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
F. & M. Schaefer Brewing Company early 60s. F. & M. Schaefer Brewing Company F. & M. Schaefer Brewing Company was a Manhattan brewing company. It was founded in 1842 by brothers Frederick Schaefer (1817-1897) and Maximilian Karl Emil Schaefer (1819–1904), natives of Wetzlar, Prussia, Germany. Frederick emigrated to the U.S. in 1838, followed by Maximilian in 1839. Maximilian brought the recipe for lager beer with him. After working for them, they saved up enough money to acquire the Sebastion Somers Brewing Company. How this was managed, and what brewing experience the pair brought from Germany, is unclear. What they did bring was a recipe for
