It appears that the boys at PicoBrew applied for and were granted patents on most of its design. I am certain that a patent attorney could find loopholes, but it looks like they own this market for the foreseeable future. These patents are very broad. I have not found the patent number for the last patent application.
Automated beer brewing system with vessel for brewing and fermenting
Patent number: 9109192
Abstract: A beer making system may use a detachable vessel to contain liquid during the mashing and boiling steps, and may also be used during the fermentation steps of beer making. The beer making system may recirculate liquid through the vessel, then select between several flow paths during the beer making process. A removable reservoir system having a grain reservoir and several hops or adjunct reservoirs may be selected as a flow path, as well as a bypass flow path. A programmable controller may cause liquid to recirculate through a heater and one of the various flow paths, the sequence, timing, and temperature profile of which are defined in a recipe for a particular beer.

Multiple flow path recirculating brewing system with removable reservoirs
Patent number: 9102908
Abstract: A beer making device may have removable reservoirs through which brewing ingredients may be added. The removable reservoir may include a grain steeping reservoir and one or more adjunct or hops steeping reservoirs. A removable tub may contain the various reservoirs, and some or all of the various ingredient reservoirs may be removable from the reservoir tub. For example, a set of hops reservoirs may be manufactured as a single joined unit, and may be removable from the reservoir tub. The removable reservoirs may include a check valve which may shut off flow when the reservoir may be removed or dislodged, thereby minimizing leakage, and a beer making device may further sense such a situation and cause operations to cease.

Cascading Hops Reservoirs for Recirculating Brewing System
Application number: 20150000532
Abstract: A cascading hops reservoir may have a series of hops or adjunct reservoirs, each having a drain and an overflow. The series of reservoirs may be used by causing flow through a first reservoir, which may cause liquid to flow through the reservoir and through the drain, as well as past an overflow. When a second set of hops or adjuncts may be added, the flow may be introduced to a second reservoir, which may flow through a drain and also overflow into the first reservoir. A series of multiple reservoirs may thus be used to introduce hops or other adjuncts into a brewing cycle in stages, with each additional stage including previous stages in the recirculating flow during the brewing cycle.
