Attenuation (brewing) Attenuation (brewing) In brewing, attenuation is the percentage that measures the conversion of sugars into alcohol and carbon dioxide by the fermentation process; a more attenuated beer will generally be drier and more alcoholic than a less attenuated beer made from the same wort. The percentage is calculated by comparing weight or specific gravity of the extract before and after fermentation. the following iteration,Attenuation = 100 % * (starting gravity − current gravity) / (starting gravity − 1) is meaningless This formula works with extract given in weight percentages or degree Plato. Extract refers to all the non water substances
