Final Degree Of Attenuation

final degree of attenuation.

    The maximum apparent attenuation attainable by a particular wort as determined in a laboratory. The final attenuation depends above all on the proportion of fermentable sugars in the wort, most of which have been transformed before bottling to avoid biological reactions that affect the flavor, head retention, and stability of the beer. Syn: limit attenuation; final attenuation; attenuation final.

          Formula: A = (B-b) x 100

          A = final degree of attenuation

          B = original gravity in °B (or °P)

          b =   final gravity in °B (or °P)
