Grainfather G40 Vs S40 Vs G30 Comparison For Homebrewers

[@alanman5328]

Finally a video today on this topic that actually gives me the information I need. Odd to see some dislikes, must be the jealous competitor channels. Great video as usual!

[@diederikleenarts2796]

Hi David, on the immersion chiller needed to add below boiling whirpool hopping additions. I cool my wort with the counterflow chiller to let's say 80C. Then I stop the pump (and chilling) and add the hops and create a whirlpool. Easy method if you ask me,.

[@FermentationAdventures]

Agreed.. I don’t understand the comment on the need for an immersion chiller.. I can chill to whirlpool with a CFC recirculating back into the kettle. That is a standard part of my process anyway before transferring to the fermenter thru the CFC. I want to reduce hop isomerization before filling the fermenter.

[@DavidHeathHomebrew]

CFC is designed to cool wort in small parts. If you cool the whole thing then its going to take a long long time compared to an immersion chiller. It can be done but its not practical.

[@lakeside477]

I expected more from grainfather to keep up with all the others that we know for that price point, I have a g30 ,a claw hammer 20 gal, spike 20 gal, and brewbuilt 15, not new at this brewing since 1995, Wish it was more exciting. For the money going to try different ones here , Excellent review, and great videos watched every one you have made, Thank you

Great video, thanks for doing this comparison. I tested my US 120V version G30 (with a jacket) using 10L of water and heating from 25C to 65C. The time was 20min 30sec. So 4m 31s longer than your 230V version.

Nice that you included NZ in your content on heating. First glance the S40 looks like a big Robo Brew. I wonder if those little feet on the basket will do the miles!

[@DavidHeathHomebrew]

:) The S40 certainly is more budget but there are pros and cons vs other systems like Brewzilla. I will be doing more comparisons a little further down the line.

[@BillForgette]

I love my G30, and that S40 looks nice as a the new entry point removing what I consider the most intimidating/frustrating pieces from the G30 - the o ring on the bottom plate of the grain basket. Now if I could only get a WIFI controller for my G30 I'd be super happy.

[@DavidHeathHomebrew]

Great to hear Bill. Yes, I think so too. Wifi on the G30 is being developed as an add on. I dont have a date though yet.

So nice! Massive the g40 look compare to g30! Not so storeroom friendly Thanks David!

[@royvaningh6452]

The g40 looks interesting! I am new in this. And i am planning to buy the g30 with the t500 and alembic coper pot to distill whiskey or a clean spirit. My understanding is that only the g30 is capable of doing this since the size in diameter of g40 is bigger then the g30.

[@DavidHeathHomebrew]

Hi Roy, The G40 and G70 are set to have upgrade products later this year that will allow distilling.

[@ShortCircuitedBrewers]

Great info and overview. Thanks David! 👍🍻

[@DavidHeathHomebrew]

Cheers Brian, much appreciated.

[@indiekiduk]

Would have liked to see the inside to learn if the pump inlet has a hop filter but I do understand it’s challenging to filter hops and not grains. The increased diameter should improve sparge efficiency given shallower grain bed.

[@DavidHeathHomebrew]

[@DavidHeathHomebrew]

Thanks Steve. Yes the S40 has the same controller but everything else is new as I understand it. I have a G40 overview and first impressions video coming next, this will give you all you need I believe.

[@andrewadam9544]

your not wrong Steve, identical in the most part

[@eliten0Ob]

Great video David! I have to say, the G40 is a miss for me. One key thing that makes the G30 great, is the ease of cleaning. Removing the overflow pipework, and replacing it with perforation is really not an optimal option. You redirect waterflow from the grain bed to the easiest path, the perforation, impacting sparge efficiency. On top of that, the reinforced channels that prevents the water from just spraying out of the perforations needs massive attention in terms of cleaning. How hard is it to just implement low density heating and the new controller into the G30? Best feature of the new units.

[@aaronhyde5509]

Watch a few of the other videos, you'll notice cleaning isn't too difficult, possibly easier than on the G30. Cleaning the splash guard well may require a brush if you don't address it right after mashing. I've also just watched a couple videos where gravity was overshot on the G40 when brewing G30 recipes, on their first brew, nothing dialed in... I don't think efficiency is a problem! :) Plus, you can stir your mash now, which will be much more efficient in solubilizing starches than a top plate would be (probably why commercial guys use mash mixers and not top plates).

[@DavidHeathHomebrew]

Thank you. I can understand your first reaction here but the reality here is something quite different. Efficiency is very good and more reliable and cleaning has been very easy too. Check out my next video for much more brew information.

[@DavidHeathHomebrew]

Yes, totally agree

[@eliten0Ob]

@@aaronhyde5509 Commercial operations also got multiple vessels, on top of having pumps and monitoring differential pressures. Even though the unit operations are comparable, the tech behind is farther apart. Having brews overshoot with no dialing in is not really sufficient proof; you have a shallower, wider grainbed on this new unit, which is an improvement compared to the G30. How is the efficiency with comparable grain bed depths? I'll love to see Davids follow up video, as this is all very new, and it is easy being an armchair expert. But as a first impression, I'm not super impressed, and I'd love to see it change.

