The method for adding hops in the step 8 specifically includes:

During the liquid heating phase, the selected liquid does not flow through the hops or through the malt: even if the outlet tube is above the water passage through the cavity;

After the liquid is heated to the temperature required for the malt soaking, the liquid discharge tube is rotated back and forth over the upper space outside the hop container without passing through the hop container, keeping the water liquid flowing only through the malt without passing through the hop ;

Maintaining the temperature of the liquid at the temperature required for malt soaking, ensuring that the liquid discharge tube only rotates in the area of the upper space outside the hop container;

When the malt soaking time arrives, it enters the boiling stage. At this stage, the liquid outlet tube is kept rotated above the hop container, and according to different needs of the user, different hop storage chambers are selected at corresponding time periods; at this stage, the remaining The high temperature liquid no longer flows through the malt, but flows through the hop; the boiled liquid passes through the hop storage chamber around the upper space and directly into the lower space to avoid the malt.
A beer brewing method, comprising:

Beer brewing saccharification heating and fermentation, the beer brewing saccharification heating comprises the following steps:

Step 1, pouring a predetermined volume of normal temperature purified water into the saccharification vessel, opening the first pump to pump the water in the saccharification vessel from the bottom thereof to the heating unit;

Step 2, turning on the power of the heating unit to cause the heating unit to generate heat, thereby heating the liquid flowing through the heating unit, and the liquid passing through the heating unit flows back to the saccharification container;

Step 3, after the temperature of the liquid in the saccharification container reaches the temperature required for the malt feeding, a predetermined amount of malt is put into the saccharification capacity. In the device;

Step 4, continue to keep the heating unit in operation, so that the temperature of the liquid reaches the temperature required for the malt soaking;

Step 5, after the liquid in the saccharification container reaches the predetermined temperature of the malt immersion, the wort is soaked in the saccharification container for a certain time at the temperature for saccharification; in the process, the first pump is still kept open. So that the liquid in the saccharification vessel is in a state of flowing from top to bottom while maintaining the liquid in the saccharification vessel at a set temperature by controlling the time of the heating unit being turned on and off;

Step 6. Boiling stage: continuing to heat the wort in the saccharification vessel until the desired temperature is boiled, and still adopting the above-described method of circulating heating of the water stream for a predetermined time, so that the wort in the entire saccharification vessel is heated uniformly;

Step 7, after the wort is cooled, it is sent to the fermentation vessel;

Fermentation of beer brewing.
The method according to claim 29, wherein step 4 - step 5 can be repeated a plurality of times according to different needs of the user to realize stepwise multiple heating soaking.
The method of claim 30, further comprising the step of adding hops during said step 6.
The method of claim 31, further comprising the step of sampling the test sugar content after the boiling has ended.
The method of claim 32, further comprising the step of removing the wheat kernels after said step 5.
