The diagram illustrates details about the process by which bottled beer is produced.
Overall, the process is divided into eight phases, beginning with the malting of barley and ending with the production of bottled beer, which is relatively complex and involves various types of machinery.
In the initial stages, barley is first allowed to germinate, producing malt, which serves as the foundation for beer, before undergoing a crushing stage, during which malt is ground into smaller pieces. In the third stage, after being crushed, the malt is filtered using water to remove any solid impurities and extract the malt liquid used in brewing.
Following that, the filtered liquid is boiled together with hops, which add aroma and flavor to the mixture. Next, the boiled liquid is cooled before being filled into fermentation barrels, where it ripens and develops alcohol content. After fermentation, the beer undergoes a second round of filtration to ensure clarity and purity. Eventually, the finished product is bottled and sealed, ready to be distributed for sale and consumption.
