|
|
I have seen this debate often on forums, and am just sort of trusting kal on all things
I have a milk stout, and would rather just carb than do pure nitro, as its easier for me to get that than make mixes.
My question is what do I need to watch out for if anything if I do things this way. We typically drink an entire keg in a week once we start pouring....
Best
Todd

Kal do you use a nitro tank or a CO2 tank for your beer gas mixture? I purchased a nitro regulator thinking that's what I needed for the beer gas setup and then I found that my LHBS carries beer gas bottles that are set up threaded for CO2 regulators. I'm going to check with the local Airgas place and see if they carry both types but just curious about your setup.

I know there is a lot of bad information on the internet and I read on another forum of a guy who uses a nitro tap, but just runs Co2 through it. He claims he gets the same creamy head as if using the blended gas (Nitro & Co2). Have you heard of this? I don't even know if this is possible. If it is then is the nitro faucet head the reason he gets the same effect as the blended gas? Don't jump all over me everyone I'm just asking as I read this and am curious. It could be completely bogus. If it works it would save some money if it were possible to do it this way......Any thoughts?

I figured as much. Thanks Kal, it's probably bad info that I thought it sounded like.......

You can certainly get the same effect through a stout faucet using pure CO2. The faucet works by forcing beer through a diffuser plate which causes the turbulence to break out CO2 and create those fine bubbles.
The problem with using pure CO2 for your stout faucet is, that over time (in less than a week), your beer will continue to carbonate. Stout faucets typically require 30 psi to pour correctly, and if you had a beer at 30 psi for longer than a few days, your carbonation would sore over 3-4 volumes. Typical beers run through a stout faucet should be at 1.0-1.2 volumes otherwise you run into other problems with the pour. The nitro blend allows you to run the stout faucet keg at 30 psi without forcing more than 1.0-1.5 vol of CO2 into the beer.
Let me know if that makes sense, it's been a while since I took the Micromatic dispense course

Makes sense to me too! Thanks for chiming in! Oh and thanks again for doing an AWESOME job on my control box! I absolutely love that thing!

So that said, my understanding from them is that the tanks are the same. (Mine's a 20# aluminum tank). They simply replaced the CO2 valve with a nitro valve so that I could use a nitro regulator attached to it as the threading is indeed different.

Thanks for the help Kal. I'm going to pick up a new tank after work. Hopefully I'll have my stout on beer gas by Saturday.

Reviving an old thread here... just looking for some insight into carbing on beer gas. At 30 PSI that 30% CO2 blend is going to give you an equivalent 9 PSI CO2 and the resultant volumes CO2 based on your temperature. That being said, can you simply carbonated on pure CO2 at 9 PSI and then purge the headspace and put beer gas on it for serving? Or do nitro beers NEED to be carbonated the entire time on beer gas? Thanks in advance.

Yes. I normally carb mine with CO2 first than switch to Beer gas.

Excellent! Thanks dp! It seemed like I might be wasting good nitrogen if I carbed beers on it as well. I appreciate the reassurance. We are about to brew an Irish Red for St. Patty’s day so I may need to get another nitro faucet to pour that beer on as well. First world problems...

I tried doing that on my last stout. It took forever to get to the correct level of carbonation. Also Beer Gas is much more expensive here locally.
