Hi, I just moved to LA from Iowa and want to learn more about the homebrew scene here.

One question is: where do you get CO2? An Airgas store just quoted me about $55 for a 5-lb tank exchange. Is that the best price around?

I brew all-grain and BIAB and make mostly British ales. This winter I made my first lagers (using pressure fermentation) and want to keep going with that.

Cheers, D.
 
Welcome to our forums!

Yowsers!
I paid around $60 for a 20# swap at a local Praxair, last year.

Call around, first.

Locate a local fire extinguisher company. Some will refill your tank, some will swap
Those are a good alternative, too, yes!
I've used those for refills up to a few years ago. Their pricing at the time was better than anywhere else, plus I could wait while they filled it.
When it was due for hydro testing I started swapping at Praxair.
 
Welcome to the group!

Shopping around for co2 is your best idea. Prices are all over the place but every year it has been getting higher.

60 bucks for a twenty pound exchange is where I'm at too in Wisconsin. Co2 is produced here from ethanol production but still expensive.
 
Are you sure it was CO2?
Well... not absolutely. I'm still trying to get this porter keg to kick and had just given up and switched to Glenfiddich. My mood was shifting from jovial to "hold my beer". Sorry, guys. It's been a gnarly week. What I meant to say was, I'm a big fan of British ale. And Mr. Peabody and Sherman.

Thanks to you all for your welcomes and replies. I ended up paying the $55 at Airgas. Since I'm brewing small batches (2.5 gallons) it should last a while. Cheers!
