Pair with the RAPT-enabled Bluetooth Thermometer, allowing your BrewZilla to calculate a core mash temperature reading and more accurately control temperatures and mash steps
More RAPT-enabled accessories are coming, and future firmware updates can be downloaded to the RAPT Controller itself over the internet
WiFi/Bluetooth Enabled RAPT Controller
The RAPT Controller is mounted to the top of the boiler body, allowing for easy operation when you have the unit set on the ground. The controller can be tilted upwards to give you an even better view, or it can be removed from the BrewZilla entirely if you’d prefer to mount the controller on your wall or lay it down on a workbench. From the controller, you’ll orchestrate your entire brew day. Program mash steps, dial in element power, and operate the integrated pump all from one screen.
But the RAPT Controller is much more than a beautiful, full-color display switch board. Once synced to the RAPT Portal, you’ll be able to track, record and monitor your brews online. No need for handwriting notes or punching brew day details into your phone – all of the data from your brew is automatically logged to your portal profile. This information doesn’t just include your mash profile; it also captures detailed information about your element power and pump activity, opening the door for very precise repeatability.
And the RAPT Portal isn’t just a digital archive for your brew days. With your BrewZilla powered on, you can control your brewery from virtually anywhere using your phone’s web browser. Not sure when you’ll be home from work or your kid’s ball game going into extra innings? No problem! Before you head out, simply log into the RAPT Portal from your phone and tell the BrewZilla to start heating your strike water. Along with remote control, the portal enables you to program alarms and push notifications for all of your boil additions. We’ve all been caught up with a side task and failed to throw in that yeast nutrient or clarifying agent at the end of the boil, but the BrewZilla has the back of even the most forgetful brewer!
But wait, there’s more! In addition to WiFi connectivity, the RAPT Controller is also a Bluetooth gateway device. KegLand is currently developing various Bluetooth devices such as the Bluetooth Beacon Thermometer and other sensors which will be compatible with your brewery upon release. The RAPT Controller is able to receive information from Bluetooth Low Energy (BLE) devices, adjusting its processes based on this new stream of information while simultaneously logging it to your RAPT Portal. With the Bluetooth Beacon Thermometer, for example, you’ll be able to feed temperature readings from the top of your mash bed to the controller. The controller will then compare this reading with the main temp probe reading at the base of the kettle and adjust element cycling based on these combined readings.
Finally, the RAPT Controller WiFi connectivity allows you to update the controller’s firmware with a single click. Take advantage of new features and accessories as soon as they become available by simply keeping your BrewZilla connected to your local WiFi network. And again, the WiFi is already built-in! No need to come back for an expensive add-on accessory down the road.
Concave Base with Center Draining
Leave no wort behind! The concave base with center drain means you’ll be able to extract every last drop of wort to your fermenter. If you’ve brewed in a traditional flat bottom kettle, this center drain may be a bit perplexing at first. Many brewers are used to whirlpooling after the boil to pull hop matter into the center of the kettle, then transfer out using a pick-up tube that pulls from the kettle wall in order to avoid sucking up the solids. But fear not! One of the key features of the BrewZilla is the false bottom protection screen. This screen avoids the need for doing a whirlpool, filtering wort as it transfers and blocking more than 95% of hops and hot break from getting sucked into the pump. This not only prevents blocked pump issues, it also increases the efficiency of your brewhouse by eliminating kettle loss from wort that may have otherwise been left behind.
Ultra Low Watt Density Elements
The concave base on the BrewZilla also allowed for larger heating elements with significantly lower watt density than other breweries. When a lot of energy is coming off of a small element, the local temperature near the element can be so high that it scorches the wort and causes caramelization. Lower watt density essentially means you can produce lighter color beers that would otherwise have fallen victim to caramelization effect. It also reduces that chance of boilovers and reduces stress on the elements which extends their life expectancy.
