Robobrew Brewzilla 3.1 vs Grainfather Full comparison

This is something that I have been asked to do for a long long time now and I happy to say that the Robobrew is now available in Norway and I managed to get hold of one.
This video, for the most part, focuses on facts rather than opinion. I do summerise my opinion at the end also for those that are interested.
Contained in the video is a side by side comparison of the various components, systems and methods that make up both of these all in one brewing systems.
I have done a fair amount of testing with both and reveal data from this testing also within the video.
I do hope you all find this useful, informative and enjoyable.

Much appreciated, thank you :)

[@davevickers5789]

David...I always enjoy your work. I know that your are a longtime GrainFather advocate so I appreciate your openmindedness. Thanks for a great side by side comparison.

[@DavidHeathHomebrew]

Thanks David. Brewing is brewing. Ive used all sorts of equipment over the years. It was great to find a budget system that works this well.

[@matthewkaiser310]

Nice video David! I have watched many of your videos in the past, and they have helped me as a brewer. I purchased a Robobrew based on price point and have been very satisfied. Please consider posting a video of a brew day on your Robobrew. Looking forward to more informative videos and great recipes. Cheers!

[@DavidHeathHomebrew]

Hey, many thanks glad you enjoyed it :) Yes I will :)

Nice review David, I have a grainfather for single brews and bought a Brewzilla 65L for double batches. Both perform their jobs well.

[@DavidHeathHomebrew]

Thanks Tony, great to hear. The 65L isnt available here currently but I will give it a try when it does. Good to hear its working well :)

[@periquito4000]

Great review. The most objective I have seen so far. No wasted time and straight to the point. Excellent. Muy bueno. By the way, could you make a video showing how to mash or brew with the Robobrew? We will appreciate it very much. Thank you

[@DavidHeathHomebrew]

Hi, thank you. The Robobrew is now sold as the Brewzilla. I have many videos on my channel that show its use. Here is a quick start guide:- kzbin.info/www/bejne/fqmve5SrYs11itU

[@samlaw9938]

Brand new to all this and was getting lost, amazing that you picked out the pros and cons as well as educating me on the process, excellent job! Think I’m gonna go for the brewzilla

[@DavidHeathHomebrew]

Great that you found it useful Sam :)

[@sithcass]

G’day David ! I really enjoy your videos and this is a good balanced and honest review. I have recently bought the Robobrew gen 3 and have had 2 reasonably trouble free brews on it so far. I also noticed that you recently joined the Robobrew Brewzilla facebook page, welcome to the darkside :)

[@DavidHeathHomebrew]

Hey :) Great to hear :) Well you know brewing is brewing its all the right side as I see it. I have uses for both, so that works well for me :)

[@launchpad76]

Great video, thanks! I use the Robobrew false bottom under the Grainfather grain basket. There is a small gap between the wall and the false bottom which allows a little bit of hops to collect on the Grainfather filter, but it also does catch a lot of debris. I may try to put an extra silicon gasket around the Robobrew false bottom to check the fit.

[@DavidHeathHomebrew]

Yes, that will work if it becomes an issue. Personally I use the original filter and the false bottom. This covers things nicely.

[@brettarcher7690]

Great presentation. I absolutely love my grainfather controller and being able to Bluetooth it with my phone. This is probably the biggest advantage I can see. The grainfather filter always seems to get blocked, love the idea of a bottom plate filter.

[@DavidHeathHomebrew]

Thanks Brett. I agree on both points :)

[@scotttyson872]

Thanks, David. This certainly helps my imminent purchasing decision.

[@DavidHeathHomebrew]

Great to hear Scot, I just released a larger system comparison video also, if that is of interest :)

[@mikemotta9754]

Thanks for this very informative video. I'm in the process doing some research on buying a brewing system and this was a big help.

[@robertYTB78g]

An excellent video and a great help to me. Thanks for posting.

[@DavidHeathHomebrew]

Thank you Robert, glad you found it useful :)

[@PommyBastard]

Great comparison video. I've used both but own the Robobrew as I got a further discount pre-ordering the first batch of Robo 3s in Australia and couldn't justify spending nearly 4 times the money for the connect controller on the Grainfather. I've found the Grainfather app to still be pretty handy however on my brewdays with the Robo. The first shipment of Robobrew 3s actually came with a silicone ring for the top screen but they didn't include it for long as they found it wasn't necessary but I still use mine out of habit more than anything. Another handy thing to point out on the Robo is the centre point on the bar you use to lift the grain basket out. It's shaped like that in the middle so you can hook it up to a pulley system. I don't do this but I can see how it would be handy for some people. Both are awesome systems and you can't really go wrong with either.

