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
Brewing Industry Research Foundation Masson Gulland was killed in a train crash before taking up his position and hence Sir Ian Heilbron (Imperial College London) agreed to become the second Director of Research at the new Brewing Industry Research Foundation (BIRF)in 1949. In 1948 Lyttel Hall, Nutfield in Surrey was purchased and the main Hall was converted into laboratories, the squash court into a pilot brewery and other new buildings were developed as a workshops and conference facilities. In 1951 HRH The Duke of Edinburgh Prince Philip formally opened the site. BIRF later became The Brewing Research Foundation, BRF International, Brewing Research International and
