Brewzilla Gen 4 vs Gen 3 35L & 65L Buyers Guide 

Great to hear, congratulations on the two new systems :)

@@DavidHeathHomebrew Hi David, great video review, thanks. I notice at the 9 minute mark you point out that the Gen 4 false bottom has two pull rings. I have just got a 35L version and it only has one ring, nor does there look like specific machining done to install a second ring on the outer edge. Can you tell me how many rings the final design is supposed to have, please? thanks

@zt7489 I am not 100% sure there, I would suggest reaching out to Kegland on this.

Cheers Brian, I will gradually roll out my findings as time goes on.

Cheers, I have much more planned 🍻🍻🍻

Great, I am glad that you found this useful in making your decision 🍻🍻🍻

Great to hear Davie.

Cheers CH. Much appreciated Bro

Thank you. Yes, I think the 65L is the one to get. Check out my 3 brew experience videos with the 65L GEN 4.

Cheers DTS. I have much more planned 🍻🍻🍻

Thank you. Yes, I cannot wait to brew on these in all different ways 🍻🍻🍻

Awesome. Yes , I would never go back to 3v personally, at home at least anyway 🍻🍻🍻

Thanks Tim , I will be filming a small batch very soon

Cheers Ben, I will be showing all sorts in the future.

Hi Amrith, check out my other GEN 4 videos, I have covered quite a bit there. I am thinking about a GEN 4 tips video for release in the next month or so.

@@DavidHeathHomebrew Have devoured all of them! And yes please! Looking forward to that video - especially how to use the different programmable modes, RAPT etc. On that, I had a question. When we program the different mashes - for eg: say, 30 min at 65c and then another 30 at 75c (please excuse the randomness of this example!), is the system intelligent enough to know that it say, takes, 5 minutes to go from 65 to 75, and hence starts off the heating in minute 25 itself so that at minute 30, the timer starts for 30 minutes of 75 mashing? Then again, that will mean that it was only a 25 minute mash at 65. Or does it start the second 30 minute timer only once it has reached 75? Apologies if the question is long winded and/or slightly naive. Thank you.

Ok great. With mash schedules the timer will only start on each when the temperature is reached. So ramp up time is not included.

@@DavidHeathHomebrew understood. Thank you! Look forward to the future videos

🍻🍻🍻

Cheers, yes hopefully the time will fly by. As Europe waits I will follow with more content as I test and explore.

@@DavidHeathHomebrew That is an excellent idea! Keep up the good work.

🍻🍻🍻

Kegland had their ideas long back too but the tech was not ready back then.

@@DavidHeathHomebrew I can imagine. Any idea in what area the price will land in sweden?

It will be more than the current GEN 3 Brewzilla price but how much more will be down in part to the choice of the retailer. Nothing super extra though really.

@@DavidHeathHomebrew Ok they are usually quite simularly priced across retailers in my expereince. I guess somewhere along the line of the old grainfather at the most then.

Yes but that starts somewhere at least. Are you based in Norway?

Yes, I think a 220-240 model for the US would be the way forward.

Great to hear Darren 🍻🍻🍻

My next brew will be a super small batch 🍻🍻🍻

Cheers Bruce. I will see what I can do there.

​@@DavidHeathHomebrew second that idea, I've struggled a lot with large grain bills, over 8kg and I get a stuck recirculation regardless of the amount of rice hulls I add

For those kinds of grain bills you really should perform a reiterated mash within a 35L system. No need in a 65L system though.

@@DavidHeathHomebrew Kegland gives a max amount of 10.5 kg which is way too much in my opinion. At max fill height there will be around 6 liters of additional dead space around the pipe, resulting in a mash that is too thick to stir. I can't imagine mashing in 10.5kg with a reasonable water to grain ratio in the standard malt pipe.

Just because it will fit, that does not mean it will work well.

I am glad you found this useful 🍻🍻🍻

Thanks Sten. I sure will and much more too.

