The sight glass is absolutely amazing..

Very useful for sure 🍻🍻🍻

Nice video. I just got my Gen 4.1 from the black Friday sale. Can't wait use it but waiting for a part for me fermenter first. Gets here tomorrow. A couple things to point out; 1) the new clamps note in the instruction manual that they are not to be used for the glass lid. I have mine as loose as possible on the threads and it works on the glass lid just barely but they are really for the kettle extension. I'm going to just use them for storage so that it doesn't fall off, and 2) the sight glass sticker actually had instructions on the back of the sticker backing paper. One last upgrade that is suggested for gen 4.1 is the heat plate that fits in the bottom of the kettle. They have not put it into the kit yet so you have to purchase it separately but may be included in the future.

[@DavidHeathHomebrew]

Thank you and congratulations 🍻🍻🍻 1) Yes, do not clamp the lid with any level of force 2) Yes true. There are further upgrades but these are optional. I have them and have reviewed some of them on the channel 🍻🍻🍻

[@Mgrant8163]

@@DavidHeathHomebrew Thanks. The only thing that I didn't get is the two steps on the mash tube. Apparently, in the US, there was a patent dispute so the US mash tubes only have a stop at the top of the tube to let your gain drain from, you don't get the lower one, just the highest one. I was crossing my fingers but ended up with the US version. I'm thinking about hiring a welder to add them for me.

[@DavidHeathHomebrew]

Oh ok, that is a pity 🍻🍻🍻

[@KegLand]

Top work David. This video is perfect!

[@DavidHeathHomebrew]

Thank you, much appreciated 🍻🍻🍻

[@Shinas1000]

What about software? Can you update 4 to 4.1?

[@craigkinney853]

I'm sorry I noticed some rather concerning safety issues in the installation which would be followed by any manufacturer during assembly. 1. If the earth has been removed then as part of a modification and assembly when the earth is reattached to the cabinet then the earth impedance needs to be tested to ensure it is within specification. 0.04 ohm for instnce from plug to chassis. 2. Ensure the impedance from supply to chassis is greater than 10Mohms as an example. 3. Additionally if there are any grip nuts in place ensure these are in place. The fact the manufacturer has commented that it's a good job (which it appears to be) concerns me as they should understand the specifics of EN61010 and other electrical safety documentation. Add a disclaimer onto the video to this effect.

[@craigkinney853]

The EN61010 is a lab equipment spec but most of the electrical specs follow the same requirements regarding safe working principles

[@DavidHeathHomebrew]

@Shinas1000 The software is updatable on all Gen 4 units via WIFI.

Very useful to any Brewzilla user I'm sure

[@dkuk1281]

Hello David, thank you very much for another priceless video! It would be great to test this solution on G30. Personally, the side glass is the only thing missing from G30 after changing the internal basket and bottom filter.

[@DavidHeathHomebrew]

Thank you. I no longer own a G30 personally, I upgraded to the G40.

[@dkuk1281]

@@DavidHeathHomebrew The G40 is great but apart from the side glass and the improvements made to the G30 there is no significant difference between them (apart from the size of course)

[@DavidHeathHomebrew]

I find it to be a far better upgrade than that. Other highlights are that Its a more heavy duty system with improved heating which is ultra low watt density, improved controller and grain basket plus it has a very good false bottom. In my opinion It is a very good upgrade from a G30 but is in a higher price range too of course.

[@Mr_Daso]

I wonder if you could retrofit the sight glass to a G30 Grainfather. That's a mod/kit I'd love to see!

[@DavidHeathHomebrew]

Could be. I dont have a G30 any longer though to try it. I now have the G40, which has a sight glass.

[@Mr_Daso]

@@DavidHeathHomebrew The sight glass OD is 15mm (from your video description), whereas I just measured the tube on my G30 and it's 12.5mm. It would need some serious modifications on the tabs that hold it in place for it to work I think. Bummer.

[@DavidHeathHomebrew]

Yes, that is a pity then. Perhaps you can find something else suitable.

[@Wind_Ninja_Jubei]

4.1, Still on 3.1.1 and I will until it dies.

[@DavidHeathHomebrew]

Fair enough 🍻🍻🍻

[@Jaytonic3]

I'm curious, regarding the graduation sticker, do you calibrate it with or without the grain basket?

[@DavidHeathHomebrew]

With for sure 🍻🍻🍻

[@devilmaycare2809]

You say in your video that the 25watt pump can be fitted to the 35L gen 4. Do you need to buy anything extra for that upgrade as I've looked at the dimensions and it looks very tight particularly for the centre down pipe.

