## Abstract

Included is a brewing system that utilizes a curved pedestal that allows brewed effluent to drain in a manner that travels toward the center of the curved pedestal to maximize the exposure of the effluent to the organic material used for brewing, while also maximizing yield. The pedestal 112 sits above the lowest effluent level to allow the brewed effluent to drain from the organic material that is used for brewing to maximize the amount of effluent obtained. By allowing the brewed effluent to drain from the organic material, the weight and size of the organic material is reduced, so that the filter bag can be removed from the brewing system without ripping or tearing. The brewing system eliminates the need for a separate mesh bag and allows the effluent to drain without squeezing the filter bag and which would otherwise cause the release of harsh oils and acids, which can also be unsanitary as a result of a user handling the bag filter.

## Claims

### Claim 1

A brewing system for brewing brewed effluent comprising:
a bucket that holds said brewed effluent;
a faucet disposed in a wall of said bucket in a location that is near a bottom portion of said bucket so that said brewed effluent can be drained to a minimum effluent level using said faucet, which leaves a space between said bottom portion of said bucket and said minimum effluent level for collection of undesirable sediment;
a pedestal that has a curved surface and holes formed in said curved surface, said curved surface slanted downwardly towards a center portion of said pedestal, said curved surface having a curvature that is sufficient to allow said pedestal to not interfere with said faucet and remain above said minimum effluent level of a central portion of said curved surface;
a filter bag that contains an organic material for brewing, said filter bag disposed on said curved surface of said pedestal so that said brewed effluent drains towards said central portion of said curved surface and said filter bag can fully drain, which reduces the weight of said organic material, so that said filter bag does not tear when being removed from said bucket.

### Claim 2 (depends on 1)

The system of claim 1 wherein said filter bag is constructed of a paper filter and there is no net bag surrounding said filter bag.

### Claim 3 (depends on 2)

The system of claim 2 wherein said pedestal is a food grade material and does not float.

### Claim 4 (depends on 3)

The system of claim 3 wherein said pedestal has at least three legs that form recessed openings at locations where said legs meet said curved surface, said recesses being sufficiently large to allow a user to insert a finger for removal of said pedestal from said bucket.
