BrewZilla 35L Gen 4 Released

The BrewZilla Gen 4 is designed just like their older version to be a compact single vessel all grain home brewing system that can be run off a single 220-240v socket. A complete turnkey system with a delay timing feature and step mash functionality. Built to make batches up to 30L, it is the ideal solution for those who want to take the first step in all-grain brewing while also wanting full control of their batch from start to finish.

There are some key feature upgrades on the Gen 4 when compared to the older Gen 3. Here they are lending design features from other companies and the community. A normal DIY mod done by the community is for example moving the display up for a more ergonomic brewing experience (like the Grainfather).

The Brewzilla has been one of the most popular BIAB systems on the market, delivering great performance at a competitive price point when compared to the other systems that are available. I got the Brewzilla 3.1.1 for more than a year.

List of upgrades on the 35L BrewZilla Generation 4.0 and some features that differentiate this brewery

Kegland has made some big improvements on the design with their latest Brewzilla generation.

Complete Concave Draining Base

The new base design completely drains out meaning you capture every single bit of wort. The Brewzilla gen 3 has a flat bottom still this has not really been a big issue if you were using the pump to drain the wort.

If you were not using the pump then you had to tilt the brewery to extract every last bit of wort.  The concave draining bose makes it suitable for CIP cleaning using the new Low Volume CIP Spray Rotor (KL04329).

False Bottom Pump Protection Screen

The false bottom is not something new and has been a part of the BerwZilla generation for a while. It does work with whole hopes. Still, we recommend using a hop basket in addition to the false bottom for catching the hops.

One of the key features of all the BrewZilla single vessel units is the false bottom protection screen. This screen avoids the need for doing a whirlpool and it filters wort and prevents more than 95% of hops and hot breaks from getting sucked into the pump and thus greatly reduces the blocked pump issues that are often an issue with other brewery designs.

Ultra Low Watt Density

The BrewZilla has a significantly lower watt density than other breweries.  The main benefit of lower watt densities is that it enables you to produce lighter colours of beers that would otherwise get some caramelisation. 

The ultra-low watt density also means you have less chance of boilovers, you get less crud sticking to the element making cleaning easier and ultimately reducing wear and tear on the element meaning even with significant abuse your elements will last way longer.

RAPT/Wifi Connected

The new Gen 4 model is the first BrewZilla that connects to the RAPT Portal (  This portal allows you to track, record and monitor your brews online.  This greatly reduces the need for handwritten records of your brew day as it’s all done automatically.  The RAPT portal also allows you to see every brew you have done in the past and control the brewery remotely so you can start pre-heating water remotely or simply keep an eye on the brewing process while you do something else.  Get push notifications to your mobile phone of when to add hops or start the boil.  

Along with this ease of access and control. The RAPT BrewZilla will also allow you to fully customise your brew day with profiles specifically tuned to your style of brewing or your recipe.

For example, you could set up your profile to receive certain alarms or messages when you are required to do something. E.g. Adding grain when the strike temperature is reached. Mash-Out Alarm when you’re ready to sparge, Salt / Hop additions when you’ve reached the boil. As well as hop stand additions or chilling instructions. All of this at the touch of a button that is preprogrammed to what you want to do. No more egg timers, no more phone timers. Everything is controlled by one area.

Bluetooth Gateway Device

KegLand is currently developing various Bluetooth devices such as Bluetooth low energy (BLE) thermometers and other sensors which will be compatible with this brewery.  This brewery is able to receive the BLE beacons and relay this information onto the RAPT portal. 

Also by receiving multiple BLE thermometer sensors the Brewery is able to make smarter and more automated decisions on how to control the brewing or distillation process.  For example, a BLE thermometer can be placed into your coolant water so you get an alarm if the temperature is too high, a BLE thermometer can be put into the middle of the malt pipe so you can more accurately control elements switching on/off to achieve a core malt pipe temperature etc.

Improved Base Design with Easy Access Pump

There are numerous instances where the pump or tubing could clog up. IN the older generation you had to turn the boiler around and unscrew a couple of screws to get to the pump and plumping. Exposing both the pump and electronics.

The new base design means we have sealed all the electronics on the underside of the brewery into a separate junction box. This has removed the need for a bottom cover making so that the pump can be accessed much more easily. 

It also means the plumbing can be changed more easily too. For instance, you can re-arrange the plumping to the pump to pump into the tap outlet or change this so the tap outlet bypasses the pump.  These changes make it more flexible but also much easier to take apart the pump for cleaning and maintenance if required.

RAPT Controller with Full Colour Screen

The new RAPT controller has an easy to read full-colour screen. The controller can also be disconnected easily making washing down easier.  The controller is mounted in a higher position with a tilting frame so you can angle the screen toward you depending on how tall you are. 

The new controller module is packed with features and KegLand is consistently updating the firmware to include more features.  Firmware updates are quick and painless and with a single click, you can upgrade all Gen 4 units to the latest firmware to take advantage of new features and accessories. Forget getting on your knees mid-brew, do it all while standing or sitting next to your BrewZilla.

The controller can also activate the pump. Meaning there are no toggle switches anywhere on the BrewZilla Gen 4.

IEC Cable for Easy Storage

The new design has a removable IEC cable so you can unplug the cable making it neater for storage. This is a welcome feature as the whole point of BIAB and kettles like the BrewZilla are that they should be space-saving compared to 3 vessel herms.

Improved Lid Handles

The new lid handles are better designed and made from stainless so they are more robust and more ergonomic to hold especially with wet hands. The hold was just two small plastic knobs that you easily could slip.

Two Stage Oversized Malt Pipe

This new malt pipe design is 30% larger meaning you can mash more grains and either make more beer or make higher gravity beers.  The new malt pipe also has a two-stage height adjustment so you hand half lift the malt pipe and set it on the supporting halo ring halfway up. 

This makes it more ergonomic so you can lift the heavy malt pipe up in two stages but has the second advantage that it makes the brewery more suitable for smaller batches too where raising the malt pipe halfway up is preferable.
