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.
Equipment · All-in-one appliances
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.
From grain to wort in one vessel
An all-in-one brewer brings several hot-side brewing jobs into one electric vessel. Water is heated for the mash, crushed grain sits in a removable basket, and the resulting wort is brought to a boil after the grain has been removed. A controller sets the heating programme; a pump on the documented models circulates liquid through the system.
The brewing vessel is one piece of equipment within a larger process. Fermentation and cold maturation still need suitable containers and conditions of their own. The appliance name does not mean that beer goes from dry grain to finished drink without other handling, cleaning or storage.
The class and the individual model
The Grainfather G30 and BrewZilla 35 L Gen 4 illustrate the class without defining every product sold under the same description. Vessel volume, grain capacity, electrical supply, heating power, basket arrangement and controller functions belong to the particular model. A nominal vessel volume should not be read as the finished batch volume.
The model examples recorded here are the nominal 30 L G30 and 35 L BrewZilla. Their capacities are useful points of comparison, rather than a minimum or maximum for all electric brewers. Before attaching an appliance to a recipe, compare that recipe’s water and grain loads with the specifications of the actual unit.
Heating and measurement
An electric element heats the liquid from the base. The controller receives a reading from a probe in the appliance; that location matters when interpreting the number on its display. The BrewZilla instructions specifically distinguish that reading from the core temperature of the mash and recommend a second calibrated thermometer.
A temperature setting therefore describes the equipment’s control target. It is not a measurement of every part of a grain bed, nor an independently established condition in a second container placed inside the boiler. Recipe conditions and the equipment’s own operating limits remain separate information.
Where the equipment fits
An all-grain beer recipe gives this appliance class a clear job: heat the mash water, support the grain-handling stage and boil the wort. The equipment link identifies that role. It does not assert that a source recipe used one named brand, or that every brewer is large enough for every batch.
Owners also adapt brewing kettles for other food work, but the manuals cited here document brewing. A different food, a nested vessel or a long holding stage changes what needs to be assessed. The manufacturer’s minimum liquid level, pump connections, electrical requirements and instructions for handling hot liquid still apply.
History
The documented Grainfather G30 and BrewZilla Gen 4 are designed for small-batch beer brewing. Their manuals establish current equipment features; they do not establish when the all-in-one brewer was first invented.
Equipment details
CapacityThe documented examples are the nominal 30 L Grainfather G30 and 35 L BrewZilla Gen 4. Nominal vessel volume is not the finished batch volume.
PowerElectric G30 examples: 2,000 W at 220–240 V or 1,600 W at 110–120 V. The documented BrewZilla 35 L Gen 4 is 2,400 W. These are model specifications, not a rating shared by every brewer.
How you get oneBought, manufactured Sold as a complete small-batch beer-brewing appliance. Check the exact model and its manual before adapting it to another task.
CareFollow the cleaning and storage instructions for the exact model, including the boiler base, pump and circulation path. Equipment designed for wort does not acquire a validated cleaning process for another food merely by being rinsed.
Made of
- Stainless-steel kettle — Liquid vessel
An electric base element, controller and, on the documented models, a recirculation pump.
Risks and precautions
Hot surfaces and liquid
G30: boiler, lid and pipes reach up to 100 °C; never move the unit while it is operating.
Hazard sourceBrewZilla: do not boil dry or energise with less than 4 litres; never run the pump or energise without the recirculation arm connected (risk of spraying hot wort); never lift the unit when full; use only recommended cleaners.
Control sourceThe maker-documented purpose is beer brewing. Dairy and other food uses below are adaptations, not manufacturer-validated processes.
Limits
The BrewZilla manual warns that the controller reading is not the core temperature of the mash and recommends a second calibrated thermometer.
Source →The documented BrewZilla must not be energised with less than 4 litres in the boiler or run dry.
Source →The documented purpose is beer brewing. Other food uses are adaptations and require their own equipment and process assessment.