Heat Exchanger Dish
The 100L BrewZilla comes standard with the Heat Exchanger Dish which redirects the flow of wort so that it spends more time exposed to the heating elements before reaching the center drain at the bottom of the kettle and being recirculated. Due to the concave bottom and central draining hole on the Gen 4 BrewZilla, recirculating wort will pass through the malt pipe and then down through the boiler false bottom following the path of least resistance. This can cause wort to make a B-line for the drainage hole and reduce the wort's exposure to the unit's heating elements. With the HED installed, wort will be directed to the edge of the BrewZilla base and pass over the elements for a longer period and reduce the time needed to heat to your set temperature. An optional accessory for the smaller units, but included as standard on the 100L BrewZilla.
Easy Access Built-In Pump
The built-in pump allows you to recirculate your wort during the mash for improved efficiency and more even temperature distribution. But it can also be used to transfer your wort from kettle to fermenter rather than relying on a gravity feed, and with the optional CIP Rotar, you can used the pump to clean your BrewZilla (or fermenter) after every use. During your brew day you’ll be able to control the pump from the RAPT Controller with a dedicated button for turning the pump on and off. Another feature you’ll find on the controller is adjusting the pump flow. This doesn’t control the actual volume of the flow (you can do that from the ball valve located on the recirculation arm), but rather cycles the pump on and off automatically based on your setting. At 100%, the pump remains on continuously. But at 80%, the pump will cycle to be on 80% of the time and off 20% of the time. This may not be a feature that every brewer thinks they need, but it’s an excellent way to avoid running the pump dry accidentally, as the time the pump is off allows recirculating wort to filter through the grain bed and back into the pump inlet.
If you flip over the boiler, you’ll find the magnetic drive pump and all the plumbing is right at your fingertips. This means you don’t have to disassemble the base in order to access the pump for cleaning or maintenance if required. It also means the plumbing can be changed more easily too. For instance, the unit comes as standard with the plumbing from the pump feeding both the recirculation arm and the transfer valve, but you change this so the tap outlet bypasses the pump if you prefer.
MoreBeer!'s Final Word
We’ve been selling all-in-one brewing systems ever since they first hit the market, and we have to say that the Gen 4 BrewZilla is not only the most feature-packed unit ever made, it’s also offered at an incredibly competitive price point when compared to other systems. You’ll get all of the cutting edge Bluetooth technology you’d get with the Grainfather and at an exceptionally lower price tag. Plus, you get the WiFi capabilities as standard, rather than as a $100 add-on accessory. When it comes to mash recirculation, that’s yet another built-in feature on the BrewZilla, and the pump can also be used for transferring and CIP cleaning. The Foundry has a great starting price, but if you want to unlock its full potential, you’ll need to spend another $100 for the recirculation pump kit. What’s more, no other system in the same ‘weight class’ has the same grain capacity. And if the standard capacity isn’t quite enough, the BrewZilla can be easily upgraded with a Boiler Body Extension Kit and Extended Malt Pipe. When you purchase the BrewZilla, you can feel confident that you’re investing in a top shelf system and all of the critical features you’re expecting will be included.

Please note: due to patent restrictions in the United States, the malt pipe has been redesigned with one set of bottom feet. This model does not include the "two stage" malt pipe as advertised by KegLand and featured in previous MoreBeer! YouTube videos.
Please Note: When removing the malt pipe to drain after mashing, it is important to do so slowly rather than in one swift pull. If the malt pipe is removed all at once when it is full of wort, it is possible for the draining wort to spray out and over the rim of the brewery through the perforated bottom. Remove the malt pipe slowly so that some of the wort can drain out before it is fully removed and set on its bottom feet. This can be done by hand on the 35L unit, but for the 65L and 100L units we highly recommend using the Pulley System for removing the malt pipe.
Warning: Do not engage the adjustable lid clamps when brewing with the BrewZilla's standard glass lid. The clamps are only intended to be used with distillation lids or other metal accessories. With too much tension, it is possible for the lid clamps to break the glass lid when engaged.
Warning: If you are going to use an extension cord with the BrewZilla, you must ensure that the cord is the correct gauge and properly rated to suit the power requirements of your brewery. See the reference chart below for the recommended gauge based on your unit and the length of cord you wish to use.
