![]() That’s why our cutting-edge bar inventory software, BinWise, can do the heavy lifting for you. Brewers have been using this same formula for centuries, so 131.25 has become a reliable number for determining general beer ABVs.Įven if you love math, there’s only so much manual calculation one person can do in a day. This number comes from a chemistry equation that includes the density of ethanol and the number of ethanol grams generated per gram of carbon dioxide released. If you’re wondering why brewers use 131.25, we’ll offer a simplified explanation. ![]() Here is an example of what a real calculation could look like: (2.075 - 2.015) x 131.25 = 7.88% ABV (rounded up)Ī beer with this ABV would be on the higher side, but it’s no less possible. Here is the basic ABV formula: (Original gravity - final gravity) x 131.25 = alcohol by volume, as a percentage With these two numbers and the right formula, you can calculate your drink’s ABV. This shows how much the density has changed and is crucial to get an accurate ABV. When fermentation is complete, measure the final gravity (FG) of your alcohol. After taking note of your liquid’s OG, you can continue with fermentation. You can do this with a hydrometer, which is a tool that measures the gravity of a liquid. To get the right ABV, you need to measure your liquid’s original gravity (OG) before fermentation. The pyruvic acid molecules are then broken down into ethanol and 2CO2, or carbon dioxide. Yeast breaks down the sugar molecules into pyruvate molecules, which form pyruvic acid. This is done by adding yeast and the liquid to a fermentation vessel, like an oak barrel or stainless steel tank. ![]() In order to create alcohol, the sugar in a liquid must be converted to ethanol. Still, it helps to understand why we use it in the first place, and why the standard ABV calculation differs from the one for wine alcohol content. Calculating ABV is much simpler than it may sound. ![]()
