Stainless steel pressure fermenter recommendations?

[Phil_G]

Hi all,

I have been brewing for years, for a lot of them using basic kit and my fermenter was glass for the most part. Couple of years ago I got a SS BrewTech 7gal, I really like it has made many great beers. I have however now increased my capacity to 45L ish. As a stop gap I got a 27L Fermzilla when the gen 3.2 came out as I was interested in trying pressure fermentation, and I just split the batches between the two fermenters. I really like the Fermzilla too, it's been a good intro to pressure fermentation. I just wish I had bought the bigger one but there weren't any at the time.

I now I am thinking about getting a ~40L stainless steel pressure fermenter, at the moment the front runner is the BrewBuilt X3 as it looks well put together and reviews have been good. Alternative is the Brewtools F40, although I think that perhaps the 34mm TCs put me off a little and it's also a fair bit more expensive and maybe not so easy to find. SS BrewTech kit seems hard to get in the UK now, I don't think I have seen Spike here at all but I could be wrong.

Any recommendations or things I should keep in mind?
Thanks, Phil

I pressure ferment in Sanke kegs. They're cheap, can be pressurized to +50 psi, fit nicely in a keezer, have built in handles and are built like a brick shithouse. Downsides include the need for a keg cleaner (mine is homemade), they're not very sexy and a full 50 liter keg can way a lot. I stick to US tall 1/4 barrel kegs (7.5 gallon/28 liters). You can get setup @ $200 US per fermenter, 50L or US 1/2 barrel (58 liter).

An adapter goes in the top:

Use a floating pick up:

May not be what your looking for, but it works really good and it's cheap. $1200 is a lot for a single fermenter.

Interesting idea. I do actually have two PET mini pressure fermenters, they are 10L each. I do the odd ferment and serve project with them, often for Xmas. They work pretty well, and go directly in the keezer.

I was thinking that something that I can more easily control the temp etc of would be useful, especially if I also use for fermentation without pressure. Its an idea worth considering though, thanks.

whats the advantage of fermenting under pressure? Vendor gets to sell $$$$ kit?

Spending the $$$$ is optional, I could buy a bigger fermzilla tank for maybe $100 ish.
That aside I have found pressure fermentation useful, made a couple of lagers and the Baltic Porter I just made (which is a lager really) is awesome.

Can you explain why pressurized was useful given the extra cost and complexity of the gear?

 

[Phil_G]

You can ferment a lager at 21C in a week or so and avoid off flavours from the yeast. Normally you would ferment at maybe 12-16C for perhaps 4 weeks to a month. Maybe longer. Is it exactly the same? I am not experienced enough to tell yet.

The Baltic porter I have made is the first time I fermented the same beer half in the pressure fermenter and half the normal way so I will be able to compare these two.

Hmm I think that was the whole USP for Heineken 200 years ago - the development of using chilled storage to make lager (a dutch word meaning to hold in a room or a pound)

It seems that pressure fermenting speeds up the process in the FV say from 10 days say down to 7 days - so for commercial brewers thats profitable.

I think lager is supposed to be fermented cool 12-16C as you say, not room temp - probably defeats the taste objective - but Belgians have their own rules?

It answers the question. There's a lot to be said for those 2/3L PET sparkling soda bottles - they can take 100psi+ - think Ive seen a YT vid of one exploded

Pressure fermentation mimics tall conical fermenters in larger breweries by trapping co2 in solution during fermentation. The co2 causes lower ester production, giving a very "clean" beer. It works really well for lagers, but is not very good ales if your looking for yeast character.

Some people will ferment warmer and under pressure to speed up the process. Ironically, excess co2 slows down fermentation and limits growth, but when the temperature is elevated the yeast go nuts.

One of these?

kegmenter I had the 35lt one bomb proof easy to clean doesn't leak like I've had some plastic fermenters do.

One of these?

They look cool, definitely on the shortlist.

Best value for money, imo. And very easy clean. The simplicity makes it easier to manage and less of a chore than most pressure rated conicals. At home-brew scales, shiny conicals with all the bells and whistles are overkill and do not improve quality of the beer.

One of these?

That's pretty much what I use, only it's 1/4 barrel (28 liter). It's not very shiny, but it works really well.

Been there but I am confused - they mainly sell 'zilla stuff so its a problem to find out what fittings you need

eg where is the recommended spunding valve?
what dip tube assy?
what fitting needed for product transfer?

Any usage instructions link?

I guess any spunding valve would work as they look like standard keg posts on the 4inch TC plate they have in the photos. I can’t look all that well as i only have my phone at the moment.

Below is the link to the Blow Tie spunding valve. You will need to get the associated fittings, but Morebeer sells all that stuff.

what dip tube assy?

This is what you need for a standard Sanke keg, you will need a floating pickup which is the second link. You will need to remove the keg's spear, just look it up on the internets, there are plenty of videos out there.

what fitting needed for product transfer?

Everything I listed is using standard ball lock fittings.

Some assembly is required, but to me, that's the fun part.

 

[robintes]

Cheers bro will follow this up. IMHO these are specialist trade fittings (some may be proprietary) so you have to be sure of a reliable knowledeable source to get the right gear or end up in deep sh8t.

Hi all,

I now I am thinking about getting a ~40L stainless steel pressure fermenter, at the moment the front runner is the BrewBuilt X3 as it looks well put together and reviews have been good. Alternative is the Brewtools F40, although I think that perhaps the 34mm TCs put me off a little and it's also a fair bit more expensive and maybe not so easy to find. SS BrewTech kit seems hard to get in the UK now, I don't think I have seen Spike here at all but I could be wrong.

Any recommendations or things I should keep in mind?
Thanks, Phil

I’ve been eying up a Brewtools F40 myself. They’re spendy for sure but seem like first class quality. I would jump on a Spike CF10 if they came jacketed instead of the coil.

 

[Yontsey]

I didn’t want to start a new thread for a quick question that relates to this. Was looking at the Black Friday sale over at SSBT. Can you do 6-7 gallon batches in the Unitank 2.0 14 gallon? It looks like the jacket only goes half way up the main part of the tank.
