Brewing System | BrewZilla Gen 4

Elevate your brewing game with the Gen 4 BrewZilla. This system combines features like wireless connectivity via WiFi & Bluetooth, allowing you to control and monitor your brew day, ensuring precision, convenience, and exceptional beer batch after batch.

• WiFi / Bluetooth enabled RAPT Controller tracks your brew day and automatically uploads detailed information to the RAPT portal.
• The top mounted RAPT Controller can be tilted upward for easy viewing, or detached from the unit to mount on the wall or place where you'd like it.
• Mirror polished dome shaped bottom with center drain let's you get every last bit of wort into your fermenter.
• Perforated bottom screen filters out 95% of hot break and trub.
• Make larger batches or higher gravity beers. BrewZilla offers a large malt pipe capacity, and the Gen 4 unit has a 30% larger malt pipe compared to the previous generation.
• Middle position feet allows you to lift out the malt pipe in two stages. Lift that heavy malt pipe to the middle position first, allow it to drain, then completely lift out the malt pipe for sparging.
• Perforated bottom on the malt pipe allows for improved mash recirculation flow without sacrificing efficiency.
• Element power percentage can be adjusted via the RAPT Controller. Go full power to heat up quickly, and dial it back as you approach your strike water temp
• The built-in pump is plumbed to both the recirculation and arm and the bottom ball valve. Recirculate wort during your mash, then close the recirculation valve and pump wort to your fermenter via the bottom valve.
• 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 place it elsewhere. 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.

The RAPT Controller's full-color display switch board syncs to the RAPT Portal, allowing you to track, record and monitor your brews online. No need to handwrite notes or punch brew day details into your phone. All of the data from your brew is automatically logged to your portal profile. Along with your mash profile; it also captures detailed information about your element power and pump activity, giving you the ability to recreate your brews very precisely.

In addition to the digital archive that the RAPT Portal provides,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? No problem. Before you head out, 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.

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.

High Capacity Malt Pipe

With an approximately 23.5 lb capacity, the BrewZilla can mash nearly 50% more grain than similar sized models of the Anvil Foundry and Grainfather G30. If you want to fill your fermenter with more than a 5-gallon batch worth of wort, or brew the highest gravity beer recipes, the BrewZilla can do it. If you want to expand your brewery’s grain capacity even further, KegLand makes Boiler Extension Kits and Extended Malt Pipes for that very purpose.

Other features on the BrewZilla malt pipe include the middle row of feet and perforated bottom. By adding a second row of feet to the malt pipe, you can remove it from the boiler in two stages. Take it to the middle row of feet for the initial lift, wait for the wort to drain, then lift it all the way out to completely drain the malt pipe and begin sparging. The malt pipe features a perforated section at the bottom which improves mash recirculation flow without sacrificing efficiency.

Concave Base with Center Draining

Leave no wort behind. The concave base with center drain allows you to extract every last drop of wort to your fermenter. 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 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 prevents blocked pump issues and increases the efficiency of your brew house by eliminating kettle loss from wort that may have otherwise been left behind.

Ultra Low Watt Density Elements

The concave base on the BrewZilla allows for larger heating elements with significantly lower watt density. Lower watt density means you can produce lighter color beers that would otherwise have fallen victim to caramelization effect. It also reduces chances of boil overs and reduces stress on the elements which extends their life expectancy.

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. 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 use 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, along with the ability to adjust 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 uses, 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, the magnetic drive pump and all the plumbing is easily accessible. You don’t have to disassemble the base in order to access the pump for cleaning or maintenance if required and the plumbing can be changed more easily. 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.

Final Notes

The Gen 4 BrewZilla is a feature-packed unit offered at a competitive price point. You get cutting edge Bluetooth technology, plus, you get the WiFi capabilities as standard. 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. 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.
