohol content of a beer fermented from a particular wort.

What is OG and FG?

Original gravity (OG) measures how much sugar is present in the wort before it is fermented. The final gravity (FG) is how much sugar is left over when fermentation is done.

What if specific gravity is too high?

Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be. High urine specific gravity can indicate that you have extra substances in your urine, such as: glucose.

What ABV is considered 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 does OG mean on beer?

original gravity
A gravity reading taken just prior to yeast being added, or pitched, is referred to as the original gravity (OG). The OG will provide the brewer with a good idea of the potential alcohol percentage for that particular beer.

How can 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.

Do low gravity beers ferment faster?

The lower the gravity, the greater chance of producing a quality beer in a short amount of time—aim for something below 1.050. British and American session ales generally work well for a fast turn around.

How can you tell the gravity of beer?

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.

Why is the specific gravity of beer unitless?

The reason specific gravity is unitless is that is is simply a measure of the density of the liquid relative to water – so 1.000 would be the density of distilled water, and most wort or beer has a gravity slightly above that of water (1-10% higher actually).

Do you need to boil down wort to hit gravity?

Calculates how much you need to dilute or boil down your wort volume to hit a certain gravity. Helps you hit the correct wort volume and target gravity for your home brewed beer! There are two ways to look at this, which is why there are two calculators below.

What kind of gravity do home brewers use?

Home brewers talk a lot about gravity. It’s not the type of gravity that keeps us on the Earth, but the gravity of their beer recipe. This includes the beer’s specific gravity, original gravity, and final gravity. Brewers measure gravity throughout the brewing process to estimate how many sugars can be converted to alcohol.