[@DavidHeathHomebrew]

Thank you and Thanks for your insight :)

[@anonexp]

i own a brew monk, and far broke to buy either, why am i even watching this. Probably just addicted to the channel

[@DavidHeathHomebrew]

No worries, as long as you are happy with it :) Great beer can be made without much outlay :)

[@anonexp]

The truth had been told. After watching the whole video i must admit my trusty monk is a pretty big bang for the buck actually. Thanks for the vid David, one day i might buy a g30. Cheers

[@DavidHeathHomebrew]

There are more up to date systems out there already compared to the G30. An upgrade has to be close.

[@canilsenmusic]

Thank you for the well-made comparison video! I've had the opportunity to brew on both RoboBrew and Grainfather so I can share my opinion as well: My conclusion seems to be the same as yours: The major difference is the controller unit, and the difference is huge. With that said, the price difference is so big that certain quality improvements must be expected from the Grainfather. Personally I prefer my brewing session to be as manually controlled as possible, so RoboBrew fits my needs perfectly. To me homebrewing is a recreational pursuit, where the small things like checking temperature and adjusting flow rates etc. are something I really enjoy. The RoboBrew controller unit can be programmed with up to 6 steps (temperature+time), but personally I quickly switched to manual mode and never looked back. The placement of the controller on RoboBrew, as you mentioned, is quite annoying compared to Grainfather. You will actually have to lay flat on the ground to be able to read it properly if it's placed on the floor. I guess a little bit of exercise during the session doesn't hurt... One difference I think you forgot to mention is the stainless steel ball valve tap on the RoboBrew. This has many uses in my opinion, and Grainfather for some reason doesn't have this. I have yet to find another compact brewery that doesn't include a tap. Another important difference is the placement of the temperature probe. Grainfather has done a smart thing by placing it a bit higher up on the side, while RoboBrew (and pretty much every other economy-class brewery) has it mounted to the bottom. Having it further up removes the possibility of the probe getting insulated with debris, and guarantees a correct reading through the whole process. All in all I was expecting the RoboBrew to feel a lot more cheap compared to Grainfather. It does not, meaning the value for money is very good.

[@DavidHeathHomebrew]

Hi Carsten, Thank you much appreciated. Good to see our findings are aligned! Its not that I forgot the tap more than I showed it in video footage but didnt mention in verbally. I did have a comment on it in my first script but decided to leave it out to keep the flow of the video going. I had quite a tough job with footage as my gimbal kept failing!

[@canilsenmusic]

@@DavidHeathHomebrew All good, the video would need to be 2 hours long to cover all the details. Like the height of the sparge arm, where Grainfather's low arm makes it really hard to remove the glass lid without detaching the arm. I'm looking forward to see all the improvement ideas that videos like this will trigger from the community!

[@DavidHeathHomebrew]

Haha very true :)

[@timothy4]

Hi David. Thanks for the superb videos, watching them has been very enjoyable and added positively to my homebrewing thinking in quite a big way. I held back on buying a GF and think I was a bit uncomfortable with the price and felt I could not justify it based on my needs. The Robobrew 3 however is a no-brainer for me and I now have a unit on order. I never really felt that I needed a Connect Controller and are more inclined to do things manually so the difference in price point which centres quite a bit around the Connect Controller is probably a waste of money for me personally. Your video has assured me of the quality of the Robobrew 3 which perhaps was not quite there with the version 2 and dissuaded me from purchasing the version 2 unit.

[@DavidHeathHomebrew]

[@johnintanzania]

Thanks David. Great comparison video.

[@DavidHeathHomebrew]

Many thanks John, great to hear :)

[@johnintanzania]

Out of curiosity, have you had a chance to look at the Klarstein line of all in one brewing systems? They have a rather large range and I was curious to find out how they stack up to Grainfather or Robobrew.

[@DavidHeathHomebrew]

I have tested earlier versions that had the same issues as the Bulldog but nothing current yet. These are sold under various brands with small differences like Ace and Brewster Beacon, Brewcat and so on. They could have moved on. The earlier versions of the Robobrew were much the same but that has improved greatly, perhaps some versions of this have improved also. I've seen people say the Brewster Beacon is a good version. I hope to try it at some point.

