Cask Breather

[Jimmy]

Anyone know of a local, or Canadian source for a cask breather?

No sorry

Some people use propane regulators instead. They are really cheap. Google it maybe and see what you think.

[GuingesRock]

...or just run your normal CO2 setup at 2.2 PSI. Check carbonation tables. That should give you 1.2 vol carbonation at cellar temp = real ale carbonation levels.

I'm not sure of the inner workings of the propane regulator (or the cask breather), but I'm looking for something that can't creep up in pressure. One of the regulators I use now for my CO2 tanks has a pressure creep that I don't trust. I plan on hooking this up to my conical and don't want to chance over-pressurizing it.

[GuingesRock]

I believe the propane regulator works on the same principal as the cask breather, but it might take a bit more googling if you have time. The best explanation I've seen of how the cask breather works is in the cellarmanship book. I quickly googled the propane regulator and it has a similar diaphragm setup.

JImmy are you doing a spundling valve type of thing where you carb in the fermenter?

[Jimmy]

No, just trying to provide positive pressure for when I cold crash in the conical - I want something that doesn't run the risk of over pressurizing it.

[jeffsmith]

For the probable cost of a cask breather, couldn't you just replace the CO2 reg. with a new one?

[JohnnyMac]

Here's the one I have and where I picked it up;

These things are designed to bleed off excess CO2 pressure above 5 psi. So if you've got a creeping regulator, the cask breather will make sure you don't end up over carbonating your beer but anything over 5 psi will be released and you'll end up with an empty tank. You're likely better off with a new regulator or a spunding valve.

It's basically a spundig then.

Jim, I have some parts and pieces if you want to have a look to set up a secondary regulator after your tank.

I didn't plan on using the shitty reg for this - was just making the point that it's something I'm trying to protect against should the regulator I am using decide to fail. I still have a good reg, but I'm not really trusting of any reg at this point.

[GAM]

A sub regulator off your secondary has far less in comming preasure so is less likely to creap.

My secondary is set to carbonate and the subs are for serving.

Like someone mentioned before. People use propane regulators for this for cask ales (there was an article in BYO). The average bbq propane regulator should be set for around 0.4psi.

[NASH]

Is there no prv on your tank? If not you should add one.

Just pressurize the tank headspace to 3 or 4 psi, (or 10 psi, or whatever you like) when you crash cool, then turn the CO2 off. That'll ensure the tank doesn't vacuum.

[Jimmy]

Anyone know where to buy an adjustable PRV/Spunding valve locally, or from a Canadian vendor? I'd like to buy one as a unit, not piece it together.

[NASH]

Try Stellar Industrial for pvrv. If they don't sell them they can likely point you to who does.

[GAM]

I think Chris took one I had but IIRC it was 15lb pre set.

Sandy

[chalmers]

Me Chris? You were kind enough to give me a secondary gauge, but don't believe I have a prv from you.

[GAM]

Ya you. A small brass PRV. It was at the single hop get together. You may have given it back or to someone else.

Jim the secondry offer is still there.

Sandy

[chalmers]

Sorry, I don't remember that, and can't find it in my box of goodies. I might have passed it on, you're right.
