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
National Brewing Company two companies would result in a monopoly, denied the merger. Merely three years later, Carling-National was sold to G. Heileman Brewing Company of La Crosse, Wisconsin and the former brewing facility of Brewer's Hill was closed. Stroh Brewery Company of Detroit, Michigan later bought over the rights from Heileman in 1996. National Bohemian beer has not been brewed in Baltimore since. As of today, the brewery has been converted to business and office spaces as a part of the Brewers Hill redevelopment project by Obrecht Commercial Real Estate. National Bohemian, now only “National” in name, is brewed in North Carolina
