During fermentation, the glucose is converted to carbon-dioxide and ethanol but, behind this simple concept is a series of complex biochemical reactions such as the ‘Glycolytic pathway’ involving various enzymes and the reactions take place anaerobically inside the cells of the brewing yeast. Beer processing involves series of steps starting from the reception of raw materials to the secondary fermentation and storage of the filtered and packaged …show more content…

(vii) Wort Cooling and Oxygenation
After whirlpooling, the clean wort is passed through a plate heat exchanger in order to cool the wort to 12-20⁰C. The, the wort is transferred to the fermentation tanks.
(viii) Fermentation
Yeast us injected inside and the sugars contained are then converted into alcohol and carbon-dioxide. The operation lasts for 3-10 days depending up on the type of the beer and percentage of alcohol desired in preparation. After the fermentation is finished, the tank temperature is cooled to 0⁰C. The yeast is extracted from the bottom of the tank before the final filtration. The yeast is stored and routed to farms for pig feed.
(ix) Maturation
The beer is pumped to the maturation tank and stored less than 4⁰C. Here, the beer finds its ‘delicacy’.
