This has been said basically but I'll share my way. I fill one keg with starsan, connect beer-to-beer to another keg. This keg in turn is connected gas-to-beer to a third. So what this does is empty my next to be used keg of starsan and purged of oxygen. Fill the next in line with starsan to capacity. Any overflow goes to the third.

Great idea!

Personally I would start with a full keg of Starsan 🍻

Great tip! I do the same, except I transfer the star-san from Liquid out post to liquid out post to keep the foam down, and just turn the keg over for contact on the top of the keg. really limits the amount of star-san that remains in the keg after the transfer out. Works either way tho!

Oh wow! Thanks for the tip. We will give that a try. Cheers!❤️

I'm curious, how much CO2 does this process use up?

Honestly not much at all. I will make a note to film the gauge the next time we do this and let you know. My orher thought is I can ask at the welding supply shop to see if they know or if there a mathematical equation we can use to figure it out. Cheers

Thank you. The reason I asked is that refilling in my area is both inconvenient and not exactly cheap.

@@dden7670 I understand completely. I'm not sure if this is an option for you, but we found that a liquor store that sells kegs of beer, sells CO2 much cheaper than a welding supply store or homebrew store.

@@ayetobee8461 the reason we do it this way is because we know the kegs are cleaned, sanitized and ready to go. Might be a good option if CO2 is not readily available.

Did you just fill an empty keg with CO2 to clean/purge it, why? That will waste many, many ounces of CO2. Fill it with starsan and water first. Then use CO2 to pump it out at a few PSI while you do something else. This uses hardly any. You can also hydro-staticly pressure test while it's 100% full with virtually no gas, all the way up to 60PSI. Better yet. If you use a pressure fermentor with a ball-lock gas line, you can use fermentation CO2 to flush, sanitize, purge and pressurize (to up to 20PSI) with a single ferment. A 22L batch of lager produces over half a kilo of CO2! Yeast will be absolutely dandy in 1 bar/15 PSI and ferment cleaner. So... pressure ferment at 15PSI and use that 15PSI 'waste' pressure to maintain your kegs. If you cold crash the fermentor to 2C and can retain even 12PSI of the ferment pressure, the beer pressure transfers to the keg, fully carbonated already. You could process half a dozen or more kegs, ferment faster and still have enough "free" gas left to carbonate the beer it's coming from.

Hello, we fill with Starsan after the keg is clean and then push out. You are correct this uses very little c02. Thanks a pint for the additional information I bet many who have trouble getting c02 will benefit from all the information that you provided. Thanks again for responding. Cheers
