WebNov 14, 2024 · The OG is the beer’s original gravity, and the FG is its final gravity. To calculate the Recipe Potential Original Gravity, multiply the post-boil volume in a gallon of liquid by the GU. When determining the alcohol content of an alcoholic beverage, an OG can be calculated in conjunction with the ABV formula. WebApr 9, 2024 · Original gravity (abbreviated OG) is a measure of the fermentable and un-fermentable substances in a beer wort before fermentation. Those substances are often the sugars that will be converted to alcohol during the fermentation process. OG gives the brewer an idea of the potential alcohol content in the final product.

If you had a 1.040 beer and achieved 100% real attenuation — in other words, if the yeast consumed all the sugars (and other solids) in the wort, leaving only water and ethanol — the final gravity of the beer, as measured by a hydrometer, would be about 0.991.
