The given illustration depicts how beer was produced.
From the data provided in the diagram, we can see that there are 12 steps for beer production. Firstly, it starts with the malt mill step, and finally, it ends with two choices: cleaning and bottling or cleaning and kegging.
First of all, the process starts with the malt mill, and after that, water is added, and the mash cooker step is completed. Then, the process is followed by the 3rd and 4th steps, which are the mash tun and lauter tun. After that, the wort copper part is started, and hops are added at that time. At the end of this part, the external kettle step is begun.
At step 7, the mixture is mixed, and after that, the wort cooler step is continued. At the end of this part, the mixture is put into a tank for fermentation, and it stays in the tank for a while. After that, the resting mixture is put into a filtration unit by the producers. And finally, the beer is produced, and it is ready for the final steps. They can serve the beer in two ways: bottling and kegging. After cleaning those two types of things, they fill that, and the process is over.
