I'm new to kegging so I don't have any previous experience with CO2. I'm not force carbing and don't have room for a 5lb tank so I bought a 20oz tank from the sporting goods store and had it filled. I didn't have a fitting on properly and some CO2 leaked and I could smell it. It had a smell like machine oil or something. I'm not sure if I'm smelling the tank, the CO2 or the regulator. I carefully sprayed some into the air (trying not to suffocate myself) and smelled it again to be sure, and that is what I'm smelling.

Has anyone else experienced this? Should I be worried my beer will end up tasting like this?

Thanks.

Hi

There is indeed such a thing as "food grade" CO2. Some gas comes from really strange places and indeed has weird stuff in it. I've used a lot of bulk CO2 over the years and it can be odd stuff.

Rumor has it that essentially 100% of the CO2 in the St Louis area comes from a certain large brewing establishment in the area. If that's were it comes from it should be food grade (and very beer compatible).

Sounds like the shop filled the tank with COČ that had oil in it. Some PB guns require it.

Or since the tank was new, there might have been some oil in it from the manufacturing process. I would try to stay away from the sporting goods store for co2. Go to a proper gas supplier. If you don't have room for a 5lb tank they do sell small 2.5lb tanks that a gas supplier can fill.

Thanks for the replies. I was told by the LHBS that to their knowledge all CO2 in STL came from the downtown brewery, whether it be welding suppliers like CeeKay or sporting goods stores. I'm kicking myself for not getting a full keg setup with a 5lb tank and going to the beverage supplier to get it filled. I hope I didn't taint the beer. I managed to get some in the keg before I realized it smelled...

Hi

Oil and beer - not a good combination taste wise. It's probably not going to kill you though. If you can't taste it in the beer, you should be fine.

Watch Craig's list for a while. You should be able to score a CO2 tank on the cheap.

I'm wondering if what I'm smelling isn't coming from my regulator. It's a cheap welding regulator from Harbor Freight. I debated pulling the CO2 tank off of the regulator to see if there is any smell from it without the regulator, but I'm not really sure I want to attempt to release CO2 from a little pin valve with 900+lbs of pressure behind it.

You shouldn't be using a welding regulator for draft beer. Welding regulators are high flow, and generally dont regulate down to a low enought pressure for kegginge. Soda Regulators also generally do not work well as the pressures are much higher for soda than for beer.

Yeah, I realized it measure flow rate and not pressure, but I know others that used them successfully and it was cheap. But, alas, you get what you pay for.

BTW, I like your location description. That's great!

CO2 has no odor, one reason it can be a safety issue, so whatever you are smelling is some form of contamination.
