    Anyone else do it?

    Purge the keg through the liquid out post for a couple minutes, venting the top.

    Racking cane in a carboy cap, sterile filter on the line from the co2 regulator. Pop the regulator to around 1-2psi, and allow the beer to flow from the racking cane to the beer out post to gently fill the keg from the bottom up?

    Beer never touches the air, and never gets splashed in an environment ripe with oxygen.

    I put my dryhops in the bag if I'm giving it another round of hops, hang it from the PRV, and then I purge the keg so I don't have to open it again until I remove the hops, and then purge the headspace again.

    Other than getting some pressure on the carboys, it's a pretty sound way to move beer around, I get the carboys above the keg to help the siphon to work better and not having to use as much co2 pressure as well.

    Been thinking about racking from one keg to another as well after the last dryhop to avoid even opening the keg, but wonder if it's overkill, myself.

    If you tie up the hop bag using just enough line to have the hops submerged, you could remove the hops from the beer by transferring a few pints to your stomach

    Fair enough, but I usually use whole leaf, so I give the bag a little more room to move. I sometimes put the keg upside down and allow the hops to attempt to float, which holds them in the beer better than floating them. I do it for 2-3 days and then right side up it goes.

    Yep, I do it all the time. My normal primary is a bucket, so I'm using an auto-siphon to the liquid-out post. When using a carboy I use the racking cane through the orange cap to the liquid-out with CO2 giving it a push.


    Not overkill at all. I do exactly this when a spare keg is available . . . the hops stay behind until all the beer has transferred. A quarter-turn on the PRV (receiving keg) and you're good to go. CO2 is your friend.

    I always do closed transfers for my hoppy beers and often do them for my non-hoppy beers as well.

    So you have to take the lid off your bucket to start your siphon? I use buckets as well and am interested how you rack to keg in a closed manner with a bucket?

    From the bucket-to-keg the beer is exposed to air. But I attach a swivel nut to end of siphon tubing and connect to the liquid-out post. This eliminates splashing and the exterior of the tubing never touches the beer. Carboy-to-keg and keg-to-keg are closed.

    As koopa mentioned, this isn't restricted to hoppy beers. I have two 3 gallon'ers on my keezer hump that are regularly filled by a closed loop from the larger cornies.

    For @FATC1TY: My empties are always stored with sanitized water which is purged before a transfer. Usually some starsan foam is left behind. When transferring in through the liquid post it is common to see the foam "percolate" out through the PRV . . . I consider this normal and it probably even helps sanitize.

    I just recently started doing all my kegs this way. I used to CO2 force rack to the bottom of a purged keg by removing the lid and dropping the tubing in, but this last time I did it through the liquid out on all 3 kegs of IPA. I also jumpered them to a new keg after carbing them and allowing them to clear, now I don't have to worry about yeast and hop debris getting swirled into solution when I move the keg. Some of the best drinking IPAs I have made to date.

    WARNING: If you do this, do not purge the keg and leave it closed! My first time doing this I had the keg purged at 40 psi and didn't have the PRV opened. When I hooked up the QD to the post it shot 40psi into my closed system under my carboy cap and made the whole Better Bottle boom and jump. Had the carboy cap not popped off it would have exploded the vessel.

    What the brewer meant to say was "swivel nut with barb":
    [​IMG] My siphon tubing is 1/4" so I use a 5/16" barb. I have flare fitting on my liquid post that this attaches to. If your post has a barb fitting just slip the tube over it . . . may need a hose clamp or cable tie, but you're dealing with really low pressures so this isn't super critical.

    tsk, tsk

    recently bought one of the speidel 60L fermenters with a spigot on the bottom. Put a liquid out disconnect on the end of the hose and rack into a purged keg that way (purge the hose as well). I still get oxygen entering the fermenter, so looking for ways to close that end off, but for now it's open...maybe get another spigot up top. Way better than auto-siphon out of a bucket though...

    So if you are using the orange carboy cap to push co2 in and beer out do you just buy a racking cane to stick in the top? Do you have to buy a fitting to hook up the CO2? And is a sterile filter for the CO2 really necessary?

    I personally have a SS racking cane in mine. I also bought a flare tip to barb fitting that allows me to attach the swivel nut at the end of my CO2 line to the carboy cap. Like this.

    I do like whats in the link, except, I have a liquid out ball lock on the end that ends up gently filling the keg from the bottom up while it's sealed up and the PRV open to vent the keg to allow it to fill.

    I might have to use some extra liquid posts and some lines and make a jumper and start racking from keg to keg for some transfers of IPA's after dryhopping.

    You could always put a bottling valve on the bucket just above the level your yeast and trub typically settles at. Set the bucket on a higher surface than the keg and allow everything to settle out. Open up the valve with the other end of the tubing attached to the keg, and gently force the CO2 into the bucket. Maybe get one of the pieces I talked about in my post above and insert it in a rubber bung to keep the system closed? Not sure if this would all work, just speculating.

