Thank you for the review David, concise and to the point as usual. I will probably buy this as it allows for a full volume mash when doing 23 liter batches, as it's what I normally go for. My normal set up is BIAB and this system would allow me to do BIAB for smaller batches and sparge for bigger ones.

So much great and interesting information once again David! I think Grainfather made a smart move in bringing a cheaper system to market and at the same time making it pipeless. Though I am thinking the G40 is where my future is. That extra grain basket size is tempting though....

Excellent video David and very helpful sir. I have discussed both systems with my home brewing friends and the con census of opinion is that all of them would rather have the G40. A few have said they would still have the G30 over the S40. Having said all that if I was new to home brewing I think I would go for the S40 as I think it seems a good starting brewing system. On another note I am drinking your Dunkelweizen recipe beer and it is lovely . I have had some very positive comments from it and my mate Michael Halls who you may be familiar with loved it.

@DavidHeathHomebrew

Cheers, great to hear that yourself and Michael are enjoying the Dunkel :) The S40 is certainly the budget system of Grainfathers range. Its not going to suit everyone but it sure would suit some people. Naturally I am far more excited about the G40 but it is a much more expensive system.

As a very hands on brewer I find the S40 the perfect set up. I like to brew without automation except for temp control and without trying to copy any commercial brews. The one thing that set me back in starting with the S40 was the weight of the grainbasket when doing a 10 gallon brew. Not only is the basket very heavy but also needs to be lifted a fair way up. I solved this by adding an electric cable hoist. I can now lift the basket with ease and lift it clear of the wort which is not possible when resting the basket on the lugs it is fitted with. Now looking at the new SF50 to add to my set up.

Buying this and making 2 modifications. Cam lock the recirculation arm and put a hole in the lid for recirculation to save that secondary element from having to run hot all the way through the mash. That 1000w secondary element is a great feature, the 250w element in a Brewzilla just can't keep a mash in range when brewing in cooler weather. The double skin is cool too, I was wrecking my head looking for a jacket for the S40 but now I see why they didn't manufacture one (it also screws with the electronics if you fit one from what I understand)

Good review David, you seem to have confirmed my feelings about the S40 - simple/basic system but with Grainfather quality and at a price not too much higher than the other budget systems. One question though, you didn't mention much about the lid, I couldn't help notice that there is no opening for the recirculation arm. I was surprised because the only time I ever use the lid on my current All In One is during the mash as it's a big part of reducing the heat loss.

S40, as the one would assume, is ready for 40 l of beer. Guess again. Total volume is 46 liter, if you don't take possible boil off into account. Mashing limit is about 37 liters. Everything over this will leave grain basket under liguid level. Worst of all issues I came across is incapability to achive and hold temperature set. That should be the main advantage of electric all in one system. This one, unfortunately, failed every time. Temperature overshooting was even 12 C (54 F). Increase from 64 C (147 F) to 76 C (169 F) happend in less than 3 minutes. Had to stop it with ice and cold water. Sensor does not "read" the temp correctly, so target exact temp with S40 is a dream. Keep the worth boiling at 100 C (212F)- have to set it up to 102 C and keep it like that. Overall, it gives more headache than it helps. Definitely looking for another system.

Hi David. One thing you didn‘t mention is how well the measured temperature correlates to the temperature within the grain bed. At the end of your video you can see the tiny temperature probe knob on the bottom, so it‘s measuring temperature at the bottom of the kettle right next to where the heating element is mounted to the bottom of the bottom. This is the same set-up as in all the chinese manufactured robobrew/brewzilla/klarstein-type all-in-one brewing systems, and it has been my experience (with a „MaltMaster“) that the temperature within the grain bed can be much cooler than the temperature the probe is measuring, especially if the grain bed gets compacted and flow through less. This can be highly misleading and I would guess could greatly effect the final product as far as residual sweetness vs. dryness is concerned, as you might be effectively mashing at a much lower temperature than you think. Also, since the temperature control “believes“ the temperature is higher, the wort above continues to cool down…giving it a good stir re-equalizes the temperature quickly but you can expect a big temperature drop. The only solution I‘ve found is almost continuous stirring during the mash…what‘s your experience and your solution? Perhaps you could brew again with the s40 and monitor the temperature within the grain bed with a thermometer (without stirring too much) and compare it to the temperature measured by the probe at the bottom?

Hi Josh, most brewing systems are made in China these days, even the very expensive ones. When you have liquid of any kind being heated like this, even if it is being recirculated it is not all going to be the same temperature. The difference is even bigger as you go up in scale. So you can imagine how this is with brewery beer batches. As I mentioned in this video, it is about temperature range, not precise temperature. Certainly I found the temp to be acceptable when I checked it, it was within 1 deg C accurate.

No pump filter ?

Hi David I have a problem with my S40 when boiling the wort I don’t get a boil timer the boiling point where I am is 99 degrees I set the boil to 103 as per the instructions. I did a test setting the s40 to 99 degrees and it switched to the timer but stopped the heating simply displaying warming. Am I missing something here or do you think my s40 is faulty?

It doesnt sound good Andrew. Naturally if you lived at a high elevation then your boiling point could be 99 but I take it that this is not the case. Sounds like you need to speak with where you bought it for a fix.

Does your S40 reaches 100ºC and boils? Mine doesn't and there is only a simmer, not a boil.

Interesting, David. The S40 manual says to “set the temperature to 103°C (218°F)”, which it will never reach and consequently never trigger the timer. If it works at 100ºC why they ask to set it to 103º and time it manually?

103 will ensure a stronger boil essentially.

Hi John, Thank you for your patience. Our tech team have come back to me with the following information; The S40 is a double walled tank. However, the gap between the 2 walls is only about 5~8mm thick so the exterior wall will still be very hot when the water is boiling. I hope this helps!

Yes, though I would have to wonder how that impacts performance. There is no such option in Europe.

I am rather disappointed that they have not used a camlock for the pump arm. I understand that it is a budget system, but it would have only made a $3 price difference. The markings down to 10L would have not cost a penny extra. A 23L batch uses 18-21 litres of water, and a 15L batch quite a bit less. It is almost like if the S40 was an afterthought. Looking at the features that the upcoming Brewzilla 4 will have, I feel that Grainfather have undershot what was possible in that price range, and just put this product out there just to get new brewers into the brand. I also feel that they could have done better with the G40, considering the price point, that is not that far from the Brewtools system, but the features are nowhere close. The only advantage I see is the easier cleaning process as it has fewer parts.

@DavidHeathHomebrew

I would have preferred camlocks, though I do really like the 360 swing meaning that you dont need to add and remove more than once. The markings certainly I would rather had more, though my work arounds are pretty easy really. However do keep in mind that at its price the S40 is a system of compromise compared to the G40. Its all about choices though :) I hope you found my content useful.

What isn’t? And what does that matter, really…most commercial systems are made in China. Unfortunately in the current economic climate if you want a lower price, that’s your best option, if you want to pay 3-4 times the price with the hope of better quality (I can only infer that’s what you are implying) then buy European (a choice I made for my car). It comes down to design, quality control and support, and personally I’ve had no support issues with GF since buying one of their first units.
