Turning your Fermonster into a complete closed transfer system for cheap!

[Knightshade]

Would somebody mind posting a pic of the underside of their setup please?

 

[Knightshade]

Well..since I can’t delete the post figured I’d explain WTH I was requesting an underside pic.

I tend to “order” extra parts, mostly o-rings and such. I have a couple extra plastic keg land carbonation caps, which are used in the “molded”version of the fermzilla pressure kit and could not figure why the hell there was talk of drilling +1/2” holes. And I have an extra bulkhead gas post that I at one point considered installing in my anvil kettle lid.

Combined with thinking that the stainless kit used a identical post (just stainless) or bulkhead post and...yeah. Mass confusion ensued, had a HB and I’ve figured it out....I think. But it ain’t pretty...

As long as it holds pressure and can be easily clean, that’s all that matters.

Yeah...it doesn't...at least not overnight it didn't. Assuming it is out of the carbonation cap, so I ordered a liquid bulkhead on amazon yesterday, take 2 works better.

My question is what pressure is required to push out 5 gallons of Star san? it seems to me that the weight of the star san would be a lot in the beginning of the process and fermentation gases don't produce the pressure needed. Am I missing something? I mean sometimes if I put the blow-off tubing too far into a gallon jug the co2 struggles to make bubbles.

I haven't flushed a keg with fermentation CO2 yet but I imagine an active fermentation will have plenty of PSI to push it as long as the tubing isn't way too long. I've had yeast blow the lid off of a bucket I would otherwise need a 'lid wrench' to pry off. Granted, I mostly brew Saisons in the ~1.065 range and fermentation is ROLLIN'...hope this is some sort of help. Can't wait to get this thing set up!

I would imagine your having leaks somewhere if that’s happening, Because fermentation create a lot of pressure. Think about it, if you over prime bottles, you can blow the glass and they’re Rated to 40+ Psi.

that being said, 5 psi or less is all it takes to move liquid out of the keg

 

[cmac62]

Thanks for the responses. I'm definitely interested. I have one fermonster and a couple of the floating diptubes, so all I need are the solid lid and the posts. I'll go back to the first post and see what kind of posts I need.

Is there a way to safely pressure test this setup at home? On one of the youtube video they guy said he tested with 20 psi and was pretty good...

And, actually, I am interested in the 3 gallons version, which if I read well the reviews is made of a bit thinner plastic . I would love to use a fermonster to force carbonate around 14 psi or put a spunding valve on it. If it can really hold 20 psi safely, it would be amazing... Cheap 2L pet bottles can hold over 100 psi, so it does not sound impossible though.

 

[cmac62]

What kind of post do I need to buy? I have a fermzilla, but those posts don't have anything to connect them to the fermonster lid once the holes are drilled. Thanks

So I have gone as high as 15 - 18 during transferring, which is different than holding it for 5-7 days in order to carb it. Since it is not actually rated to be pressurized, for holding pressure i’d error on the side of caution personally—mainly for safety and also to not deal with the rathe of my wife if that thing exploded on isle 10 lol

I bought the fermentassaurus pressure kit for this which is ~$25-30 from morebeer. The posts come with an o-ring and a nut to secure to the fermonster lid.

 

[Elric]

I fermented with my one gallon at 15psi. It held the pressure fine, but it did warp the bottom of the fermenter. Don’t plan to do it again and will also only keep my 3 gallon under low pressure for cold crashes and closed transfers. It does help that I now have a fermzilla all rounder and a repurposed keg both equipped to do pressure ferments so I don't feel the need to do so with the fermonsters.

since I don't need the lid, or the diptube, will this post work? Also, it looks like it has the nut attached. Thanks https://www.amazon.com/gp/slredirec...url=/dp/B085GC53B2/ref=sspa_dk_detail_4?psc=1

That will work but you will need a female threaded barb to attach to the underside in order to attach the floating dip tube To it.

Thanks for the reply, I was going to order a couple of gas in diptubes, that should work also right?

Absolutely, they are all practically the same thing!

 

[Knightshade]

You could also use this....?? I haven't done it yet, so this is a genuine question. If you purchased the above ball lock bulkhead, and utilized below since it comes with a shorter dip tube, then attach the tubing and ball float?

Yes, that would work, as the 3” gas tube is long enough to clear the bulkhead. The standard gas bulkheads are too short to clear.

Thanks, useful info! So I will keep it only under a few psi, for easy cold crashing and to kickoff the transfer.

1) 7 Gallon Fermonster with spigots (makes hydro samples easy)

Like many others have already said, thank you for putting this into a thread! Most of my questions have been answered at this point and I've even developed a few ideas after seeing things I never thought of - nice!

One question, though: what is the best way to grab a hydro sample using the spigot? It seems like this would clog with trub rather easily.

 

[rsquared]

I grab samples all the time from the spigot, for my beers the trub isn't anywhere near high enough to be an issue... Your results may vary depending on style (I don't brew many dry hopped beers).

There are two ways I’ve done it. I’ll prop up the Front of the fermenter at dryhoping so when the hops settle the spigot is still accessible.

I’ve also put a hose clamp at the end of an open ended line and have run it off the floating dip tube

 

[brewneu]

Got my first brew in this setup, also hooked it into the keg full of starsan and it pushed all 5 gallons plus still plenty of co2 bubbling out, only a 3 gallon batch too, thanks! Now just need some volunteers to try spunding at like 10-12 psi...

I've got my first batch in one of these modded fermonsters, now, too.

However, I'm racking to secondary and dry hop in a corny keg, and spunding in that.

 

[brewneu]

That sounds like a really good idea, do you just transfer a couple points before final gravity? Any worry about hops clogging dip tube or grassy off flavors for serving on top of hops for a while?

So, this is my first time EVER dry hopping.

My first time ever doing secondary in corny keg.

My hops will in a mesh tube, I'll leave it dry hopping for five days, then transfer to another corny keg.

I'll be using a floating dip tube for serving.

Make sure every vessel you transfer to is completely purged of oxygen or all you will be doing is diminishing the quality of your beer in every transfer

Yes, I'm aware.

 

[Dgallo]

Yes, I'm aware.

Wasn’t sure since it was your first time every dryhoping. I didn’t know your level of experience, so I just wanted to help if possible. Sorry for the redundancy
