Great work as usual David. gen 4 65 brewzillas went live here in Australia as of yesterday. Snapped one up asap. No longer have to mutter jealous obscenities at you while I watch your video's.

Love what you do David. This was a great mini series that I found very informative and helpful. I choose the Brewzilla 65.

Thanks David, well done again. Very nice format on the comparisons and great detail with your info as usual, it’s helped me make up my mind on my new brewing system!

Hi David, thanks for all the great videos. I'll try to give a little bit back. I recently bought the Brewtools B80 Pro and set it up for the first time today and took the measurements for you straight away. First of all, I have to say that a test with 15 litres is not possible. The elements are only safely covered at 20 litres and the sensor is completely covered at 21 litres. Therefore, my test run took place under the following conditions: - 21L volume (Will certainly become a problem, however, if you let the wort circulate through the pipes and the boil off. So in reality more liquid is needed) - Initial water temperature 25°C (elements off until then) - Ambient temperature 27°C - Pump off - Malt basket not installed - PID auto mode - 2x 16A - 230V The time the B80P needed to heat up to 65°C under these circumstances was exactly 08:30 minutes. I hope I could help you with this. Best regards from Germany.

good series of videos David

thank you very much David, it is again well and clearly explained. Very valuable, I'm going to wait until brewzilla gen.4 is available. It's not available in the Netherlands, but I'm willing to come to your store for it..

Great video David. Now that the GF 30Lv3 and the Brewzilla 35L Gen 4 with Brewmonks Stainless Counterflow chiller are the same price, I can't see any reason to not go with the Brewzilla.

Hi, thanks for the videos, liked them a lot as theyy are straight to the facts. one question remained unaswered. How compatible these new brezilla are with Brewfather app? can I brew straight from it, or as like with grainfather I have to move the recepies to their own platform, in this case Rapt, to be able to brew it? thanks again for all your videos, for sure I might never have improved so greatly so fast without them!

In the US, the Brewtools B40 is only about $200 more than the G40, although probably about $300-400 more with a few worthwhile accessories like an extra valve and fittings. I sure like the increased grain bill and batch size flexibilty of the G40 though. If I didn't have the B40, I'd be giving the G40 a strong look. I think it is a real contender now, but wasn't available when I bought my B40. Not that i have any regrets - the B40 is a great system.

Hard to ignore price point of BZ 65 Gen4 and upgradability to increase batch size.

Cheers for the review on all the systems. Just wondering if you have had another chance to test out the G70? Im in the market for a new system and was looking at the G40 or the G70. But watching your review on it 2 years ago I am unsure if those issues have been rectified or not. Any advice would be greatly appreciated.

Thank you for this excellent review! (Liked and subscribed!) Im still undecided as to what system I want to buy. I have been contemplating getting into this hobby for several years now and am a complete beginner. I am looking at either a Grainfather g30v3 or a Brewzilla 35 gen4. I was initially leaning towards grainfather due to their impressive software that appears to make brewing less intimidating, but, the brewzilla is almost half the price here in Canada. What would you recommend for an aspiring brewer?

thanks david for this info video! i am saving upp for a new brewzilla g35 fo it will fit my home and not take upp to musch space. :-)

For me the draw of the BZ gen4 is the low batch volume. When brewing for only one or a few people this makes it much more possible to experiment and try different recipes without being stuck with large quantities going to waste. This along with price point seems to make these systems the obvious entry point. Do you have any experience with close-to-minimum-size batches on the BZ? And how well - if at all - does the RAPT environment integrate with something like Brewfather?

Love the videos but would actually like some opinion, which gives the most satisfying brew day, which was easiest to clean what annoying niggles are there etc etc alongside the cold hard facts! I bought the G40 at the end of last year as I had outgrown my 25l Burco BIAB setup, I enjoy it until it’s time to clean, often find the pump gets clogged with the gunk left in the bottom after you’ve taken out the false bottom. And it’s a heavy bugger, I made a wheeled dolly for it to make it easier to move around my brew shed.

Thanks for another great video! The three systems I’m choosing between are BZ35, g40 and g30. I have to carry my gear up from the basement every time I brew and I have a bad back. How do they compare in terms of 1. carry weight and 2. easy to set up? Cheers!

Have you gotten your hands on Keglands new Duotight Flow Control? If yes - is there a video coming on them? Cheers

Hi David thank you very much for your videos, we are in 2024, which one would you buy? Do you know if Bewzilla will release Gen 5 soon?

I am considering the B80 Pro as i have the space to have a fixed setup and i really like the modular approach and premium components to the product. I have heard a few times that the learning curve for home brewers with B80Pro is steeper than with Grainfather and Brewtools. Could you be more spesific here so i can get an understanding of what to expect? Is the software autmation and simplicity (in case what is not automated), is it the valve setup and how to use (i like the idea of not having a fixed setup and not disconnecting too much during brewing)? anything else i am missing?

Hi David, i'm new to all grain brewing and im having a hard time deciding between the Grainfather g40 and the Brewzilla gen 4 65, which one would you recommend for having a beter experience overall? Thanks so much!

Great comparison, thank you! The g30v3 wasn‘t released back then. Does it change the game for you?

Did you compare the systems for heating from 65 to boil? I have a BZ 35l 3.1 & find it takes ages to come to the boil after sparging.

Thanks a lot! I wonder how fast my g30 heats. Apart from the center pipe brew day speed is the other reason I might switch…

Hi David I've lost your reply to the message sent yesterday about the brewmonk verses the brewzilla gen 4 65 thanks

That's intriguing, how can I run my B40Pro on 320V ? Is that a Norway specific model ?

Which would you recommend the Brewzilla Gen4 35l or the Grainfather S50?

Any time data for the brewzilla gen 4 35L us 110v version?

Does anyone know a EU reseller that deliver to France? I've tried contacting my usual shops but they're not planning on getting any or at least not in the next few months.

A fifty percent price increase for the BZ Gen4 65 over the 35 is considerable. I guess I'll have to carefully consider what batch sizes I want to be able to do and consider whether that jump is worth it.
