Wort Sparging Process
Wort sparging is usually to make the water touch the surface of the spent grain bed within a certain time. During this process ,it could extract more substance from the spent grain bed.Usually the sparging process could be divided into 2 or 3 process.The first time sparging water amount is less about 20%,it could exclude the wort from the spent grain bed in the first time.The second time sparging water amount is about 50%,it could make the extract substance amount reduced smoothly.The third time sparging water amount is about 30%，it could make the extracted substance goes out from the spent grain further more.
The sparging water temperature is more high,the spent grain could be washed more fast.But the water temperature should be controlled within the mashing temperature,usually it is about 76-78°C，it is better that it will not surpass the 80°C.If the sparging water temperature is too low,it is not easy to wash the sugar from the spent grain out,it also is easy to get the bacteria.If the sparging water temperature is too high,it will make the amylase lose activity,and the it can’t go on decomposition of starch.In this case,it will reduce the utilization of the starch and deepen the wort color.
The sparging water amount is up to the first wort amount and density and the density of the full kettle tun wort,it has great influence on the wort yield
