All-in-one brewer or electric mash kettle
An electric brewing vessel that combines controlled heating with a removable grain basket and, on the documented models, a recirculation pump for mashing and boiling wort.

Grainfather G30 all-in-one brewer
A 30-litre stainless electric all-grain brewing system with a removable grain basket, controlled heat, pump-driven wort recirculation and counterflow chilling. Electrical ratings and controls vary by revision.
One vessel for the hot side of brewing
The G30 combines an electric boiler and removable perforated grain basket in a single homebrewing system. During an all-grain brew, the basket holds crushed malt while heated water circulates through the grain bed. After the mash and sparge, the brewer lifts out the basket and boils the wort in the same boiler. The maker's instructions describe a pump and recirculation pipe for mashing, followed by a counterflow chiller for cooling the wort.
The name covers more than one revision. Grainfather's support centre lists separate instructions for the G30, G30³ and original non-Bluetooth model, while its showcase depicts the G30 v3. Photographs and specifications from one revision should not be silently transferred to another.
Capacity, heat and control
The G30 is a nominal 30-litre system. That is vessel capacity, not a promise of finished beer volume: grain load, boil-off and the recipe determine what can be collected. The cited instructions specify a stainless boiler, extendable grain basket, independently switched pump and programmable mash steps. Grainfather's support article explains a manual heat-output mode for the 1,600-watt version: 65 percent corresponds to 1,040 watts and 75 percent to 1,200 watts. Those examples do not apply to the 2,000-watt 220–240-volt model.
The manual warns that proteins may collect on the base as boiling begins and can trigger the boil-dry cut-out. It tells the brewer to scrape the element lightly with a paddle. The appliance's probe reports the boiler's reading; it does not establish the temperature at every point in a grain bed.
Origins and limits of the record
Bevie's company timeline says the Grainfather concept began in 2013 and Imake launched the system in New Zealand in 2014. Grainfather also says the G30 began in New Zealand. These company-origin and launch statements do not identify a factory or manufacturing location.
The maker documents the G30 for small-batch beer brewing. These sources do not validate using it as a cheese vat or dairy water bath. The related all-in-one brewer page covers the broader equipment class; this page records one model with its own power, capacity and revision-specific instructions.

History
Bevie dates the Grainfather concept to 2013 and says Imake launched it in New Zealand in 2014. This documents launch history, not a manufacturing address or the invention date of all-in-one brewers.
Equipment details
CapacityNominal boiler capacity is 30 L (about 7.9 US gal), not a finished-batch guarantee. Grain load and batch volume depend on the G30 revision and supplied pipework.
PowerElectric The G30 manual lists 2,000 W at 220–240 V or 1,600 W at 110–120 V. The support article's percentage examples are specifically for the 1,600 W version.
How you get oneBought, manufactured A complete small-batch all-grain beer brewing appliance. Check the exact generation and voltage against its manual.
CareClean the boiler, pump and circulation path after brewing as the manual directs. Grainfather recommends dismantling and cleaning the valve assembly, using a suitable alkaline stainless-steel cleaner and avoiding chlorine-based cleaners.
Made of
- 304-grade stainless steel — Boiler body
The G30 system also includes a removable perforated grain basket, controller, pump and recirculation fittings.
Risks and precautions
Hot liquid and surfaces
The G30 manual warns that the boiler, lid and pipes can reach 100 °C, and says not to move it while operating.
Hazard sourceUse on a flat, stable surface; follow the manual for the basket, circulation path and cooling hoses. Unplug before cleaning; do not immerse cord or plugs.
Control sourceThe maker documents the G30 for small-batch beer brewing. Other food uses, including dairy water-bath adaptations, are not validated by these sources.
Limits
The manual identifies small-batch beer brewing as intended use and says to use the unit only for that purpose; it does not validate dairy or other food adaptations.