[@JnourseNZ]

Fantastic review!! Thank you.

[@DavidHeathHomebrew]

Many thanks, glad you enjoyed it Jonathan:)

[@marvinwright3963]

Good comparison thanks Dave. I like the easy of using my phone and cfc chiller the Grainfather offers. It also seems that if the pump fails, the GF would be easier to replace.

[@DavidHeathHomebrew]

Thank you Hasse, great to hear this feedback :)

[@scottn1au]

Great video. I appreciate the effort you put into this. I will be buying the Robobrew due to cost factor, I wish it had a better controller with the ability to link to a phone app. I believe you can use the chilling coil on the Robobrew as a CFC also.

[@DavidHeathHomebrew]

Great to hear thank you. You can use the immersion chiller supplied in a couple of different ways and at extra cost there is a full CFC also...well worth getting!

[@BennyBestt]

Great review David, I ended up getting the 65 litre Robobrew/ Brewzilla, I've brewed over 50 brews, no issues so far. brew day with no chill method is 4 hours start to finish, cold water in, hot wort into cube. Cheers,

[@kenfowler5407]

Hi David, another great video! I agree with your comments about both systems so I have decided to buy the camlock upgrade, the valve and the false bottom from Kegland and fit them to my Grainfather. Now I know the lid is interchangeable that will be on my list too! I measured the false bottom and it should fit - if not I am waiting for the Lauter helix to become available from the same supplier. I am fitting the Robobrew valve in place of the product outlet because I hate lifting the Grainfather up and tipping it to get water out plus if ever the pump fails I will be able to quickly disconnect it and drain safely! This video was so timely! Hopefully version 3 of the Grainfather will take this on board! Cheers

[@DavidHeathHomebrew]

Thanks Ken :) If you use the kegland false bottom then you will also need the grain basket from them. I am yet to try this though but I will soon.

[@kenfowler5407]

David Heath is this because of the added height?

[@DavidHeathHomebrew]

Ken FOWLER Yes, the RB grain basket is a little shorter for this reason. I will best testing things like this and how they work soon

[@kenfowler5407]

David Heath I’m just going to use it for small batches until the Lauter helix is back in stock ( it’s good Kegland in in Australia ;) )

Thanks. Its not so much an issue. There is just not a ready to go solution. People have cut down replacement pipework with good success though.

[@ottothecocker]

[@DavidHeathHomebrew]

[@smouskat7233]

Nice video, I have a G30 and I use a false bottom and a hexcoil beneath it. Works great I bought them from a firm in Italy

[@DavidHeathHomebrew]

Great, it certainly is a great way to go.

[@davidblunn7143]

Hi David, in regard to the lack of small batch capability on the RoboBrew, Kegland sell the two bits of pipework as spare parts ($10 each in Australia). These can be cut down to a shorter length without damaging the threaded section on the bottom pipe or the clip on the upper pipe. The shortened pipework is then used like the one sold for the Grain father. I have the 35L Robo and the only criticism I have is that the controller starts counting the step time as soon as the previous step finishes rather than when the new step temperature is reached.

[@DavidHeathHomebrew]

Thanks for the insight David, I was thinking along these lines myself :) Yes that is true on the controller but easy to predict after some use.

[@theatticdesign]

That was great! Thanks so much!

[@DavidHeathHomebrew]

Many thanks Ben :)

[@kanehancock]

Thanks for your very informative video David! I have recently ordered a grainfather(still waiting for it as the post is a bit slow at the moment) then I saw this video. I must admit initially i doubted my purchase and wished i had bought a brewzilla instead. On reflection though I believe i made the right choice for the following reasons: - The bluetooth controller(even though there are outstanding issues) - Cfc - Positioning of the controller - A tried and true product in the market - Being close to one of the head offices gives me confidence of good support😀 - Cheap and easy options to give upgrades - I still don't trust the robobrew electronics.... At the end of the day I look forward to many years of homebrew on my gf system! Thanks again David!

[@DavidHeathHomebrew]

Both of these systems are good. There are just pros and cons in comparing them. There is quite a price difference, so thats the thing to consider vs the extras on the GF. The electrics are very similar on both of these if you open them up.

[@kanehancock]

@@DavidHeathHomebrew Very true there are pros v cons. Interesting regarding the electronics! Overall I'm still glad I went for the gf even with the extra cost. As you said you need to make the decision for yourself and what you want out of the system. Cheers mate!

