How To Lauter The Wort 2

Now, let’s continue to talk about the wort recycling process.

Step 4: Recycle the wort.
After sitting for 10-20 minutes, the spent grain layer has formed and then, we need to recycle the wort to get a clear wort. Open the beer drain to expel the air from the pipe and close it. Then open the valve and deliver the wort to the percolation tank again, because the wort is very cloudy at the beginning. Note: The recycled wort must be returned to the fermenter below the wort level to prevent the recycled wort from damaging the spent grain layer and also to reduce the oxidation level. The cycle time is usually about 10 minutes until the wort brightens.

Step 5: Steaming of the first wort.
The first wort pull time is about 75-105 minutes.
After the recovered wort has brightened, open the inlet of the kettle chamber and let the wort in. At this stage, the rake can be opened to help lose the spent grain layer. 25-30 minutes later, the first wort concentration is tested to determine the amount of water to be refilled. For a proper wort concentration, the first wort concentration needs to be about 40-80% higher than the final concentration. If we need a 12P beer, the first wort concentration should ideally be 16-20P.