[@DavidHeathHomebrew]

@@eliten0Ob my next video will show you much more than this one does, which is specific to the G40.

[@tonothequick3159]

Great video as usual. I only miss the pricing aspect and what premium means for Grainfather and how it compares with Brewtools, that in my opinion is the system to beat

[@espressomatic]

The S40 is a $100 system - it's literally based on Brewzilla knock-offs. The G40 is their way forward and should be the only system they offer at this size. They need to kill the other system and abandon the S40. Having 4 brew systems that all work differently is a recipe for confusion and disaster.

[@Vormulac1]

As someone who only just bought a G30 and finds the lack of wifi to be somewhat vexing, I hope they'll be offering a controller replacement for that new unit.

[@DavidHeathHomebrew]

A solution is coming :)

[@paulrobertson9439]

Excellent video again, many thanks. I was looking forward to seeing what the new systems would be like and perhaps find an excuse to upgrade my G30 (haha) but personally I think I'm better keeping my G30. There are some very nice features on the G40 but an £1100 40L systems which is less flexible, way too expensive and large for most homebrew sheds is a non starter for me and the S40 is a step backwards in my humble opinion so I'm a bit disappointed with the new systems. Please keep up the great work on this excellent channel . All the best :)

[@DavidHeathHomebrew]

Cheers Paul. I have a detailed video coming on each of the new systems this Sunday. I suggest checking these out for full information first. There are some surprises coming that nobody else has reported on that I am sharing for both. Some of this surprises me and some of it does not.

[@fdk7014]

The S40 is clearly aggressively priced against the Brewzilla 65L however to me it seems the Brewzilla is the better choice. The S40 seems a lot simpler than the BZ. Also, I'm sure Kegland will come out with a new updated version before too long in response to this product. The G40 is interesting but I think they have priced it too high as usual. At €999 it would have been an obvious choice but at €1400 it's starting to hurt. I will stay with my G30 for now since I don't really have space for anything bigger but when the time comes to upgrade I'm sure there will be more compelling options out there.

[@DavidHeathHomebrew]

I guess you could say that about much in the budget sector. The BZ certainly holds its advantages though, at its extra cost. The series 4 Brewzilla is not very far away in AU, Europe will see them early 2022. Its promised to be the biggest levels of upgrade yet. Lets see :)

[@jamesgoacher1606]

Bit short sighted not to have the S40 Controller thingy not WiFi or even Bluetooth. One is tempted to take the drilling machine to my existing G30 Grain Basket of similar vintage to yours but the side exit may lead to grain bed channeling unless they are very small diameter. Very nice Bottom Plates and a welcome reduction in the lift height Mashing->Sparging on the G40 although I would also expect this on to have a greater "Boil Off" rate so different volume calculations. I am looking forward to the Mash Session you will have on Them/It(?). I hope that this time GrainFather supplies it with the correct IEC Cable and connectors in the UK. The previous ones were of the lower current version of the IEC Plug/Socket. Many thanks. :-) Announce ment at last :-).

[@6581punk]

The S40 is a budget system, they're trying to capture the low end of the market where people don't care one bit about wifi and bluetooth.

[@DavidHeathHomebrew]

I think its all a case of price really.

[@timredd]

Thanks David, lots of info for anyone considering a GF brewing system. Been using the G30 since it came out, but it's now retired. I had the time and skills to build my own 45l system based on the Brewtools. I was hoping GF would do something about the leaky lid on their conical that only holds gas pressure at about 1.5 psi. Assuming it's capable of higher pressures, would be nice to convert to pressure fermentation with a replacement lid. But maybe that's not possible.

[@6581punk]

With these systems it seems prudent to wait for brew day videos. Dude Brews and Homebrew Griffo are doing videos which should be up today. But also wait for David's verdict too.

[@DavidHeathHomebrew]

I am going beyond brew day videos with the next content. Not long to wait either :)

[@MrMetalxty]

S40 looks good…. I think the grain basket looks good 😊 but i wonder how well it fares against the brewzilla regarding mash temp accuracy, cant wait to see this in action david!

[@DavidHeathHomebrew]

Cheers Chris. I will cover both of the new units in seperate videos next for full information. Then after this I will look at comparing vs other brands too.

[@duncanbayne3078]

Looks like the S40 has no pump for recirculation or to aid transfer from kettle to fermenter. That means buy a pump or use it at a higher level for gravity transfer and perhaps a winch or pulley to help lift the heavier malt pipe. Its a BIAB and really a different beast to the others. I expect heating been faster if the new ones were insulated, maybe the G30 time without jacket would be a fairer metric.

[@DavidHeathHomebrew]

The S40 has a pump, I will release detailed videos for S40 and G40 this weekend that will give full details on each.

[@RoyNilsen]

The G40 sure looks promising (I'll wait for your next video with more information first ;) ), maybe go that way when upgrading in a few months...

Cheers Roy. I have a G40 overview and first impressions video coming next.

