step 1: Put the Malt into the Malt miller; in this step can make the malt  fully mashed.

   step 2: Mix and stir the pulverized malt with 63-68° water, and use the enzymes contained in the malt to decompose the insoluble macromolecular substances (starch, protein, hemicellulose, etc.) in the malt and auxiliary materials into soluble low-molecular-weight substances. (eg sugars, dextrins, amino acids, peptides), in this step we can get the wort.

   step 3: The next step is Lauter. In this step, we need to add water at 78-82° twice to wash the wort. Then we will filter to get clear wort. This step can be observed through our sight glass.

   step 4: The next step is to boil and spin sink. Through this step, we sterilize the wort. The purpose of the spin sink is to precipitate the deteriorated protein in the wort, so that we can get a clearer wort.