[@DavidHeathHomebrew]

Sorry but Ive told since making this that it is very tight. I was told previously that it was possible.

[@devilmaycare2809]

I think a 25 watt pump would have to be connected externally as the non kink pipes don't fit at all in any orientation. It might be possible to connect the centre pipe and one other but definitely not all three.

[@DavidHeathHomebrew]

Could be, ive not tried it 🍻🍻🍻

[@DR991_]

Great video! However I didnt understand why whirlpool is not needed on the brewzilla gen4 😮

[@DavidHeathHomebrew]

Thank you. It is because it has a false bottom, which negates the need 🍻🍻🍻

[@chrisnewman861]

I was confused by this too until I realised the term whirlpool is often used to describe a hopstand. The whirlpool spins the wort with the intention of bringing the trub etc into the centre to help with transfer from a tap, therefore the brewzilla false bottom negates the need to whirlpool. However, a hopstand is spinning the wort ( in the past folks have called it whirlpooling) to achieve greater contact time with the hops.

[@DR991_]

@@chrisnewman861 For me whirlpool means once you have finished boiling you swirl the wort during cooling to bring sediment at the bottom center. Hop stands means you stop cooling at some defined temperature for a defined time and then you continue cooling.

[@DavidHeathHomebrew]

Yes, this is correct.

[@chrisnewman861]

@@DR991_ yes agreed this elaborates further on my above comment, cheers.

[@richardhowarth4230]

Great video David, do you think the pump upgrade would work on the grainfather 30?

[@DavidHeathHomebrew]

Many thanks 🍻🍻😅Sure but you would need it to be external. Thats quite a small compartment.

[@richardhowarth4230]

Thank you for your advice

[@DavidHeathHomebrew]

[@stillbald5827]

Would love to have a sight glass on my Anvil

[@DavidHeathHomebrew]

Very handy for sure 🍻🍻🍻

[@josephmolion4345]

Has anyone tried adding this sight glass kit to the Vevor brew system? The setup of the recirculation arm & cam lock assembly looks identical; I'd love to mod my Vevor with this kit!

[@DavidHeathHomebrew]

I havent personally 🍻🍻🍻

[@doodles1977]

For the 35 liter kettle, I do not see the advantage of the more powerful pump. I hardly ever have the valve fully open during mash, and when cooling through a CFC, it is almost fully closed to arrive at the right temperature. I assume if your tapwater is much colder, the extra power might come in handy, but not here in the Netherlands.

[@DavidHeathHomebrew]

It is useful if you need the extra power for your cooling setup or something else. If not then the 6w pump works fine for both systems.

[@Enzo-c5j]

IMO, the liquid tight cordgrip was installed incorrectly. That rubber grommet has no function in that position. 14:03

[@DavidHeathHomebrew]

It is, by design, like that to hold the wiring in place.

[@Enzo-c5j]

​​@@DavidHeathHomebrewWe can see 14:03 that you have such sequence: a) rubber grommet, b) nut, c) screw. It should be like this: a) nut, b) rubber grommet, c) screw. It makes a difference as it should be installed at there by design. 😊

[@DavidHeathHomebrew]

Ok, thanks for pointing that out 🍻🍻🍻

[@PickledAndFermented]

For the sighrglass sticker, do i fill to 20L with nothing inside, or malt pipe in?

[@DavidHeathHomebrew]

Empty 🍻🍻🍻

[@PickledAndFermented]

@@DavidHeathHomebrew thanks sir. Just received my gen 4, and I think I might be lucky to have gotten 4.1, but no instructions exist!

[@DavidHeathHomebrew]

@thirstbuster78 yes, recent units will be 4.1 🍻🍻🍻 Enjoy

[@PickledAndFermented]

@@DavidHeathHomebrew I'm so excited to do my first brew. I used it for an extract kit just to get familiar. Now all I have available is pilsner malt and hallertau hops, planning a smash beer. I hope it works out. No respurces local.. I'll be travelling this winter for grain. Thanks for all you do on this channel to help!

[@DavidHeathHomebrew]

Great, I hope it goes well. Check out my videos for all the info 🍻🍻🍻

[@stevegerla8894]

Would this work on vevor

[@DavidHeathHomebrew]

I am not sure and sadly do not have access to one to try it. If you try it then please let us know 🍻🍻🍻
