Beer style beer differently. Since sugars are converted to alcohol during the process of fermentation, gravity can be used to estimate the final alcohol. In beer brewing, a distinction is made between the "original gravity", the gravity of the wort before fermentation has begun, and the "final gravity" of the product when fermentation has completed. Since the concentration of sugars is directly proportional to the gravity, the original gravity gives a brewer an idea of the potential alcoholic strength of the final product. After fermentation, the differences between the final and original gravities indicates the amount of sugar converted into alcohol, allowing
F. & M. Schaefer Brewing Company 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.
