![]() ![]() Apparent Attenuation and Real AttenuationĪttenuation is the term used to describe the percent of sugar consumed by the yeast and turned into Alcohol, CO 2 and other compounds. So, if you are brewing strong beer, the difference becomes relevant. The Most Accurate ABV formula takes into account that the fluid measured in the Final Gravity is no longer only water with dissolved solids since it now contains alcohol. However, this formula becomes less accurate with progressively higher alcohol content. This works fine for most common beer types. The Simple ABV formula is used by most online ABV Calculators and is as follows: There are calculators to correct this, but even with a correction a calibrated Hydrometer is more accurate. Note that once fermentation begins and alcohol is present, refractometers become increasingly inaccurate. Degrees Brix (☋x) from a refractometer can be more accurately converted to Specific Gravity with this calculator: Degrees Brix To Specific Gravity Calculator. ![]() Degress Brix (☋x) and Degrees Plato (°P) are very close to one another, so they’re often used interchangeably. See the Hydrometer Temperature Correction Calculator for more information.Īlternatively, a refractometer measuring in Degrees Brix (☋x) can be used to get the Original Gravity/Extract reading. If you take Original Gravity (OG) and Final Gravity (FG) at similar temperatures somewhere around the hydrometer calibration point, there’s no need for a temperature correction. The Original Gravity (OG) and Final Gravity (FG) readings input into the calculator are usually taken with a Hydrometer. ![]() This is a calculator to accurately predict Alcohol By Volume for homebrewed beer. ![]()
