The provided diagram illustrates the process of how been is manufactured.
In general, the process consists of three key stages, including processing, packaging and delivering. It begins with the milling of malted barley and culminating with the delivery of beer to customers.
According to the diagram, we can see the initial stage is that the milling of malted barley, which is broken down into small pieces. After that, the ingredients are mashed with the addition of water. Then, the mixture is lautened, a process that results in spent grain, which is used as animal feed. In the next stage, the ingredients are placed into high-temperature water with addition of malt sugar and hops. Thereafter, the mixture is transferred into a whirlpool, including yeast one added; fermentation occurs, which emits CO2 and separates the yeast.
Furthermore, the penultimate stage involves filtering the been. Finally, the been is packed into bottles and cans before being delivered to the market.
