I found someone looking to unload a bunch of 7 gal carboys fo $25 each. So if they will work I may jump on it.

I have four 7.5 gal carboys.. they work great. I have done 5 gallon batches in them.. but why stop there? Make 7 gallons of beer instead.
For the last 20 years I have never seen or had the ability to order a 7.5 gallon carboy. They are probably 6.5 gallon or they are older than me.

I just stumbled across this thread because I found someone selling 7.5 gallon carboys for $15.
Just to confirm, these would be good primary fermenters, correct?
They are fine for primaries because the CO2 produced blankets your beer and protects it from oxygenation. Once moved to secondary little fermentation occurs allowing oxygenation to occur if too much headspace is present.

I've seen 7, 7.5, and there's someone selling a 10 gallon carboy on San Diego craigslist right now. They're probably older than you, and I wouldn't doubt it. Carboys last forever if they're taken care of.
I appreciate the reply.
I've yet to brew, but I'm slowly collecting everything I need. I already have a plastic bucket and three 5-gallon carboys, but I cannot pass these up for $15 a piece.
I spotted those on Craigslist, too! :rockin:
yeah, i just saw them on craigslist and came to the forum to see what the deal was.
so they are 6.5 gallon? what is an acid carboy?

Given the headspace, would it be acceptable to leave a beer in the primary for a longer time without racking to secondary at all, or would the CO2 exit the carboy after a week or so, thus allowing oxygen in?
I have no problem moving the beer to a 5 gallon carboy, but I've been reading recently about the success people have by leaving their beers in the primary for a longer time and skipping the secondary altogether.
Could anyone answer the question below? I see that I could indeed primary in the 7.5 gallon carboy, but essentially I want to know if I'm okay to leave the beer in the primary for a month or so, as many are now doing. Sorry for the noob question.

Yes, you can primary in it, and you can leave it in for aging. Since its already filled with CO2, and air can't get in, the headspace issue isnt an issue. If you were transferring into it as a secondary vessel, it would be an issue since CO2 production would be minimal.
As Aubrey said, it's fine. CO2 is heavier than oxygen; it won't "float" out and allow oxygen in. Also, you can read a ton about autolysis if you want, but it doesn't seem to be an issue (this, from someone who secondaries!). Just leave it in the primary for a month and the CO2 blanket will protect the beer while the particulate matter falls out of suspension.
