Beer can be traced back at least six thousand years, to the ancient civilization of Sumeria. A hymn, entitled “Hymn to Ninkasi,” which includes (translated): Ninkasi, you are the one who pours out the filtered beer of the collector vat. It is [like] the onrush of Tigris and Euphrates.
Padden believes that it was possibly found because the Mesopotamian natives never liked to waste food and that some bread or grain got wet, fermenting into an inebriating pile of mush. From this, this could have been the start of what we know now as beer. All beers are brewed using a process based on a simple formula. Key to the beer making process …show more content…
In order for the bitterness to be extracted from the hops the brew needs to boil for up to 90 minutes. Depending on what kind of beer one is making depends on how many hops are added. The hops are only to provide bitterness; aroma and flavor are added in another process, unless there are hops added 10-15 min before the brew is done then that would add to the flavor, but again depends on the beer one is making. Hops can be described as tea leaves, needing to have been soaked in hot water first to extract its oils and bitterness or else it adds nothing to the brew. The next step after the brewing process is complete is to separate all the solids. First the kettle is drained then added to a jet nozzle, the flow of liquid then creates a whirlpool. Now in a whirlpool all the hops and other solids move to the center. After about 20 minutes the particles move downward and start to solidify. After this the brew can be drained and cooled down to the proper temperature for the yeast. The machine used for this is the liquid-to-liquid heat exchanger. Through the machine there are two sets of tubes, one with the brew the other has cold water circulating through the other. A rather important part is
