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.

KegLand BrewZilla 35 L Gen 4.1
A 35-litre all-in-one electric brewing system with a malt pipe, pump, concave base and RAPT controller. KegLand lists 2,400 W and batches of about 25 litres; its manual specifies a 4-litre minimum fill.
A single-vessel all-grain system
The BrewZilla Gen 4.1 is a 35-litre electric brewing system built around a stainless boiler and removable malt pipe. Grain sits in the malt pipe during the mash; a pump and recirculation arm return wort over the grain, after which the pipe is raised for sparging and removed before the boil. KegLand lists a maximum boiler capacity of 35 L and recommends the model for single batches of approximately 25 L.
The Gen 4.1 kit includes a false bottom in the boiler, a two-stage malt pipe, glass lid, pump, recirculation arm, RAPT Wi-Fi controller and immersion chiller. The false bottom sits roughly 14 mm above the concave boiler base and screens solids from the pump. The manual cautions that this screen is not a support for grain or a pot; the malt pipe carries the grain.
Heating and the temperature reading
KegLand lists 2,400 W for the 35 L model and describes low-watt-density elements. Its controller can be operated locally, while the RAPT system adds Wi-Fi monitoring and control. The manual says the controller probe measures liquid at the bottom of the boiler near the elements, not the core of the mash. Recirculation can bring the mash closer to the displayed temperature over time; for a direct check, the manual advises using a second calibrated thermometer in the mash.
When PID control is disabled, the manual suggests starting with 30–40 percent heating power during the mash to limit overshoot, while warning that the right setting depends on the grain bill, insulation and heat loss. That is model guidance, not a universal mash setting.
Operating limits and model boundaries
The manual sets a minimum fill of 4 L: do not energise the boiler or start a remote profile below that level. It also says to connect the recirculation arm before operating the pump, avoid running the pump dry and never lift the vessel when full. These constraints matter when comparing the BrewZilla with a generic electric kettle or considering any nested-vessel adaptation.
The Gen 4.1 product page identifies a concave base, low-profile false bottom, PPSU sight glass and adjustable clamps as Gen 4.1 features. The clamps must not be used to secure the included glass lid. The manufacturer's sources describe beer brewing; they do not validate the BrewZilla as a cheese vat, dairy bath or other food process. Its relationship to the general all-in-one brewer entry is a specific model-to-class link.
History
KegLand's current product page and the Gen 4.1 manual document a modern home-brewing system; neither source establishes when all-in-one brewers were first invented.
Equipment details
CapacityKegLand lists a 35 L maximum boiler capacity and says the system is ideally suited to single batches up to approximately 25 L. These figures describe the 35 L model, not every BrewZilla size.
PowerElectric The KegLand 35 L Gen 4.1 product page lists 2,400 W. Electrical version and market requirements vary; confirm the specific unit and outlet before use.
How you get oneBought, manufactured A complete single-vessel home all-grain brewing appliance sold as the BrewZilla 35 L Gen 4/4.1.
CareFollow the model manual for cleaning after brewing and for pump maintenance. Use only the cleaners and sanitisers it recommends; do not direct mains water down the pump inlet or recirculation pipe.
Made of
- Stainless steel — Boiler, malt pipe and false bottom
The product includes a boiler with concave base, a two-stage malt pipe, perforated screens, pump, recirculation arm and removable controller.
Risks and precautions
Hot wort and electrical heating
The manual warns that operating the pump or energising the unit without the recirculation arm securely connected can spray hot wort; it also says never to run dry or lift the full unit.
Hazard sourceKeep at least 4 L of liquid in the boiler before energising; connect the recirculation arm whenever the pump is used; do not run the pump dry or lift the full vessel.
Control sourceThe maker documents the BrewZilla as an all-grain beer-brewing system. These sources do not validate dairy or other food adaptations.
Limits
Do not energise with less than 4 L of liquid in the boiler; this is the manual's minimum fill, not a recommended small-batch recipe volume.
Source →The false bottom filters solids to protect the pump but is not designed to support grain or the weight of a pot.
Source →The controller probe reads liquid near the heating elements, not the mash core. The manual recommends a secondary calibrated thermometer for mash temperature.
