Thanks for the run down. We really appreciate it! Keep up the great work on the channel.

I took a long time deciding on whether to buy an all and waiting for one that fit all my requirements. I finally bought one when the gen 4 Brewzilla was released. To me the main benefit isn't the high up controller (although that is good for the back I guess), but rather - Centre drain, so easy to clean, no need to tip it to get all the liquid out. - Tiny dead space under the false bottom, allows not only a bigger grain bill but also a smaller one. I did a 5 litre batch the other day which would be very difficult on other all in ones. - Expandability. Touched upon in the video, but if at a future point I wanted to do a double batch I can buy a couple of extenders. They also do an extended malt pipe if I wanted to use even more grain. - Bluetooth integrations. They have a Bluetooth temperature probe coming out which will allow for the core mash temp to be monitored (rather than the liquid in the base) and for this to be the temperature that is being controlled. If you were selling them if have bought it from you for sure, but had to go elsewhere for this purchase!

I have ver3 for about 120 brews. Works good. If I want a system again I will buy ver4. I love it!

This looks to have addressed all of the issues I have encountered with the gen 3 that I use. 1) Regular pump failures were a pain because of small pipe bores and inaccessible pump. I gave up using the pump. Bigger diameter pipes here and what looks like a more robust and certainly a more accessible one. 2) love the look of the conical bottom. The gen 3 has a large amount of dead space (wasted beer). 3) glad to see the sturdy handles on the lid. One of the flimsy knobs on my gen 3 snapped off early. Looks like a great machine now.

I have brewed with the Gen 3.1 for a couple of years now and have to say it is great. I have had no issue with the false bottom. The controller was in an awkward place so it's goo to see that they moved it. I don't think I would upgrade to the Gen 4, however, if my Gen 3 were to give up I would defintely go for the gen 4.

I have an older generation Brewzilla, and really enjoy brewing with it. The false bottom IMO is too flimsy though and has suffered some damage over time. I’ve now bought their heavy duty false bottom which is a great upgrade and I’d like to see KL supply this with the Zilla as the standard version.

I will be buying one of these as my first all grain brewing system. Probably early new year. Hopefully you’ll be stocking them by then.

Happy with my Beacon 40 but the small dead space on this unit looks really appealing.

I just wanted to say that this looks really good for the price and I like the idea of the extendable boiler. I suspect that the 30L version will far out sell the 65L version as that one needs a dedicated 15A circuit (the UK only has 13A max), you will need to get an electrician to put a 15A supply into your consumer box to power it. Once again thanks for the great video.

Deffo would be interested in pre order, I've been looking at this for a while on KZfaq, hope you do get them in 🙏🙏🙏

I love my gen3 65L BZ. The main issue I have is the drain and the controller’s location, but they have addressed that on the new version! I previously owned a GF30 and I’d say the BZ gen4 is by far the best all-in-one system out there at this time.

Nice overview but would love to see it in action. I have the gen 3 version which I am happy with. I agree that I like more hands on and less WiFi/Bluetooth connectivity, but data collection can be important for consistency. Cheers ☮️

Just spotted this while searching for a few other experiences online. I recently got a Gen 4, coming from a G30, and I'd have to say I'm quite unimpressed so far. Straight out of the box the build quality leaves a lot to be desired compared to the G30 and the metal parts quite thin an flimsy. The RAPT portal also leaves a lot be be desired and I don't know what comes before Alpha level test software, but it's in that bracket. On a couple of brews I've found it to be very temperemental as regards holding temp, though I did get it to improve slightly on the second go by having the pump cranked back to a dribble and losing about 10 points efficiency, but it was still varying a lot more than other units I've used. There's apparently a diverter plate to go on the false bottom that fixes this so I wouldn't stock them until that's added. I'm going to attempt to make one to see what happens. Speaking of the false bottom - I have never brewed on any system, homemade or otherwise, that lets as much material into the pump. The second one couldn't even be salvaged as it managed to clog up and block my counterflow chiller completely. Probably needs a large bag in the malt pipe during mash and sparge if one can be found that fits it. Or some other workaround - this seems to be a brewing system that will need a lot of those. On the positive side, the handles are great and it's handy clean the main unit because of the bottom drain hole but unfortunaltely a ruined 20 litre batch of wort is not what you want to be cleaning down through the hole. I haven't completely given up on it yet but the old system will look very tempting the next time I'm brewing.

I plan on getting an all in one system and had been looking at the 65l systems but the ability to extend this as needed with a few extra purchases is a huge selling point for me

Can you connect a Android device directly to the gen 4 using bluetooth...?

Was hoping you will start selling this! Christmas present for myself.

Does anyone use the new Gen4 for distilling. Every single Facebook group or online forum says to stay clear as they don't have voltage control and that even though you can purchase a voltage controller, the screen turns off below 20-30% (which stop the elements). Also, a lot of comments were made about these systems causing excessive smearing due to the elements turning off every time the temperature needs to reduce.

I have done a number of brews on my Gen4 and have experienced a problem with the pump getting blocked so have been unable to extract to the fermenter. Has anyone else had this problem on the Gen4?

What price point would this carry compared to what is already on offer on the site?

Why does using an extension lead cause a fire risk?

When I saw the thumbnail I had hoped you had it for sale. :(

I have a gen 3 but my next purchase will likely be the Speidel once I’ve sold a kidney on eBay….