[@miguel_fueguito]

Love your videos! Are the chillers included in both systems?

[@DavidHeathHomebrew]

Thank you :) Yes, with both :)

[@gowerski]

Although its not recommended by the manufacturer, the counterflow chiller in the GF can be used to recirculate back into the main vessel, cooling it down quickly for post boil hop additions

[@DavidHeathHomebrew]

Sure it can but its slow compared to a cooling spiral.

[@lordsigurdthorolf1202]

Thank You from Phoenix Arizona ;

[@DavidHeathHomebrew]

🍻🍻🍻Much appreciated 🍻🍻🍻

[@ModernGameChangers]

I went through many months deciding between new electric systems. I considered both of these but in the end, I chose neither. I ended up choosing the Clawhammer electric system. It seemed to be the best of all worlds. It's a complete BIAB system that I couldn't be happier with and in my opinion it gave me more options, and also the price what excellent for all the equipment they include. Its an option I would recommend for anyone looking into an all-electric system.

[@DavidHeathHomebrew]

Clawhammer is not available here, glad to hear that you are enjoying it though :)

[@krogilds]

Hi David, great review, thanks. What is the minimum brew size you can brew on the GF? And what are the purpose of the silicon rings on the GF? Are they not needed?

[@DavidHeathHomebrew]

Hi :) You can go as low as 10L with the extra pipework or 15L as standard.

[@JoshOB21]

This video just made me so happy that I chose to get the robobrew instead of paying more for the grain father. My only knock is the top screen, for me it's given a false illusion that the grain bed is covered with water while mashing and recirculating and I've lost significant efficiency because of this. When I took it out during the mash the top of the grain bed was above the water level, even though the screen (when in) was submerged.

[@DavidHeathHomebrew]

Great to hear. In regards to the top screen positioning is important to avoid the point you made. Push it down flush to the grain and then raise it a slight amount.

[@JoshOB21]

@@DavidHeathHomebrew yeah mate I just dont use it now.. it's not essential and gets in the way because I like to stir every now and then, especially if doing a step mash or any time I raise the temp during mash in/out

[@DavidHeathHomebrew]

Yes sure no worries there.

[@richiejenkins2000]

Well done David. Thought I was dead set on the Grainfather , but you have given us reasons to give the Robobrew another look. Simple things like the lid and unit handles, the notched tube handle and the cam lock... makes you wonder why they are missing from something as high end as the Grainfather is. When adding a cam lock to the Grainfather- do you then lose the safety valve feature? I am giving it all another thought, but I must say it’s the higher position of that controller and its incredible features that still have me leaning towards the Grainfather. The ready to go counter flow chiller is another big plus. Thanks again David. Happy Brewing.

[@DavidHeathHomebrew]

Thanks Richie. The choice between these is full of pros and cons! I guess you could do a camlock conversion and keep the safety feature but you would be doing it differently to others. You can close off the valve instead during the boil to make sure there are no accidents though. Yes the controller and CFC are really a large parts of the process and should not be put aside if the cost is a non issue for you.

[@ThatInfidel1]

David, Great video. I have on occasion felt you were a bit biased toward the Grainfather line of products, and I am happy to feel wrong about my assumptions now. There are a few items that may be of interest to you about the Robobrew versions of old. (For reference I own 2 robos and a GF, although I don't have the BT controller version) The pipework used to have the same system as the grainfather, as well as the malt screens having silicon. Even the 3.0 robobrew I received right before the 3.1 came out (grrrr) had silicon for the top screen, but not the bottom. Even older models had silicon everywhere. The camlock addition was new to the 3.0 line, 2.0 and older were identical to the Grainfather in that regard. While the pump is indeed fully manual, the elements can be left fully "on" and the system will control them as it needs to, I think the switches are just there as a safety measure for the most part (I could be wrong about the reasons I dunno...) No argument at all regarding the position of the Robo controller... they really should consider a more accessible controller for us floor brewers. I use my Robo on a milk crate and that's still a bit too low to save my back. The extra screen at the bottom of the malt pipe is new to the 3.0 line, and some users have stated it's more trouble than it's worth. Personally I couldn't say, I haven't used it. Last thing, you mentioned wanting a false bottom, consider using the False bottom from your Robo in the GF, it'll fit. You could also use the Robo's malt pipe since I believe the only reason it's smaller is to accommodate the false bottom. If you prefer the GF pipework and screen I suspect you could probably interchange those as well.. i haven't tried but it all looks to fit together nicely enough.. ok that's all I have.. Again, fantastic vid!

