Hotpacking wort into a corny keg?

    Anyone ever hotpack wort into a corny keg? I'm talking about pouring say, 180 degree wort straight from the kettle into the keg, slapping the lid on, and letting it cool on it's own. Concerned about damage to the rubber feet and handles of the keg, could they possibly fall off? Anything else I'm not considering? Thanks.

    first and foremost, sanitize the shit out of that thing, incase your 180F wort doesn't kill absolutely everything living in the clean keg. i might be concerned with hot side aeration, unless you are running it through the liquid out post directly into the bottom on the keg, but that being said, there is evidence that this concept is almost a myth and you'd really have to F up and splash the crap out of it to have a negative effect.

    i say go for it and report back.

    I haven't done this, but I know some people have cleaned/sanitized their kegs by pumping boiling/near boiling water through them, apparently without issues.

    I pour 160 deg water out of my water heater straight into my kegs to soak with oxiclean and it's fine but 180 and hotter Im not sure about. No help I know. One thing is you should be fine with sanitizing since you are that hot. Are you transferring the wort to another location to ferment?

    Thanks for your input kneary13. I'm not concerned about damage to the wort, this is not meant to be a discussion about hot side aeration, my concern is whether the keg will be able to withstand the heat without some sort of damaging occurring to it. Obviously damaging the steel isn't an issue, I'm just concerned about the rubber parts falling off or the keg getting damaged in some way that I'm not considering.

    If it were me, I'd post on here. If I didn't get a few, 'I've done that with success' stories, I'd do a test batch with at least 4 gal of water.

    I wonder what John Palmer would do....

    I've routinely sanitized cornies with 190F water, with no problems. I don't do this at home, but have grown yeast for a brewpub a few times, and we always sanitized with hot water at the brewery. I suspect that the rubber parts might come off if you immersed the entire keg in hot water but just filling it doesn't seem to be a problem.

    edit: I have had the feet come off a couple of kegs for no apparent reason; at least one of them had never been heat sanitized. I reattached them with Gorilla Glue and they have been fine for the last 5-6 years.

    What'd the water taste like when it came out? That's a better question than will the seals hold up?

    skivtjerry Zealot (524) Mar 10, 2006 Vermont

    I never tasted it, as it was a little warm. It had no odor and the wort used to step up the yeast always tasted just fine the next week. The keg was cleaned very well before heating and use.

    I have used near boiling water and oxy clean several times without the rubber bits falling off. No problems to report either. HB42 good luck!

    I rinse the Iodine solution out of my kegs with 2 gallons of boiling water. I have had no issues with my kegs .

    I'm not in the Corney keg business, nor do I package commercial beverages. However, I can only assume that the larger packaging companies, like Coke or Pepsi, are using some type of dishwashing machine to clean and sanitize their kegs before filling. The commercial dishwashers in restaurants run 180f. So, my guess is that you would be O.K.
    Maybe someone in the know can elaborate on this.

    Just out of curiosity , what are you going to do with the beer once its in the corny ?
  19. Homebrew42

    Homebrew42 Initiate (0) Dec 20, 2006 New York

    Ferment it.

    I've never heard of this. Would you transfer again or just tap keg as is?

    Seems to me that it would have to be transferred as the amount of yeast/trub on the bottom would be way too thick. Unless the dip tube were cut to a length that would rest above the yeast cake which would likely be a guess at best.

    I figured as much and did some homework and that appears to be the case.
  23. Homebrew42

    Homebrew42 Initiate (0) Dec 20, 2006 New York

    I would transfer again to get the beer off the yeast cake. It's not unheard of to use a corny as a fermenter.

    Yeah, a nice advantage of using this method is that you can ferment then use CO2 to push from a keg to another keg and introduce no oxygen in the process.

    I did something similar to this with my last beer. I drained my kettle directly into my corny and then pumped it through my jockey box to cool it on its way to the carboy. It worked pretty well but I need to adjust how I cool the wort. As far as I can tell there was no damage to the keg. I took it apart to clean the hop break material and the o-rings seemed fine to me.

    Haven't tried it yet, but cleaning the keg afterwards seems like a big negative, although as OddNotion pointed out, the oxygen exclusion should be a real plus.

    I wonder if adding a gallon or two of boiling water to the keg, and then sealing it would adequately sanitize/sterilize. The steam that would be trapped in the keg would probably get everything but the inside of the dip tube and liquid out post?
  28. inchrisin

    inchrisin Defender (654) Sep 25, 2008 Indiana

    I'm assuming that first 30 seconds of pour is going into a mason jar for yeast washing and then you jump the rest of the beer to a second keg and you're ready to go?

    Hey nice to see you back. Who was the supplier that sold altered Cornies to be used as a fermenter? Didnt johnnylieberman use them at some point? I want to say whoever it was though they didnt have rubber parts like a handle or feet-only the seals I am thinking. I can see the pictures but not sure where I saw them.

    i've done it a few times (transporting from a brew competition to the house). i've yet to damage the cornies.

    Im thinking this might be the perfect vessel to conduct a sour mash. Easy to purge with CO2, keep air tight and a good conductor of heat. It also fits perfectly in my ferm chamber which I can get up to 110 degrees.

    I use boiling water to sanitize my kegs all the time. I add about 3 gallons of boiling water and shake the crap out of it. I then use a screw driver and push down on the posts to blow steam out of them (I burned myself the first time doing this so watch out) the point being they hold up fine to boiling temperatures.

    Yes, cornies are basically the ideal sour mashing vessel.

    Whether or not sour mashing is the ideal souring method...

    I wouldn't worry about the heat affecting the corny. It may on certain kegs soften the glue and result in the bottom rubber part falling off, but this is unlikely and the risk just seems too low to really worry about.
