System and method for all-in-one wort preparation

A brewing system comprising:

• a cooking vessel configured to heat a liquid in the cooking vessel;
• a grain container having a false bottom, wherein the grain container is configured to hold a grain bed, wherein the grain container includes a plurality of sieves that are configured to separate the grain bed into a plurality of vertically stacked grain layers, wherein each of the plurality of sieves is configured to allow wort to pass through and to hold back residual grain, wherein the plurality of sieves includes a first sieve and a second sieve arranged directly above the first sieve, and wherein the plurality of grain layers includes a first grain layer supported by the first sieve and a second grain layer supported by the second sieve;
• and
• a liquid-circulation system configured to:
• transfer the liquid heated by the cooking vessel directly into the grain container such that the transferred liquid contacts a top surface of the grain bed, filters through the grain bed and the plurality of sieves including through the second grain layer and the second sieve and then directly through the first grain layer and the first sieve,
• transfer the liquid that filtered through the grain bed and the plurality of sieves out of the grain container such that the liquid exits the grain container through the false bottom of the grain container, and
• transfer the liquid that exited through the false bottom of the grain container into the cooking vessel.