[@DavidHeathHomebrew]

🍻🍻😎 Much appreciated 🍻🍻😎

[@bigdavylove]

Great video, really helpful. I also do small batches.. can you explain why the BrewZilla couldn't handle them? You mentioned small pipework, but I was struggling to work out what that meant in practise. (What is the smallest batch size either could handle?

[@DavidHeathHomebrew]

Thank you. You can do 15L batches in both by standard and in some cases lower. Gf have a “small batch pipework” product that allows 10L. Brewzilla doesnt have this but some users have bought the standard pipework and cut it in half to mimic this. Cheaper also :)

[@greybeard27]

Good review! I've been using a Grainfather with the old controller for a few years, never bothered with the upgrade to the new controller, as running it fully manual isn't exactly hard work. In this respect I don't see the Robobrew controller as much of an issue in use. What does appeal is the price, compared to the Grainfather I could buy 2 Robobrew units and easily do a parallel double brew day with an IPA in one and a Scotch Ale in the other, for example. Or double up on one recipe I have that has an 80% beer tax on it (the one my mates love and keep coming around to drink).

[@DavidHeathHomebrew]

Fair play. If you dont need it then not point paying for it. For sure the Robobrew is more value on this basis but I would also grab a cfc :)

[@Peter-zr8kq]

Tremendous review. Thank you! I will get less expensive one and it’s on sale. How do you sparge?

[@grahamthompson990]

Thank you David an excellent presentation. I am looking to get into mash brewing and I like the idea that the Grainfather will accommodate smaller batch brewing. In your opinion however do you think that the Robobrew could easily be modified to accommodate smaller batches also.

[@DavidHeathHomebrew]

Thanks Graham. Yes indeed it can. The standard pipework is fine for 15L batches and you can buy a second pipework very cheaply, which some people have cut down to accommodate smaller batches. I am yet to try this but I cannot see why it would not work.

Thanks for a great comparison, David. I currently own the Grainfather but have been looking at the Robobrew since the GF Community app fiasco. I'm curious whether you still prefer the Connect controller since they rolled out the new app? Personally I've reverted to using my GF manually as I did with the original controller. I'm also a fan of small batch brewing and low gravity session beers. Whats the smallest grain bill you've been able to do with the Robo? Thanks!

[@DavidHeathHomebrew]

I stopped using the GF Connect with the app early this year. This was because the recipe creator was very inaccurate and really I do not need a handheld process. I tried the new app and had multiple problems each brew. The recipe creator is just as inaccurate as ever and now the ui is far worse. So like you I am back to manual mode and use Brewfather for calculations. Works just great :) I also own a Robobrew. They both do the same job.

[@blairmacleod4564]

This comparison was quite nice. I was wondering if you knew about future generations coming out on either for the grainfather or robobrew 3.1.1? I know the g70 came out and the 65l brewzilla were released, but I'm looking into the smaller version between the two and do not want to purchase them if a new version is going to be released soon.

[@DavidHeathHomebrew]

Thanks Blair, no news on either at this point. I have a larger system comparison guide coming very soon.

[@MultiSigil]

Thanks for this, do you know if the robobrew false bottom fits the GF? Not a massive fan of the small filter on the GF when using hop pellets as I find it clogs up the filter even after wirlpooling.

[@DavidHeathHomebrew]

I intend to trail a mix of components from both soon :)

[@rickspooner]

Great video. I was wondering if the small batch pipework from the Grainfather fits on the Robobrew? Also, I find the false bottom doesn’t fit well and there’s a gap around it that let crap go through. Is there a way to improve that? Maybe by installing a silicone gasket from the grain basket?

[@DavidHeathHomebrew]

Thank you. I will be trying various parts from each and seeing what works and what doesnt. No sooner did I film this video and a friend borrowed the Robobrew for the weekend!

[@rickspooner]

David Heath Hey David, just saw your new video about the false bottom, do you have a gap around it that let stuff go through? Also, did you have a chance to test the small batch pipework on the robobrew basket?

[@MRGIT999]

Is there any issues with programming the Robobrew when the unit is placed on the floor which I believe most users do so they can easily remove mash basket

[@DavidHeathHomebrew]

Just the comfort side really but its not like it takes long.

