How much headspace in keg

Once full I set to 20psi put it on the floor and rock back and forth for a minute. Leave it stand in the fridge for an hour or so and serve. DavidHatton Junior Member. Would like some advice and didn't want to start another thread, I am serving with a soda stream bottle and kegland regulator, no fridge, after serving, what is the best idea for the headspace left by pulling off your beer, I put some co2 in before I disconnected the gas.

This is my process: I fill my corny with about 17 litres and then I use the quick burst carb method - 40psi with very cold beer, keg on its side and rocked for a count of I then set the pressure to 15 psi and turn off the gas. I leave for about 30 mins and the beer is usually now about 20psi. I then draw off a pint of so with the gas off still. Then when I next drink I turn the gas back on still set at 15psi and it sometimes will add a little back in, and leave the gas on the while I am drinking - you'll be able to see the pressure in the keg on the regulator.

That might be 5 mins or 5 hours. Then I turn it off again as I might not pour again for a week, and I feel there is a chance I'll have a leak somewhere and don't want to waste gas. This keeps my beer carbed to the level I like, keeps the headspace full of co2, and reduces the risk of me returning to an empty gas canister due to a leak.

I'd reset and resealed since then, and don't think I have a leak - but since it is so little effort to turn the gas off, I do. I also drink fairly intermittently, sometimes a lot and sometimes barely any, so chances of a leak running down without me noticing is high. Gas is cheap but it is a long drive for me! I also have a 4 way manifold to allow me to turn lines on an off as I carb my fizzy water at 60psi for speed.

But since I only have the one regulator, it seems easier to turn on and off. I'm sure there is a reason this is 'wrong' but I don't want to spend any more cash currently. I also keep my gas in the keezer - again this is 'wrong' I believe but I'm putting off making a collar and I don't need the extra room yet Does bottom filling a non-purged keg force oxygen out, leaving it only in the headspace, which can then be purged?

Add it to the list! If you have any thoughts about this xBmt, please do not hesitate to share in the comments section below! All designs are available in various colors and sizes on Amazon!

An interesting experiment, I never thought about losing hop aroma from purging the headspace.

So much of the aroma will be safely in solution in the beer, rather than purely in the headspace. I would be very interested to compare a CO2 purged keg VS unpurged keg at filling, where both then have the headspace purged after filling. I think the oxidation focused experiments would really be served by the addition of dissolved oxidation measurements. For a few hundred bucks I would think you could get a decent meter and really enhance the evaluation of any effects.

Was it the hop combo or the more restrained hop usage or what specifically? Hop combo was just right, and using less meant no astringency or excessive bitterness something I find too much of in most commercial NEIPAs. I will continue to try them out! This makes me think that volume might have some role in this. Or, perhaps, volume plus pasteurization.

Did you notice any other differences long term in color, taste, etc? When filling my kegs with any beer, I flush the keg with co2 and then purge the head space with co2 about 8 times. There is unlikely to be many aroma compounds out of solution at that point, and when they are scrubbed from the beer, they stay out of solution anyway. Also, aroma scrubbing tends to happen when using a carbstone without adequate head pressure on the vessel to keep compounds in solution.

If so, and the kegs were purged of oxygen prior to packaging, what is the point of purging the headspace if it is only C02? I used to just burp my kegs a few times and then fill under pressure, and was getting oxidation — especially in NEIPAs where the color would go dark and become much sweeter. Now I fill kegs completely with starsan, flush it with co2, and then do a closed transfer to the keg. Glass and plastic carboys are extremely popular fermenting vessels, and filling a keg from one is much like bottling.

You will need to siphon the beer into your keg through the lid. This requires you to depressurise the keg and carefully, partially remove the lid.

You can cover any gaps with sanitised tin foil or kitchen roll to prevent excess oxygen entering. Once ready to siphon, insert your sanitised hose, preferably to the bottom of the keg to avoid splashing and introducing excess oxygen. Start the siphon, and carefully monitor how much beer is entering the keg. If your fermenting vessel is fitted with a tap, you can fill your keg without removing its lid, reducing the chance of oxidation. You will still need to release the pressure from within the keg before you start filling; if the pressure in your keg is greater than in the fermenter, it will not fill, and is more likely to release a burst of co2 into your fermenter, disturbing the sediment.

Once depressurised, fit a sanitised hose to the tap on the fermenter, and fit the other end onto the beer disconnect on your keg. This will allow the beer to enter the keg via the dip tube, preventing it from splashing. Open up the tap on the fermenter and let the beer flow into the keg.

The easiest way to do this is to fit an open tap or valve onto the gas disconnect, otherwise you can simply pull the release valve when necessary or partially open the lid.

This method will entirely remove the risk of oxidation as long as your keg has been purged. So it seems that I should definitely not repeat this stunt, and risk infecting my next batch in this keg until a complete dis-assembly and cleaning. Be careful with the really full keg. If the gas in dip tube is down in the beer, there is a really good chance that you will end up with beer in your gas lines when connect it to the gas. That is most certainly gonna happen here. I gues I will have to get one of those check valves for my setup with the new hose.

I always purge hot oxyclean and then starsan through both dip tubes when I clean a keg but this news still makes me nervous. Check valves are a great idea.
