ABV Calculator: The Most Reliable Homebrew Calculator

The total quantity of alcohol in the beer is calculated by measuring your original gravity before the process of fermentation and then your final gravity after the fermentation is accomplished. In the case you add other fermentables such as fruits and additional sugars after taking your original gravity reading that has to be accounted for on their own, you can just use two numbers to determine the amount of alcohol by its volume. The reason behind the fact is that alcohol is less dense than water. This concludes that wort ferments and the sugars which were converted into alcohol, the density of the beer will decrease.

 ABV Calculator is a handy one-stop tool used for calculating the ultimate ABV percentage of your fermented beverages. In order to calculate the ABV, you just need to measure the original gravity (OG) of your wort or must on the day you made it. In the case, you did not get the measurement, the anticipated gravity based on the sugar content and volume. And then measure the final gravity (FG) on the day you package the beverage.

The fundamental formula used by most of the homebrewers is pretty simple.

ABV = (OG - FG) * 131.25

ABV stands for Alcohol by Volume.

OG stands for Original Gravity.

FG stands for Final Gravity.

So, by using this formula with a beer with an OG of around 1.055 and an FG of around 1.015, your ABV should be 5.25%.

And the warning is that this formula only gives in an approximate ABV Calculator. In reality, the formula becomes less accurate way to figure out the alcohol content. But it usually requires quite a bit of math to do. Therefore, unless you already have a accurate alcohol by the weight measurement.