I brewed the minimum batch size today and filmed it ready for a video coming soon 🍻🍻🍻

@@DavidHeathHomebrew I'm so excited to see this! Thank you for all the effort you put into your channel.

Cheers Gabriel 🍻🍻🍻

Cheers 🍻🍻🍻🍻

Hi Phil, KL have not even considered a GEN 4 yet. This will only happen when there are significant reasons like new innovations. You are probably looking at 5 years as a minimum.

Hi, min batch on Gen 3 is 10L, should be ok with the immersion heater 🍻🍻🍻

Nice idea Leo. I am planning a 5L batch soon :)

Have you considered using a Corny keg (19L) as a fermentation vessel? That has the advantage of being stainless steel, suitable for pressure fermentation or not and dual purpose (ferment + keg). The Fermenter King Junior (20L) is a cheaper alternative, but harder to clean and less durable than a Corny keg.

@@jauld360 Acctually, I hadnt! But I really should! Or maybe a 12l keg, and then transfer the finished product into a 9l keg

@@DavidHeathHomebrew Where do you ferment those? I'd love to be able to "play" and do some science with split batches to test yeast against a control, or test hop expression.

@@leocarlsson3753 I have some 12L Corny kegs for small batches and they are nice. But they cost almost the same as a 19L keg. If you go this route, look at fitting a floating dip tube. Being tall, it takes more time for sediment to settle in a 19L keg than in a bucket, but kegs are good for fermentation. You may be able to store them under the bed too, which is handy if space is an issue.

Cheers James. There will be a stainless steel Fermzilla this year, that will also allow pressure fermentation. I am unsure of temp control will be built in at this point.

Cheers Allan. Yes the Fruit bomb takes a little time to find itself due to all those hoos but when it does be very careful with how many you drink of it!

Hi Leif, Its a very good upgrade. I am using a G30 CFC with mine. Its a very easy conversion to cam locks. I show this in my G30 camlock conversion video. For the CFC you just need one male camlock fitting. When I use the immersion chiller its if there is a hop stand. After this I then switch to CFC for the final transfer. I sometimes show this but not always. Ive not had any issues.

@@DavidHeathHomebrew Great to hear, thanks! Have the camlock fittings for my G30, with good help from your video. Thanks for useful input, I was afraid if clogging or something, but now I've got one thing out of the way, only the money question left 😎😎👍👍👍👍

Ok great, the same camlock fittings work with all Robobrew and Brewzilla units too. So your CFC is ready 🍻🍻🍻

Hi Anders, thank you. Yes the BZ GEN 4 65 will be much cheaper than the G70. I will have a comparison video of BZ GEN 4 vs GF G40 G70 vs Brewtools 40 & 80 Pro. In Norway the GEN 4 units will be about 2000kr more than the 3.1.1. So very good value 🍻🍻🍻

Cheers Parsk. Sounds good to me, thanks for the suggestion. 🍻🍻🍻

@@DavidHeathHomebrew Your content are legendary my friend, and your education has brought me from "total beginner" to maybe "advanced beginner" by now 😀. As of today I have made 35 batches in my life, and maybe 30 of them are your recipes.

Awesome to hear! More coming!

Cheers Jesse. I will be trying out all sorts of different brews with these for sure.

Sounds good to me 🍻🍻🍻 Thanks for your suggestions 😎

As long as it works :)

@@DavidHeathHomebrew still very happy with the purchase saves me a lot of time compared to my 3v set up and I don’t use a top screen on my ss brewtech mash tun, guess it’s just FOMO lol

Great to hear Mitch 🍻🍻🍻

Great to hear Craig. Yes, you can lower the element power via the controller.

Great to hear Brad, cheers 🍻🍻🍻

Hi Robin. I am very careful with the way I conduct production assessments and reviews. I think with such a system it is unrealistic to do a few brews and then a review. Its just not enough. So I prefer as gradual approach. Kegland have a lot of experience and expertise that I find reassuring. At this point I think the main thing will be waiting on firmware updates. However, if you do not live in Australia then by the time this reaches you those matters will already be settled.