[@rumpelflutsch9327]

Man, i was really looking forward to today. I really thought they would upgrade the G30. Would have ordered instantly. Brew size on average 10-20 liters, a 40 liter system for 1300€ is not really an option. :(

This is very interesting as I'm seriously looking to buy a system. I would be interested to know what the key advantages of the G30 over the S40 are, in simple terms.

[@averellpscheidl761]

Now for something completely different: Where should I put my wort if I only have a 30 liter conical fermenter? Can I please get a 10 liter extension cylinder?

[@DavidHeathHomebrew]

I would suggest splitting into 2 fermenters. Extensions do not exist for fermenters sadly :)

[@A2an]

Grate Video David 👍 What a bout the pump on the G40 ? In my olde G30 I have found the tube going up has lack of attachment or It could be better. My pump startede leaking, and I would have liked a little more power in the pump. Anyway that is just me, I don't uses it so much anymore. My wife brewed a new England IPA on the G30 yesterday while I made the Bourbon Stout on my homemade China Bucket. That was the first brew on the G30 this year.

[@DavidHeathHomebrew]

Many thanks Allan. The G40 pump is certainly powerful enough, it was more powerful than I expected too. The G40 is a big upgrade on the G30 for sure.

[@FLino89]

An upgraded grain basket for the G30 like the one of the G40 would be nice. But I’m not sure that it would work with the sizing of the G30

[@thebackyardbrewer5611]

I think the minimum 5kg grain bill on the S40 is a fail! If you like to brew 1 keg batches of low to mid strength ABV I think you will be chucking a lot of beer away in the process in order to accommodate the 5kg minimum. And no the answer is not to buy an outdated g30 either. If you like to brew lower ABV beers then you will have to pony up for the G40 by the looks of it, or start using lots of mini kegs which is a pain. I threw together a test recipe and to brew a 4.4% blond ale with a 5kg minimum would require 26L into a fermenter. And I know they seem to be aiming at two kegs in their marketing but that makes this system less flexible imo. It seems to me that they have made a conscious decision to favour higher ABV brewing with the S40, is that a fair assessment? That won't suit a lot if brewers then who may think the S40 is just a dumbed down and cheaper version of the G40, because it's looks like that's not the case at all. It's great though if your stick is moderate to high ABV IPAs and you like to brew 1 keg at a time as the S40 will likely suit you very well. Is that a fair assessment?

[@DavidHeathHomebrew]

Sorry for some reason I missed this. Keep in mind that this 5kg minimum grain bill size is just based on what you can mash in an automatic way and get good efficiency. However due to the open nature of the mash there is no reason that I can see that would stop you from adding a smaller amount of grain and then boosting the efficiency with some short periodic stirring.

[@cheshirehomebrew]

Another great video David and looking like the S40 for me. Bit less tech, would it be possible to buy and use a counterflow chiller with the S40? Many thanks from another David 👍🍺

One question, I know the S and G have different pump inlets. Do they both use different or the same pumps? Or can the G move volume faster than the S?

[@MrRaptoos]

Personally, I use platform on wheels for my GF, unfortunately without easy access to this part. As I had about 40 batches on my GF30, I had 2 cases of burning the bottom - both in situations when lautering took more time than usual, yet GF wanted to raise temperature as far as 98-99 celsius. After cleaning this up, during next batch GF had trouble to raise temperature and as learned on Grainfather yt tutorial video I resetted boiler. I know my fault, lessons learned, which is for me is one of the best things about brewing at home. But still, I would feel much more comfortable having these buttons somewhere more accessible.

[@DavidHeathHomebrew]

Yes, I can more than undetstand that Jan. With the G40 you would not have the potential of burning in the first place because it has a low watt density heating system.

I have seen the Grainfather shop price of nearly 1300 euro for the G40. I think that's pretty stout price. Especially when non of the parts can be user replaced like the heating element. The S40 is another Chinese knock out like brewdog,brewzilla,klarstein. The Grainfather spot welded heating elements and 1300 euro price on the G40 are not worth it for me. The Brewtools B40 cost 1700 euro and has better specs , modular parts. So my choice would be a B40 with a immersion chiller. On high priced products i would like to be able to repair parts when needed. On Grainfather this heating pad cannot be replaced. Then it would be a expensive trash-bin after 3 years when there's no warranty anymore. Should the G40 cost under 900 euro, people might change their minds. But at 1300 Euro Brewtools B40 would be my choice.

David, is the S40 High Density or Low Density in regards to the heating elements?

[@DavidHeathHomebrew]

Hi, It has high watt density elements like the G30.

[@DavidHeathHomebrew]

I have much more detailed videos coming on both on Sunday, with plenty nobody else on KZbin has mentioned too.

[@choutoun]

The "budget" is 550€... I'm not sure who will take the S40 over other brands

[@DavidHeathHomebrew]

I see my roll as giving you the information you need to make your own choice. Certainly there are various brands out there :)

Hmmm I can see lots of stuck mashes and sparges coming

[@DavidHeathHomebrew]

Why?
