Anyone using a stainless steel Conical fermenter

What pressure is that conical rated to take John? Do you transfer under pressure or just use gravity?
Every little helps

Which size did you get and are those prices inc Vat?
Remember: The Nationals are just round the corner - time to get brewing

Are you thinking pushing or fermenting?

I don't believe it's officially rated to anything but I am tempted to put a gas line on and let her blow.

There is a whole different technology in fermenting under pressure like the big boys  and I dabbled with mixed results using Corneys and pressure thumbscrew valves with gauges, it didn't bring enough to the table for me to consider changing.

All those 6 clamps on the top snap down like something engineered from the old USSR and not something you want to get your finger trapped in, I'm sure I'd get 10psi into her to push out into a corny no problem, even though in my case gravity feed is just about achievable.

I'll give it a go at the weekend and let you know

They are all published on his site Will, plus his delivery cost to Ireland of 15 as he uses dpd

I went for the 7 gallon one which has a working volume of 31l more than enough even if I am brewing lively monsters.
I won't be throwing my glassware away anytime soon as picture tells a thousand words just thought it'd be nice to try one out.
All I need now is a drone sub to relay pictures  from the inside

Cool, cheers. I guess I'm most interested in comparing the results to the SS Brewtech conicals. They can handle about 3 or 4 psi before the lid starts to hiss under the pressure. You only need about 1.5 to 2psi to push the beer out in my experience.

I don't know of any homebrew conicals designed for fermentation under pressure. That's another ball game altogether. I've done it with cornies myself too using a bleeder valve. Can't say the beer was much better than batches I've brewed using my normal set up

Will set up a pressure rig and post pics

I put a bung in with a co2 line it went up to 0.5bar consistently before it started to leak through the silicone gasket on the top, enough to push out for transfer but not enough for fermenting under pressure. I guess I could of improved that with keg lube.

Dr Jacoby

Sounds about right. Cornies seem like the only real option for fermenting under pressure at the mo. Cheers for getting back

You were telling me about those at the nationals I think. Would love to give one a go

Just out of interest, what does fermentation under pressure achieve?

Not enough at our level with pilsner for me in any case unless you are doing 2KL

Some info here: http://brulosophy.com/2015/04/27/under-pressure-the-impact-of-higher-psi-fermentations-exbeeriment-results-2/

Bullet points taken from above article:
– The ability to ferment beer at warmer temps without increasing off flavors.
– Overall reduction in yeast ester and fusel production.
– Less vigorous fermentation with reduced krausen, meaning less headspace is necessary.
– Due to the closed fermentation, aroma compounds remain in the beer and aren't blown off.
– CO2 generated from fermentation can be used to naturally carbonate the finished beer.

Might try it though on a split batch, half pressured, half not. Would be very interested in the results