[@leftiesrule]

Great video! Two questions for you. In your temperature test how were you measuring the actual temperature? Do you have any idea how well suited the Robobrew is for smaller batches, say around 2.5-3 gallons?

[@DavidHeathHomebrew]

As I understand it 4 gallons is the min with the supplied pipework. I have heard from people who have bought spare pipework and have cut it in half to work with lower volumes. I have not tried it myself though.

[@leftiesrule]

@@DavidHeathHomebrew thanks for the reply. For the actual temperature are you measuring it by sticking a probe in various places in and around the mash or measuring the temp of the liquid going on the top of the mash. The reason I ask is I currently have a recirculating eBIAB setup and find the thermocouple at the bottom of the kettle to be a few degrees off from a probe inserted to the top of the mash. While I haven't used a grainfather or robobrew I imagine this would happen in most systems like this so wanted to get your strategy on measuring/handling the temperature stratification.

[@DavidHeathHomebrew]

Ops I forgot to answer that. Sorry, long day. My testing method is to use a calibrated high accuracy temp probe in the heart of the water whilst there is recirculation. This is a brewing trade method and the results are based on 3 tests that are then calculated and the value is a mean average of the 3 results.

[@elbwood]

Dear David, thank's a lot for Your wonderful videos and well thought out informations! I decided to go for a brewzilla 35l V3.1 and just ordered one. Since You have both systems: Did You ever try if the the micro pipework of the Grainfather fits the brewzilla as well? I would love to be able to do small batches and gain a little more flexibility.

[@DavidHeathHomebrew]

Thanks Frank. Sadly not. There is a cheaper work around though. Buy an extra normal pipework from Kegland. Cut this down by about 40-50%. You now have small batch pipework. I am yet to try this.

[@elbwood]

Need, no, not for all. It is for protection and fit. Fit varies. Give it a try :)

[@Jeff_MT09]

Hi David. Thanks for another great video - I’ll be looking forward to your future brews using these systems. I live in Australia and bought a GF connect about a year ago for $1150AUD. At the time there was a lot of quality control issues with the RB - and legal issues over here between companies making and marketing them. That seems to have worked out now and the RB has been through a lot of R&D since then and appears to be a much better product now. Two issues I still have with the RB is that you have to supply hoses and fittings for the chiller, and, the RB chiller is still made of stainless steel - I understood copper is a better heat exchange material than stainless steel. Maybe you can show how to connect the RB chiller pipes, and, do a comparison between chilling times! :-) Thanks again. Cheers.

[@DavidHeathHomebrew]

Thanks Jeff. Yes things have certainly evolved in this time. The problem with copper is many are alarmed by the potential health issues. This has caused a shift in the market with SS being introduced by many suppliers. It is not as good but it pleases many. Yes I agree that the RB should at least come with chiller fittings.

[@Jeff_MT09]

David Heath Thanks David for your response. Fair enough people are concerned about potential health issues with copper - I understand. I’m sure if I had a RB I could rig up some hoses, but agree, they really should have some type of fitting attached. Keep on brewing and keep those videos coming - I really get excited each time I see a new David Heath video. Cheers. Jeff

[@DavidHeathHomebrew]

They actually have a CFC that goes straight on, strange really!

[@deejaydoubleyoo]

Good side by side comparison, although I don't recall you mentioning the valve on the bottom of the Robobrew vs not having one on the Grainfather. I use it to gravity fill my fermenter which I find handy but then again with the CFC on the Grainfather that wouldn't be necessary.

[@DavidHeathHomebrew]

Many thanks. Yes the tap is a useful addition, I thought that I did mention it? Hmm

[@deejaydoubleyoo]

@@DavidHeathHomebrew There's a good chance you did and I probably missed it.

[@henry1237]

Hi David - thanks for another excellent video. Do you find the lack of PID in the Brewzilla controller causes any issues with overshooting mash temperatures or other problems with temperature control? Would it be worth the trouble to add a PID-enabled controller to the Brewzilla? Grateful for your thoughts as always!

[@DavidHeathHomebrew]

Thanks Henry, much appreciated :) I've not had any over shooting at all with the 35L or 65L Brewzilla units. So it doesn't seem worth changing to me.

