Abstract: A method for combined production of beer and a non-fermented beverage from grain material makes use of a by-product in the beer production to produce the non-fermented beverage and thereby improves resource-efficiency. The method comprises processing the grain material into a mash; separating the mash into a fermentable wort and a retentate; processing a retentate material into a slurry, wherein the retentate material comprises at least a portion of the retentate; separating the slurry into a liquid component and a solid component; processing the liquid component into the non-fermented beverage; processing the fermentable wort into the beer; outputting the non-fermented beverage; and outputting the beer.

Abstract: The present invention relates to a method (300) for reducing an amount of microorganisms in brewers spent grains (BSG). The method (300) comprises feeding (S305) a liquid (120) and the BSG (110) into a mixing arrangement (130), mixing (S310), by means of the mixing arrangement (130), the liquid (120) and the BSG to form a mixture, feeding (S330) the mixture into a heat exchanger (140), and heating (S335), by means of the heat exchanger (140), the mixture for a predetermined period of time at a predetermined temperature such that the amount of microorganisms in the BSG (110) is reduced.