@@DavidHeathHomebrew Hi David, I fully understand that a day has only 24h, and you can't test multiple systems to the extend of brewing countless batches and compiling a video with all experiences. Still, your reviews are very valuable, and surely you might have picked up on some things very quickly. Take the overflow pipe from this video as an example. Even if many brewing systems have them, you mention that the gen 4 system is better because it doesn't have one. But would I have gotten this information if you wouldn't have compared two systems? If I'd watch only a gen3 review, maybe I wouldn't be aware that a system without overflow pipe makes some steps easier. It's things like this, which you might pick up easily due to a ton of experience, which other people might not think about enough to mention it. Sure, no one (or at least not nice people) wants to badmouth a product. But there's nothing wrong with constructive criticism, and I'd be happy to get a little extra information, as I myself are only in the very beginning of my brewing journey. Still, I think that your response has just told the most important point about the Brewzilla. You say, maybe it's about waiting for firmware updates. Which tells me, the firmware could maybe use some improvement, but the hardware is all fine. For me that's fantastic news, as firmware can be changed rather easily, but the hardware can't. And finally, I'd like to thank you for your videos. They're not only educational, but for me they're also inspiring. Greetings and best wishes from a Nordic neighbour (the one with the weird language).

Cheers Robin. I have never been happy with overflow pipework, it makes no real sense. Great to see both Grainfather and Kegland moving into the pipeworkless direction. The GF G40 does this well but with a higher pricetag conpated to Kegland. It is however very early days in my Kegland GEN 4 testing. Given some time and I will have the full analysis and answers for you

Thanks Daryll. Release is estimated at around August to September at this point.

I explain all about the differences in wheat types in this video. I hope you do not mind me just linking it, rather than writing all this out. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UIONhpiN0og.html

Cheers Paul, that will be coming in time.

Cheers 🍻🍻🍻

Thank you and cheers 🍻🍻🍻

Thanks Joe. No it will not be the grain basket shown in this video below will fit in both and offers 20% more capacity than the GEN 4 maltpiie. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cT1jMkifqK8.html

Cheers Jason. I do not have a G70 but I do have a G40, which I find much easier to recommend. I will do a comparison and yes the Brewzilla has very similar features and a lower price point. This is not the full story though of course.

@@DavidHeathHomebrew Thank you. I may upgrade to an all-in-one system later this year and I am curious to see a comparison.

🍻🍻🍻

Hey Greg. It seems to me that for most people the supplied pump is enough. The deadspace is very much reduced. I am planning a brewing software profile video for gen 4 35L and 65L that will give all details very soon.

@@DavidHeathHomebrew Fantastic - many thanks!

🍻🍻🍻

Hi Jack, Have you been through the temperature calibration as per the manual?

It's ok thanks I just found your video on pid settings very helpful sorted now thanks for that one David

Ok great, that was going to be my second suggestion. I still suggest temp calibration too , if you have not yet.

Cheers 🍻🍻🍻

Yes.

Thank you 🍻🍻🍻

I guess you can import from England without too much stress?

@@DavidHeathHomebrew Brexit makes it too costly

Yeah that sucks

Yes, I mentioned this in the end section. From the summer to September as a window at present.

You are not alone in this. All part of choice 🍻🍻

17.6lbs is the efficient maximum for GEN 4, this drops to 15.4lbs for GEN 3.

@@DavidHeathHomebrew thank you. Maybe I did something wrong in Brewfather. When I put in your bourbon stout and change the equipment profile to Brewzilla 35l it changes to 19 pounds of grain.

Hmm, did you resize the batch? If not then it should be 14.46lbs

@@DavidHeathHomebrew oh yea I scaled the profile.

That would do it :) I used 19L for that reason 🍻

These are only released in Australia right now.