Hi David, Thanks for the video...appreciate the review..one of the things I do dislike about the GF is the screw on fittings over the camlocks from robo. Any chance you know a good place to buy the parts to convert the GF? I’m a US guy and it seems like over here fittings are NPT whereas I understand the GF fittings are BSP fittings so I’m having trouble here finding this conversion to do it properly. Thanks in advance.

[@DavidHeathHomebrew]

Hi, Ive not found anywhere that sells all parts as a kit sadly. I do intend to do a video guide showing the parts and include a how to.

[@EngineeringDisaster]

David Heath can’t wait for this video 👍🏻. Definitely something I think should have been Done on the GF from the start.

[@jimmythekidd78]

Great comparison of features. I've been looking at the Brew Monk and also the Robobrew so this was really interesting to see the Robobrew compared to one of the 'Big Guns'. One thing I've wondered is if you could just use a BIAB bag in the Robobrew so have the bag open at the top and the wort recirculating through the top? It does seem a bit strange (at least to me) that the grain baskets with these all in ones only have mesh bottoms as opposed to having mesh sides and bottoms which you do see on some of the high end US systems like the Clawhammer electric kettles. There is probably a scientific/use reason for that though, maybe the re-circulation pump would just clog all of the time. Thanks for the video.

[@DavidHeathHomebrew]

Thanks James. Actually I wondered exactly this when I first started using all in one systems. I did some testing and got very similar results back from using a bag and a grainbasket. The Robobrew (now really the Brewzilla) also has a sister product called the Digiboil, that is a uncirculated BIAB brewer. Ive used that a fair bit and it also works well for what it is. I used it in this video:- kzbin.info/www/bejne/oIjbkHWeZ891orM

[@jimmythekidd78]

@@DavidHeathHomebrew Glad I wasn't the only person curious about this and interesting that you got pretty much the same results from the experiment.

Thanks for a very good video. I have today the Bulldog brewer 30 L (same as Cobra) - how would you rate the quality of Robo Brew and Grainfather vs that one - I'm considering to buy a new system.

[@DavidHeathHomebrew]

Thanks Bjorn. I would put it below both of them in terms of quality and reliability. Though right now (and for some time) the GF software is very buggy still. I have a more recent guide series here:- kzbin.info/aero/PLeY07JqsrXM8qdQcqQnMGB2T5h9PLpt_Z

Hi! if heating elements were to break, how could they be replaced?

[@DavidHeathHomebrew]

Thats going to be a problem as heating elements are welded on all systems that I have seen. Its unusual for them to fail without being abused or used in a wrong way.

[@danielerusso7451]

Thanks David for this video, about mash thickness, brewfather formula is grain kilos x 2,7 +3,5 for brewzilla I see you use grain kilos x 3 + 6,75, what is the reason for this difference?

Could it be that you are looking at a profile for the 65L Brewzilla not the 35L?

[@simonharrison7406]

Great video! I am still on the fence as to which to system to buy but this helped a bit. I do like the controller and counterflow chiller on the grainfather though i am not certain it is worth the extra $. Having done 6 brews or so using the manual stovetop method which was a pain and not very accurate i think i could go with either of these for my first all in one electric system

Since this video was made Brewzillas have been upgraded further. Better controller and improved heating elements that eliminates bottom burning.

[@davebirke9304]

Thanks for another informative video. I have a couple of questions regarding the general brew time for these systems. I currently brew 12L BIAB (14.5l pre boil)on a gas stove and takes around 3.5 - 4 hours. With these systems if the mash water had been set on the delayed timer, from start of mash to end of clean up what would be the average brew day for a 19L batch ? Do you feel much time would be saved by doing full volume/no sparge for a 12L - 15L brew using extra grain to adjust for lower efficiency? Or do you feel the systems wouldn't work well for this method? Thanks

[@DavidHeathHomebrew]

Hi Dave, I don’t think you will save much time compared. The key advantage of all in one systems is greater efficiency, ease of temp control, convenience and flexibility of volume. You can also brew anywhere with a water supply and power.

[@davebirke9304]

@@DavidHeathHomebrew hi, thanks for your response. It's definitely the ease of taking the brewing to the man cave that will please the Mrs..My main concern is the possible increase on the time. I have read various forums suggesting grain father brew days between 4-7 hours. On a UK volt system do you think 4 hours would be achievable from start of mash to clean up with a 19l batch? Thanks

Different people take different time. I can easily do a 4 hour turn around with a 60 min boil. I clean up as I go.
