Corny Keg as Primary
 
I've read a few posts about this, and I'm convinced that I'm going to use corny kegs for primaries and secondaries, but still have one question that's bugging me:

Does anyone use a corny as a primary, and how much wort do you put in there? I'm willing to modify my recipes for 4.0-4.5G batches if I need to, but would rather not. What I'd actually do is probably boil 9G batches, and use 2 cornies as primaries etc. I'm planning to use a blowoff tube attached to the Co2 QD.

If I can't find any recommendations, then I'll go forward and do a normal 5G batch and see how it works out, then post the results.

Thanks

You're not going to have much headspace if you are doing 5gal batches. Plus you'll have a very dirty corny to clean. Not a problem if you have skinny arms but mine are fat enough I can't reach the bottom of the corny.

I'd stick with using them only for secondaries.

I have not done this, but a bottle of Fermcap-S from NB will definitely be your friend in this experiment.

I'd remove the QD post and tube then attach the blow off tube to the QD treads

See this months HTB...article all about it. It didn't make me want to try it, but I would imagine there's a pointer or two in it for those that do.

That's what I do - brew a 8-9 gallon or a 12-13 gallon batch - and split it into two or three cornies. Works like a charm. I use a blowoff hose (1/2" id)forced over the threads on the gas in post. Sometimes I use foam control. The split batches gives me a chance to dry different yeasts, etc.

I shortened one diptube - cut off 2" and then straightened it as much as I could. Another brewer I have discussed this with uses a diptube from a pinlock keg - they are straight. I have been leaving the diptubes in the kegs, but next time I will leave them out and just insert the sanitized straight tube at racking time.

Cleaning is not a problem if you do it soon after racking. All the sticky stuff is at the top where I can reach it easily.

do you not have any primaries? i would just use carboys and transfer to keg for secondary.

Ever broken a carboy? It's not pretty.

I use buckets or cornies - carboys are overrated.

Especially when it is one you are cleaning, getting yeast out of the cuts is not fun. Yea, I had one shatter and cut up my shins and hands nicely.

Try Better Bottles benefit of a carboy without the added weight and chance of shattering.

i've broken two carboys. both times it was because i did something stupid.

the weight sucks and the chance of breaking is higher. other than that, they are the best IMO. so much easier to clean, will last forever, and i still like to see what's going on with my fermentation.

start fermenting in kegs and i think you'll need to take them apart every few times you use them just to ensure they are clean. just seems like more trouble than its worth to me. if you're worried about shatters, i would agree with budbo on trying the better bottles.

keg for the secondary is great, tho. from there you can cold condition and tap straight from the keg, you could use it as a bright tank, or you can filter to another keg. it gives great options.
