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