    Drill a hole in your lid that will hold a bung with your racking cane. Put a flare fitting on a grommet and have it into the other existing hole. Or have another hole in the lid for another airlock, and have a co2 tubing set up that would fit into, via a nipple or something you slip into the grommet. Your choice really, just need a way to keep lid on and feed co2 into there at very low pressure.

    You can feed the co2 through the top, and have the bucket higher than your keg. You'd need just enough pressure to get the beer moving at first, and you'd be good to go.

    what's cool is I just wrote an article i submitted two weeks ago for the december byo the with this as a big piece of the puzzle...talking about considerations for a great hoppy beer. #thankyoupeterwolfe. Here is a great link that I remember utilizing back in the day when I first set up my carboy cap:

    So I am a fairly new homebrewer and have been using a friend's bucket for fermentation. I have a fridge with temp control to ferment. I am looking to buy my own stuff and I really like the speidel. Mostly because of the easy cleaning and the spigot. I rarely transfer to a secondary and usually just dry hop in the primary. I hate taking gravity reading via auto Siphon and also dislike transferring to a bottling bucket.

    Can you use the spigot to draw gravity samples and bottle or rack to a secondary with the spigot as opposed to using a shipon?
     
  24. telejunkie

    telejunkie Savant (1,095) Sep 14, 2007 Vermont

    I've been very happy with the speidel so far. Definitely a step up from the buckets, easy to clean the spigot, handles are strong and I like the design of the fermenter.

    For dry hopping, that is what i've been doing. You just have to be really careful when drawing gravity samples, you don't want to draw it then leave it with wort still clinging to it for several days. You may come back with a mushroom plug. As long as your diligent about rinsing it, then you should be fine. Also the airlock opening is more than big enough to stick a thief in to draw a sample.

    You're very lucky you were using a Better Bottle rather than a glass carboy. Why 40psi? I purge my kegs at 10psi... when the O2 is gone, it's gone.

    Cool setup overall; I will play with this to simplify things a little. I will mention that the sterile filter on the CO2 is probably overkill; if all the fittings are sanitary, it's very unlikely that any contamination will come from the gas...just saying because those sterile filters cost money. But if you have a cheap source, why not use them?

    I had them laying around to be honest. I had a few because I use them on the inline of my oxygen tank set up as well.

    I normally just slam the co2 into my kegs as well. I don't know why, maybe just habit. Not sure if that was the case with him.

    That said- I'm pretty aware of what I have downstream as far as pressure before I open anything. More of a habit due to my line of work as well.

    40psi into a glass carboy would have me.. clinching my butt cheeks.

    Trying to seat a lid that just wouldn't stop leaking, and flushing as much O2 from the hops as I could. Ended up using quite a bit of keg lube and hitting the rim with a hammer to get it to form correctly to the lid. Worked. Def not gonna do any of that 40psi stuff again.

    You gotta figure that jbakajust1 does everything to the extreme: "Ended up using quite a bit of keg lube and hitting the rim with a hammer to get it to form correctly to the lid" . . . see what I mean!

    Actually the orange cap will pop off at a fairly low pressure. Lots of reviews have customers complaining about how difficult it is to keep the cap on a carboy as they add pressure. Not sure this is by design but you want the cap to fail before you-know-what happens. My grip can not keep it on much past 4 psi, so it's unlikely any brewer will be getting the Darwin Award from a failed carboy. Now anyone foolish enough to clamp it down . . . :grimacing:

    I'll post a picture of my racking set up tomorrow. It's the same for moving to another carboy or to my barrel. I add the liquid in line for the kegs.

    Need to buy another ball lock post for the jumper, and maybe another keg. Hah!

    Is using the sterile air filter really necessary? I mean, after all, there seems to be no need to connect one between a co2 bottle and a keg. I'm only asking because I'm wondering if I might be overlooking something here.
     
  38. FATC1TY

    FATC1TY Initiate (0) Feb 12, 2012 Georgia


    No.. no real reason. There's a sinistered filter on the regulators in most cases.

    I have extras around as well, I also have a line that comes off a 4 way splitter that stays connected in my keezer, that I drag around for various things, like purging and racking, so it can get crap in it, so I've just done it like that before.

    If you blow into your cap to start a siphon like mentioned above, I'd use the filter as well.

    To update this:

    I've been drinking my IPA and.. Xtra Pale.. Both were fermented the same temp, flushed with co2 in the primary. Dryhops added while the fermentation was dying down, flushed after the hops were added.

    Racked via co2 to the kegs through the out post. Flushed the keg well, pushed all the starsan out, then flushed the lines and racking cane with co2. Pretty much EVERYTHING was flushed, and easily at that.

    Racked to the kegs, purged, and then set to carbonate.

    I can tell a marked difference in the beers from ones in the past where I was a little lax in racking them around from primary to keg, and even hopping in the keg.

    My aroma during the pour from the tap is very, very aromatic. The flavor is just so much more crisp, and spot on. By this time, I would have picked up on some oxidization of my hoppy beers, and would have a more muted aroma and flavor.

    Between packing in the oils with the hopback, and racking via co2 throughout the process, I believe this is where people end up unhappy with their hoppy beers after some time.
