Abstract

A process of mashing grain into fermentable sugar wherein two pots are used in the process. A first pot and a second pot is partially filled with water. Heat is added to the first pot. Heat is transferred to the second pot by transferring the water from the first pot to the second pot at a preestablished rate. Grain is added to the second pot which in conjunction with the water forms a wort. The wort is drained from the second pot to the first pot.

Claims (13)

1. A two pot system for mashing grain into fermentable sugars, comprising:

(a) a first pot that is a mash tun; and

(b) a second pot that is a boil kettle; said boil kettle having (i) an open top, (ii) a closed bottom, and (iii) a lid positioned in physical contacting relationship with the open top of said boil kettle; wherein said mash tun has (i) a closed bottom and (ii) a filter system, the mash tun's closed bottom being in physical contacting relationship with said lid of the boil kettle;

(c) a drain line communicating from said mash tun near the closed bottom of the mash tun into said boil kettle;

(d) a flow control mechanism positioned in said drain line; and

(e) a heating unit transferring heat to said boil kettle.

2. The two pot system for mashing grain into fermentable sugar of claim 1 wherein said drain line is connected to a valve positioned in an outlet of the mash tun.

3. The two pot system for mashing grain into fermentable sugar of claim 1 wherein said mash tun includes a filter system.

4. The two pot system of claim 3 wherein the filter system includes a false bottom.

5. The two pot system of claim 1 further comprising a pump mechanism.

6. The two pot system of claim 5 wherein the pump mechanism includes an electronic controller.
